Currently, bandwidth resources are often shared by multiple services. In order to improve the utilization of resources, a flow control method is usually used to control the bandwidth occupation of the service. Different services have different bandwidth requirements. For services that require high bandwidth stability, you need to configure guaranteed bandwidth to provide reliable service bandwidth. Even in the case of a bandwidth conflict, the service can be guaranteed to be forwarded preferentially. The configured service bandwidth is converted into the traffic control parameter of the service port inside the device. When the traffic control is performed on the data packet, the device uses the flow control parameter to perform flow control.

For tunnels and pseudowires carrying fixed service bandwidth, guaranteed bandwidth must be provided to guarantee the quality of service for such services. Correspondingly, on the physical or logical port carrying the service, an appropriate bandwidth reservation must be provided as a fixed bandwidth reserved for such services. At present, the bandwidth guarantee configuration method can solve the bandwidth guarantee problem of the service, but lacks flexibility, and cannot satisfy the user requirement that the service has guaranteed bandwidth in the first specific time period, and in the second specific time period (the second specific time period is only The bandwidth requirement is lower relative to the first specific time period, thereby reducing the bandwidth utilization.

Embodiments of the invention

Embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

A bandwidth reservation method according to an embodiment of the present invention may be used to implement bandwidth reservation for a bandwidth control device (ie, a bandwidth reservation parameter configuration device) in an Ethernet, where the bandwidth control device may include a user for receiving a port bandwidth reservation configuration unit configured to input a preset time period and a port bandwidth reservation configuration parameter corresponding to the preset time period, and a port for verifying parameters configured by the port bandwidth reservation configuration unit a bandwidth reservation check unit, a port bandwidth reservation configuration holding unit for saving parameters configured by the successful port bandwidth reservation configuration unit, a bandwidth for initiating the service creation process, and a bandwidth sent by the port bandwidth reservation configuration unit. a service configuration unit that reserves the configuration check and forwards to the service bandwidth reservation check unit, a service configuration save unit that stores configuration data of the service, and a service bandwidth reservation for verifying the resource reservation configuration of the port Calibration unit.

In the process of implementing the service bandwidth reservation, the port bandwidth reservation configuration unit receives the preset time period input by the user and the configuration information of the port bandwidth reservation configuration parameter corresponding to the preset time period, and sends the configuration information to the port bandwidth pre-configuration. The check unit is checked for verification. After the port bandwidth reservation check unit is successfully verified, the configuration information is sent to the service configuration unit; otherwise, if the port bandwidth reservation check unit fails to verify, the information of the port configuration information verification failure is returned. The service configuration unit forwards the received configuration information to the service bandwidth reservation check unit for verification. If the service bandwidth reservation check unit successfully checks, the configuration information is sent to the service configuration unit, and is forwarded by the service configuration unit. The configuration unit is reserved for the port bandwidth, and then the port bandwidth reservation configuration unit sends the bandwidth reservation configuration storage unit to the port for storage; if the service bandwidth reservation check unit fails to verify, the service configuration information verification failure information is returned. .

When a user requires a certain service to have guaranteed bandwidth within a certain period of time and does not guarantee bandwidth requirements in another time period, not only the bandwidth parameter is required to be provided during service configuration, but also Configure bandwidth reservation on the port corresponding to the service. Therefore, the bandwidth reservation can be used to ensure that the port of the access service can carry the service of the guaranteed bandwidth within a limited range, and the resource conflict is effectively avoided during the creation of the service phase, thereby providing reliable bandwidth guarantee for the service.

As shown in FIG. 1, an embodiment of a bandwidth reservation parameter configuration method according to the present invention is shown. The bandwidth reservation parameter configuration method in this embodiment includes:

Step 10: Receive a bandwidth reservation parameter of a port configured by the user; the bandwidth reservation parameter includes a bandwidth reservation and a preset time period;

In this embodiment, the bandwidth reservation parameter of the port configured by the configuration unit is configured by the port bandwidth reservation, where the bandwidth reservation parameter includes a preset time period and a bandwidth reservation corresponding to the preset time period, and the port may be Physical port or logical port. The preset time period may be divided into multiple time periods, or may be flexibly set according to actual conditions. The bandwidth reservation may include: static guaranteed reserved bandwidth, dynamically guaranteed reserved bandwidth, peak reserved bandwidth, and port convergence ratio. The guaranteed reserved bandwidth may include a static guaranteed reserved bandwidth and a dynamically guaranteed reserved bandwidth. The static guaranteed reserved bandwidth includes a specified service flowing from one port to another when the service is created, and the dynamically guaranteed reserved bandwidth includes service creation. When the service is generated according to the protocol, it flows from one port to another port, and the peak reserved bandwidth includes the maximum bandwidth that the service flows through.

The following is an example. Take an Ethernet physical port as an example. Assume that the available bandwidth of the physical port (that is, the port rate) is 100 megabytes (M). You can set the first preset time range from 00:00 to 11:59. And the bandwidth reservation parameters configured during the time period include: static guaranteed reserved bandwidth can be set to 100M, dynamic guaranteed reserved bandwidth can be set to 80M, peak reserved bandwidth can be set to 200M, and port convergence ratio can be set to 80%; set the second preset time period from 12:00 to 23:59, and the bandwidth reservation parameters configured in the time period include: static guaranteed reserved bandwidth can be set to 200M, dynamic guaranteed reserved bandwidth can be set For 100M, the peak reserved bandwidth can be set to 300M, and the port convergence ratio can be set to 80%. At this time, in the two different time periods, two different bandwidth reservation configurations are provided, wherein the bandwidth reservation in the second preset time period requires bandwidth reservation than the first preset time period. many.

Step 20: Determine whether a bandwidth reservation meets a preset condition in each preset time period;

After the bandwidth reservation parameters of the port configured by the user through the port bandwidth reservation configuration unit, in order to ensure that the bandwidth reservation allocation does not conflict during each preset time period, the preset needs to be performed. The time period and the bandwidth reservation corresponding to the preset time period perform the first check; and in order to ensure that the service is in use, the current service does not conflict with the allocation of the bandwidth reservation in each preset time period. A second check is performed on the preset time period and the bandwidth reservation corresponding to the preset time period to determine whether the preset condition is met. The preset condition may include a first check condition and a second check condition.

First, the first check is performed on the port bandwidth reservation check unit. If the first check is unsuccessful, the bandwidth reservation check configuration failure information of the port is prompted, that is, the bandwidth reservation is not performed in each preset time period. The first check condition is met; if the first check is successful, the second check is performed by the service bandwidth reservation check unit. When the second check is unsuccessful, the bandwidth reservation check configuration of the service fails, that is, the bandwidth reservation does not satisfy the second check condition in each preset time period; when the second check succeeds, it is determined that The bandwidth reservation meets the preset condition in each preset time period.

Step 30: Associate each preset time period with a corresponding bandwidth reservation when the bandwidth reservation meets the preset condition;

After the second verification succeeds, the reserved bandwidth configuration of the port does not conflict with the current service, that is, the bandwidth reservation meets the preset condition, and the preset bandwidth is saved by the port bandwidth reservation configuration unit. The storage is associated with the corresponding bandwidth reservation. If the bandwidth reservation does not meet the preset condition, if the second verification fails, the bandwidth reservation configuration is not saved.

Optionally, if the bandwidth reservation parameter does not include a preset time period, the bandwidth reservation is reserved as a real-time bandwidth. It should be noted that if the bandwidth reservation parameter of the port configured by the port bandwidth reservation configuration unit is not configured with the preset time period, the bandwidth reservation defaults to all the time, that is, the bandwidth reservation is reserved as the real-time bandwidth. .

In the embodiment of the present invention, the user configures the preset time period of the port and the bandwidth corresponding to the preset time period, and the bandwidth reservation satisfies the first check condition and the second check condition in each preset time period. When a preset condition is met, each preset time period is associated with a corresponding bandwidth reservation for storage. The user can perform bandwidth reservation configuration for different time periods, meets the requirement that the service required by the user has a guaranteed bandwidth within a preset time period, and improves the utilization of the broadband.

Optionally, as shown in FIG. 2, based on the foregoing embodiment, in the embodiment, the foregoing step 20 may include include:

Step 21: Determine whether the sum of all static guaranteed reserved bandwidths of the port and all dynamic guaranteed reserved bandwidths is less than or equal to the available bandwidth of the port, and whether the peak reserved bandwidth of the port is greater than each of the preset time periods. Or equal to the sum of all static guaranteed reserved bandwidths of the port and all dynamic guaranteed reserved bandwidths;

After the bandwidth reservation is configured in each preset time period, in order to ensure that the allocation of the bandwidth reservation does not occur in each time period, the bandwidth reservation check unit needs to reserve the wide port. The parameter is checked for the first time, that is, all the preset time segments and the bandwidth reservation corresponding to the preset time segment are uniformly verified, and the allocation of the bandwidth reservation is not required to be generated in each time segment. The first check condition for port check bandwidth reservation may be: for each preset time period, for all ports: all static guaranteed reserved bandwidth plus all dynamic guaranteed reserved bandwidth is less than or equal to the available port. Bandwidth; at the same time, the peak reserved bandwidth of the port is greater than or equal to all static guaranteed reserved bandwidth of the port plus all dynamic guaranteed reserved bandwidth. If the first check condition is met, the first check succeeds, and the port bandwidth reservation check unit sends the bandwidth reservation parameter of the port to the service configuration unit. On the other hand, if the first check condition is not met, the first check fails, and the bandwidth reservation check configuration failure information of the return port is returned. The user can re-configure the bandwidth reservation parameters according to the information.

Therefore, according to the above set parameters, the static guaranteed reserved bandwidth 100M plus the dynamic guaranteed reserved bandwidth 80M is equal to 180M and less than the available bandwidth of the port 1000M in the time range 00:00 to 11:59. At the same time, the peak reserved bandwidth of the port 200M is greater than the sum of the static guaranteed reserved bandwidth and the dynamic guaranteed reserved bandwidth of 180M. Therefore, the parameters configured during this time period satisfy the first verification condition. During the period from 12:00 to 23:59, the static guaranteed reserved bandwidth of the port is 200M plus the dynamic guaranteed reserved bandwidth of 100M is equal to 300M, which is less than the available bandwidth of the port by 1000M. At the same time, the peak reserved bandwidth of the port 300M is equal to the sum of the static guaranteed reserved bandwidth and the dynamic guaranteed reserved bandwidth of 300M. Therefore, the parameter configured in the time period also satisfies the first check condition, and the bandwidth reservation parameter satisfies the first check condition.

Step 22: If the sum of all the static guaranteed reserved bandwidths of the port and all the dynamic guaranteed reserved bandwidths is less than or equal to the available bandwidth of the port, and the peak reserved bandwidth of the port is greater than or equal to all the static guarantee pres of the port. The sum of the reserved bandwidth and all the dynamic guaranteed reserved bandwidth is judged at each Whether the product of the guaranteed bandwidth sum of all services passing through the port and the port convergence ratio is less than or equal to the sum of all static guaranteed reserved bandwidths of the port and all dynamic guaranteed reserved bandwidths in a preset time period;

After the first verification of the bandwidth reservation in each time period is successful, in order to ensure that the service is in use, the current service does not conflict with the allocation of the bandwidth reservation in each time period. During the service creation process, the service configuration unit needs to allocate bandwidth for the service, and performs a second check on the bandwidth reservation parameter of the port forwarded by the service configuration unit by using the service bandwidth reservation check unit.

In addition, after the first verification of the bandwidth reservation parameter in each time period is successful, that is, the sum of all static guaranteed reserved bandwidths of the ports and all dynamic guaranteed reserved bandwidths is less than or equal to the available bandwidth of the port. The peak reserved bandwidth of the port is greater than or equal to the sum of all the static guaranteed reserved bandwidths of the port and all the dynamic guaranteed reserved bandwidths. When the service is created, the peak reserved bandwidth of the port is configured as the peak value of the service. Leave bandwidth. At this time, it is not necessary to further verify the peak reserved bandwidth, thereby facilitating the use of the peak reserved bandwidth of the service.

It should be noted that multiple services may exist in one bandwidth, and each service may be configured with different or the same service bandwidth reservation parameters in multiple different time segments. This service refers to tunnels with end-to-end link relationships, pseudowires, and the end-to-end services they carry.

Optionally, the preset time period requirement of the bandwidth and bandwidth of the service needs to be compared with the bandwidth reservation and the preset time period of the port, and the bandwidth reservation configuration of all the services of the port and the preset time period are matched with the port. Bandwidth reservation and configuration of its preset time period. The second verification condition of the bandwidth usage reservation of the verification service may be set as: the sum of the guaranteed bandwidths of all services passing the configured port multiplied by the port convergence ratio is less than or equal to the port in each preset time period. The sum of all static guaranteed reserved bandwidths plus all dynamic guaranteed reserved bandwidths. If the port has been configured with traffic before the bandwidth reservation parameter of the port is configured, you need to directly send the configured parameters to the service bandwidth reservation check unit for verification.

The following is an example. Assume that the port has been configured with three services in the time range of 00:00 to 11:59. The guaranteed bandwidth of the three services is 100M, and the bandwidth reservation parameters configured in the time range are as follows. Consistent. In this time period, the sum of the guaranteed bandwidths of the three services is 3*100M=300M. At this time, the guaranteed bandwidth of the service 300M* port convergence ratio is greater than 80%=240M. The static guaranteed reserved bandwidth of the port is 100M and the dynamic guaranteed reserved bandwidth is 80M. At this time, there is already a period of time that does not meet the condition, and there is no need to check the time period from 12:00 to 23:59. Therefore, the reserved bandwidth configuration of the port is in conflict with the current service. The failure, that is, the second verification failure, needs to return to the user related configuration failure information, that is, the bandwidth reservation configuration failure information of the returned service. If the service is guaranteed to have only one service and the guaranteed bandwidth of the service is 100M, the guaranteed bandwidth of the service 100M* port convergence ratio is 80%=80M is smaller than the port in the time range from 00:00 to 11:59. The static guaranteed reserve bandwidth is 100M and the dynamic guaranteed reserved bandwidth is 80M. During the time period from 12:00 to 23:59, the guaranteed bandwidth of the service 100M* port convergence ratio is 80%=80M, which is smaller than the sum of the static guaranteed reserved bandwidth 200M of the port and the dynamic guaranteed reserved bandwidth 100M. At this time, the reserved bandwidth configuration of the port is not in conflict with the current service. In this case, the configuration succeeds, that is, the second verification succeeds.

Step 23: If the product of the guaranteed bandwidth of all services passing through the port and the port convergence ratio is less than or equal to the sum of all static guaranteed reserved bandwidths of the port and all dynamic guaranteed reserved bandwidths, each preset time period The internal bandwidth reservation meets the preset conditions.

In this embodiment, when the first check and the second check are successful for the bandwidth reservation in each preset time period, the bandwidth reservation meets the preset condition in each preset time period.

Optionally, based on the foregoing embodiment, in the embodiment, the foregoing step 30 may include:

Add a service to the current service of the port, and determine whether the product of the guaranteed bandwidth and the port convergence ratio of all services passing through the port is less than or equal to all static guaranteed reserved bandwidth of the port in each preset time period. The sum of all dynamic guaranteed reserved bandwidths;

If the product of the guaranteed bandwidth of all the services of the port and the port convergence ratio is greater than the sum of all the static guaranteed reserved bandwidths of the ports and all the dynamic guaranteed reserved bandwidths, the bandwidth reservation configuration failure information of the service is prompted.

Optionally, after each preset time period that meets the preset condition is stored in association with the corresponding bandwidth reservation, the service of the port is in the process of using the bandwidth reservation parameter, when the current port is used. When a new service is added to the service, the second verification described above is required. When the sum of the guaranteed bandwidth of all services passing through the port and the port convergence ratio is greater than all static guaranteed reservations of the port When the bandwidth is the sum of all the dynamic guaranteed bandwidths, the reserved bandwidth configuration of the port conflicts with the service at this time. If the second check is unsuccessful, the bandwidth reservation configuration failure information of the service is returned.

Assume that the current service of the port is 2, and the guaranteed bandwidth of the two services is 100 M. The bandwidth reservation parameters configured in the time range are consistent with the above. In this time period, the sum of the guaranteed bandwidths of the two services is 2*100M=200M. At this time, the guaranteed bandwidth of the service 200M* port convergence ratio is 80% equal to 160M, and the static guaranteed reserved bandwidth of the port is 100M and dynamic guarantee. Reserve a bandwidth of 80M. However, if a service with a guaranteed bandwidth of 100M is created on the basis of the current service, the guaranteed bandwidth of the service 300M* port convergence ratio is 80%=240M, which is smaller than the static guaranteed reserved bandwidth of the port 100M and the dynamic guaranteed reserved bandwidth of 80M. Sum. At this time, there is already a time period that does not satisfy the condition, and it is not necessary to check the time period from 12:00 to 23:59. Therefore, the reserved bandwidth configuration of the port is in conflict with the current service. In this case, the configuration fails, that is, the second verification fails, and the bandwidth reservation configuration failure information of the service is returned.

Similarly, it is assumed that the current service of the port is one in the time range of 00:00 to 11:59, and the guaranteed bandwidth of the one service is 100 M, and the bandwidth reservation parameters configured in the time period are consistent with the above. However, during this time period, if a service with a guaranteed bandwidth of 100M is created on the basis of the current service, the guaranteed bandwidth of the service 200M* port convergence ratio is 80%=160M is smaller than the static guaranteed reserved bandwidth of the port 100M and dynamic guarantee Reserve a bandwidth of 80M. In the time period from 12:00 to 23:59, the demand for guaranteed bandwidth after adding new services is also met. Therefore, the reserved bandwidth configuration of the port does not conflict with the current service. In this case, the bandwidth reservation parameter of the above configuration is valid.

It should be noted that the bandwidth reservation parameter configuration method in the embodiment of the present invention may be implemented by a communication network device, such as a router, a switch, a packet switching network device, or the like as an execution entity.

The embodiment of the invention further provides a computer storage medium, wherein the computer storage medium stores computer executable instructions, and the computer executable instructions are used to execute the bandwidth reservation parameter configuration method.

Correspondingly, as shown in FIG. 3, a first embodiment of a bandwidth reservation parameter configuration apparatus according to the present invention is proposed. The bandwidth reservation parameter configuration apparatus of this embodiment includes:

The receiving module 100 is configured to receive a bandwidth reservation parameter of a port configured by the user; Parameters include bandwidth reservation and preset time period;

In this embodiment, the user may use the bandwidth reservation parameter of the port configured by the port bandwidth reservation configuration unit, so that the receiving module 100 receives the bandwidth reservation parameter, where the bandwidth reservation parameter includes a preset time period and the preset. The bandwidth reservation corresponding to the time period. The port can be a physical port or a logical port. The preset time period may be divided into multiple time periods, or may be flexibly set according to actual conditions. The bandwidth reservation may include: static guaranteed reserved bandwidth, dynamically guaranteed reserved bandwidth, peak reserved bandwidth, and port convergence ratio. The guaranteed reserved bandwidth may include a static guaranteed reserved bandwidth and a dynamically guaranteed reserved bandwidth. The static guaranteed reserved bandwidth includes a specified service flowing from one port to another when the service is created, and the dynamically guaranteed reserved bandwidth includes service creation. When the service is generated according to the protocol, it flows from one port to another port, and the peak reserved bandwidth includes the maximum bandwidth that the service flows through.

The following is an example. Take an Ethernet physical port as an example. Assume that the available bandwidth of the physical port (that is, the port rate) is 1000M. You can set the first preset time range from 00:00 to 11:59. The bandwidth reservation parameters configured in the time range include: static guaranteed reserved bandwidth can be set to 100M, dynamic guaranteed reserved bandwidth can be set to 80M, peak reserved bandwidth can be set to 200M, and port convergence ratio can be set to 80%; The second preset time period is from 12:00 to 23:59, and the bandwidth reservation parameters configured in the time period include: static guaranteed reserved bandwidth can be set to 200M, dynamic guaranteed reserved bandwidth can be set to 100M, peak The reserved bandwidth can be set to 300M, and the port convergence ratio can be set to 80%. At this time, in the two different time periods, two different bandwidth reservation configurations are provided, wherein the bandwidth reservation in the second preset time period requires bandwidth reservation than the first preset time period. many.

The determining module 200 is configured to determine whether the bandwidth reservation meets a preset condition in each preset time period;

After the bandwidth reservation parameter of the port configured by the port bandwidth reservation configuration unit, the determination module 200 needs to preset the time period and the bandwidth reservation is not generated in each preset time period. The bandwidth reservation corresponding to the preset time period performs a first check; and in order to ensure that the service is in use, the current service does not conflict with the allocation of the bandwidth reservation in each preset time period, and is determined. The module 200 needs to perform a second check on the preset time period and the bandwidth reservation corresponding to the preset time period to determine whether the preset condition is met. The preset condition may include a first check condition and a second check condition.

The first determining module 200 is configured to perform a first check on the port bandwidth reservation check unit. If the first check is unsuccessful, the bandwidth reservation check configuration failure information of the port is prompted, that is, in each preset time period. The inner bandwidth reservation does not satisfy the first check condition; if the first check succeeds, the second check is performed by the service bandwidth reservation check unit. When the second check is unsuccessful, the bandwidth reservation check configuration of the service fails, that is, the bandwidth reservation does not satisfy the second check condition in each preset time period; when the second check succeeds, it is determined that The bandwidth reservation meets the preset condition in each preset time period.

The storage module 300 is configured to store each preset time period in association with the corresponding bandwidth reservation when the bandwidth reservation meets the preset condition.

After the second verification succeeds, it indicates that the reserved bandwidth configuration of the port does not conflict with the current service, that is, the bandwidth reservation meets the preset condition, and the storage module 300 uses the port bandwidth reservation configuration to save the unit. The time period is associated with the corresponding bandwidth reservation for storage; if the bandwidth reservation does not meet the preset condition, if the second verification fails, the bandwidth reservation configuration is not saved.

Optionally, the storage module 300 is further configured to reserve the bandwidth as a real-time bandwidth reservation if the bandwidth reservation parameter does not include the preset time period. It should be noted that if the bandwidth reservation parameter of the port configured by the port bandwidth reservation configuration unit is not configured with the preset time period, the bandwidth reservation defaults to all the time, that is, the bandwidth reservation is reserved as the real-time bandwidth. .

In the embodiment of the present invention, the user configures the preset time period of the port and the bandwidth corresponding to the preset time period, and the bandwidth reservation satisfies the first check condition and the second check in each preset time period. Each preset time period is associated with a corresponding bandwidth reservation in a preset condition such as a condition. The user can perform bandwidth reservation configuration for different time periods, meets the requirement that the service required by the user has a guaranteed bandwidth within a preset time period, and improves the utilization of the broadband.

Optionally, as shown in FIG. 4, based on the foregoing embodiment, the foregoing determining module 200 in this embodiment may include:

The first determining unit 210 is configured to determine, in each of the preset time periods, whether the sum of all static guaranteed reserved bandwidths of the port and all dynamic guaranteed reserved bandwidths is less than or equal to the available bandwidth of the port, and the port Whether the peak reserved bandwidth is greater than or equal to the sum of all static guaranteed reserved bandwidths of the ports and all dynamic guaranteed reserved bandwidths;

After the bandwidth reservation is configured in each preset time period, the first determining unit 210 needs to pass the port bandwidth reservation check unit to ensure that the bandwidth reservation is not generated in each time period. The first check is performed with the reserved parameters of the port, that is, all the preset time periods and the bandwidth reservation corresponding to the preset time period are uniformly verified, and the bandwidth reservation allocation is required in each time period. There is no conflict. The first check condition for port check bandwidth reservation may be: for each preset time period, for all ports: all static guaranteed reserved bandwidth plus all dynamic guaranteed reserved bandwidth is less than or equal to the available port. Bandwidth; at the same time, the peak reserved bandwidth of the port is greater than or equal to all static guaranteed reserved bandwidth of the port plus all dynamic guaranteed reserved bandwidth. If the first check condition is met, the first check succeeds, and the port bandwidth reservation check unit sends the bandwidth reservation parameter of the port to the service configuration unit. On the other hand, if the first check condition is not met, the first check fails, and the bandwidth reservation check configuration failure information of the return port is returned. The user can re-configure the bandwidth reservation parameters according to the information.

The second determining unit 220 is configured to: if the sum of all the static guaranteed reserved bandwidths of the ports and all the dynamic guaranteed reserved bandwidths is less than or equal to the available bandwidth of the ports, and the peak reserved bandwidth of the ports is greater than or equal to all the ports If the sum of the static guaranteed reserved bandwidth and all the dynamic guaranteed reserved bandwidths is determined, it is determined whether the product of the guaranteed bandwidth of all services passing through the port and the port convergence ratio is less than or equal to the port in each preset time period. The sum of all static guaranteed reserved bandwidths and all dynamic guaranteed reserved bandwidths;

After the first verification of the bandwidth reservation in each time period is successful, in order to ensure that the service is in use, the current service and the bandwidth reservation allocation in each time period are not generated. In the service creation process, the service configuration unit needs to allocate bandwidth for the service, and the second determining unit 220 performs a second check on the bandwidth reservation parameter of the port forwarded by the service configuration unit by using the service bandwidth reservation check unit. .

Optionally, the second determining unit 220 needs to compare the preset time period requirement of the bandwidth and the bandwidth of the service with the bandwidth reservation and the preset time period of the port, and requires the bandwidth reservation configuration of all the services of the port and the pre-requisite Set the time period to match the bandwidth reservation of the port and the configuration of the preset time period. The second verification condition of the bandwidth usage reservation of the verification service may be set as: in each preset time period, the sum of the guaranteed bandwidths of all services passing the configured port multiplied by the port convergence ratio is less than or equal to the port The sum of all static guaranteed reserved bandwidths plus all dynamic guaranteed reserved bandwidths. If the port has been configured with traffic before the bandwidth reservation parameter of the port is configured, you need to directly send the configured parameters to the service bandwidth reservation check unit for verification.

The following is an example. Assume that the port has been configured with three services in the time range of 00:00 to 11:59. The guaranteed bandwidth of the three services is 100M, and the bandwidth reservation parameters configured in the time range are as follows. Consistent. In this time period, the sum of the guaranteed bandwidths of the three services is 3*100M=300M. At this time, the guaranteed bandwidth of the service 300M* port convergence ratio is 80%=240M is greater than the static guaranteed reserved bandwidth of the port 100M and dynamic guarantee. Reserve a bandwidth of 80M. At this time, there is already a period of time that does not meet the condition, and there is no need to check the time period from 12:00 to 23:59. Therefore, the reserved bandwidth configuration of the port is in conflict with the current service. The failure, that is, the second verification failure, needs to return to the user related configuration failure information, that is, the bandwidth reservation configuration failure information of the returned service. If the time range is from 00:00 to 11:59, the port is only configured one time. For a service, the guaranteed bandwidth of the service is 100M. In this time period, the guaranteed bandwidth of the service 100M* port convergence ratio is 80%=80M, which is smaller than the sum of the static guaranteed reserved bandwidth of the port 100M and the dynamic guaranteed reserved bandwidth of 80M. During the time period from 12:00 to 23:59, the guaranteed bandwidth of the service 100M* port convergence ratio is 80%=80M, which is smaller than the sum of the static guaranteed reserved bandwidth 200M of the port and the dynamic guaranteed reserved bandwidth 100M. At this time, the reserved bandwidth configuration of the port is not in conflict with the current service. In this case, the configuration succeeds, that is, the second verification succeeds.

The determining unit 230 is configured to: if the product of the guaranteed bandwidth sum of all services passing through the port and the port convergence ratio is less than or equal to the sum of all static guaranteed reserved bandwidths of the port and all dynamic guaranteed reserved bandwidths, then each pre- Set the bandwidth reservation within the time period to meet the preset conditions.

In this embodiment, when the first check and the second check are successful for the bandwidth reservation in each preset time period, the determining unit 230 determines that the bandwidth reservation meets the pre-predetermined time period. Set conditions.

Optionally, based on the foregoing embodiment, in the embodiment, the storage module 300 is further configured to ensure that all services passing through the port are guaranteed in each preset time period when a new service is added to the current service of the port. The product of the bandwidth sum and the port convergence ratio is greater than the sum of all the static guaranteed reserved bandwidths of the ports and all the dynamic guaranteed reserved bandwidths, and the bandwidth reservation configuration failure information of the service is prompted.

Optionally, after the storage module 300 associates each preset time period that meets the preset condition with the corresponding bandwidth reservation, after the service of the port is used in the bandwidth reservation parameter, when When the service is added to the current service of the port, the second verification is required. When the product of the guaranteed bandwidth of all services passing through the port and the port convergence ratio is greater than the sum of all the static guaranteed reserved bandwidths of the ports and all the dynamic guaranteed reserved bandwidths, the reserved bandwidth configuration of the port and the service at this time There is a conflict, the second verification is unsuccessful, and the bandwidth reservation configuration failure information of the returned service is returned.

Assume that the current service of the port is 2, and the guaranteed bandwidth of the two services is 100 M. The bandwidth reservation parameters configured in the time range are consistent with the above. In this time period, the sum of the guaranteed bandwidths of the two services is 2*100M=200M. At this time, the guaranteed bandwidth of the service 200M* port convergence ratio is 80%=160M, which is smaller than the static guaranteed reserved bandwidth of the port 100M and dynamic guarantee. Reserve a bandwidth of 80M. However, if you create a new one based on the current business at this time For a service with a guaranteed bandwidth of 100 M, the guaranteed bandwidth of the service 300 M* port convergence ratio is 80% = 240 M is less than the sum of the static guaranteed reserved bandwidth 100 M of the port and the dynamic guaranteed reserved bandwidth 80 M. At this time, there is already a time period that does not satisfy the condition, and it is not necessary to check the time period from 12:00 to 23:59. Therefore, the reserved bandwidth configuration of the port is in conflict with the current service. In this case, the configuration fails, that is, the second verification fails, and the bandwidth reservation configuration failure information of the service is returned.
