technical field

Background technique

As the architecture evolves, traditional network element equipment also evolves from specialization to generalization.

With the continuous emergence of various Internet services, the requirements for the number of user sessions supported by a broadband network gateway (BNG) device continue to increase, and the requirements for the ability of the BNG device to provide services open to the outside world are also higher. As a traditional broadband access gateway device, the BNG device can realize the two decoupling problems mentioned above based on the SDN/NFV architecture.

However, the same BNG device not only functions as a user access device, but also forwards the user, so that the BNG device cannot solve the problem of decoupling the user's online and forwarding. However, since the detection and keep-alive function of the user terminal needs to be implemented on the current user plane (UP) device, when the UP device fails or the load is unbalanced, etc., the control plane (CP) device needs to The user terminals on the UP device perform balanced adjustment. For example, the CP device migrates some user terminals from the faulty UP device to another UP device.

This leads to problems such as disconnection of the user terminal.

Detailed ways

The embodiments of the present application provide a user access processing method and related equipment, which are used to directly implement the probe response processing to the user terminal in the AGW device, without the need to implement the probe response of the user terminal through the UP device, and can achieve higher quality It completes the process of going online, detecting, and renewing the lease of the user terminal, avoiding the situation that the user terminal is disconnected during any migration scenario.

The technical solutions in the present application will be described in detail below with reference to the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It is to be understood that data so used may be interchanged under appropriate circumstances so that the embodiments described herein can be practiced in sequences other than those illustrated or described herein.

With the development of software-defined network technology and network function virtualization technology, the metropolitan area network has changed from the traditional network-centric architecture to the data center-centric architecture; the traditional network element equipment has also changed from specialization to generalization In the process of evolution, network element equipment needs to solve two decouplings in the process of evolving towards generalization: the decoupling of control and forwarding, and the decoupling of software and hardware. Among them, the result of control and forwarding can also be called CU separation, that is, the network architecture in which the CP device and the UP device are decoupled. The implementation of the CU separation can be implemented in the following ways:

The first implementation method: the control plane and the forwarding plane are located on different hardware devices.

That is, it is understood that the CP device and the UP device are two separate and different devices. Optionally, the CP device and the UP device are distributed in different locations. For example, the CP device is located in the data center of the cloud, and the UP device is deployed in a suitable location in the network according to the requirements. In this way, the deployment of the control plane and the forwarding plane is more flexible.

The second implementation mode: the control plane and the forwarding plane are located on the same hardware device and have separate functions.

In this implementation manner, the physical entity of the CP device and the physical entity of the UP device are the same device. For example, the CP device and the UP device run in the same host, the same server or the same terminal.

It can be understood that, the above-mentioned CP device and UP device are both implemented through virtualization technology. The CP device is called, for example, a virtual CP (virtual CP, vCP), and the UP device is called, for example, a virtual UP (virtual UP, vUP). For example, the CP device is a virtual machine, and the UP device is a virtual router or virtual switch. In an example, both the CP device and the UP device are implemented based on a general physical server combined with the NFV technology, and the CP device and the UP device are two different virtualized network functions (VNFs). For example, both the CP device and the UP device are network elements virtualized through the X86 server.

In another example, the CP device is implemented by a virtualization technology, and the UP device is implemented by a traditional network device. The UP device is called, for example, a physical UP (physical UP, pUP).

This embodiment does not limit the number of UP devices in the communication system. Optionally, the CU-separated communication system includes multiple UP devices. Optionally, a plurality of UP devices are distributed in different locations in the communication system where the CU is separated. Optionally, multiple UP devices in a communication system where CUs are separated cooperate to share forwarding tasks based on a distributed architecture.

It's worth stating that "CU separation" can have different names. For example, different standards, different versions of the same standard, different manufacturers, and different application scenarios may have different names for "CU separation". For example, the term CU separation" may also sometimes be referred to as "control and forwarding separation", "forwarding control separation", "control plane and user plane separation", "control and user separation", etc. Additionally, "CP" may have different For example, different standards, different versions of the same standard, different manufacturers, and different application scenarios can have different names for "CP". For example, the term "CP" can sometimes be called "CP function (CPF)" " or "CP plane". "CP", "CPF" and "CP plane" are used interchangeably herein. The term "CP device" refers to any device that implements CP functionality. Furthermore, "UP" may also have Different names. For example, different standards, different versions of the same standard, different manufacturers, and different application scenarios can have different names for "UP". For example, the term "UP" can sometimes be called "UP function (UP function, UPF)" or "UP plane". "UP", "UPF" and "UP plane" are used interchangeably herein. The term "UP device" refers to any device that implements UP functionality.

As a traditional broadband access gateway device, BNG equipment implements functions such as user authentication, access control, and traffic scheduling in user broadband access services. With the continuous emergence of various Internet services, the number of user sessions supported by BNG is required. With the continuous improvement, the requirements for the continuous improvement of user access bandwidth, especially the ability of the BNG system to provide open and programmable services to the outside world, are also getting higher and higher. In view of these requirements, in the architecture based on software-defined network technology and network function virtualization technology, traditional BNG devices are decoupled from control and forwarding, and software and hardware are decoupled to form a CU-separated BNG system. The CU-separated BNG system extracts and concentrates the user management functions on multiple BNG devices to form CP devices. The BNG devices retain routing and forwarding functions to form UP devices.

On the basis of maintaining the original functions of BNG, the CU-separated BNG system has the advantages brought by the CU-separated architecture. For example, a BNG system separated by a CU can have multiple UP devices, and the CP device schedules multiple UP devices to process traffic forwarding tasks, and the CP device allocates resources to multiple UP devices. The utilization and reliability of the equipment of the BNG system under the separation architecture can be greatly improved. It should be noted that, in this embodiment of the present application, the "BNG system with CU separation" may have different names. For example, different standards, different versions of the same standard, different manufacturers, and different application scenarios may have different names for the "BNG system with CU separation". For example, the term "CU-disaggregated BNG system" may also sometimes be referred to as "disaggregated BNG system (DBNG)", and correspondingly, CP devices in a CU-disaggregated BNG system may be referred to as DBNG-CP, CU The UP device in the separate BNG system may be referred to as DBNG-UP. For another example, the term "CU-disaggregated BNG system" may sometimes also be referred to as "virtual broadband network gateway (virtual BNG, vBNG) control plane and user plane disaggregated system (control plane and user plane disaggregated system, CU system)", that is "vBNG CU system", correspondingly, the CP device in the CU-separated BNG system may be referred to as vBNG-CP, and the UP device in the CU-separated BNG system may be referred to as vBNG-UP. For another example, the term "CU-separated BNG system" may also sometimes be referred to as "virtual broadband remote access server (vBRAS) CU system", that is, "vBRAS CU system", correspondingly, the CU-separated BNG The CP device in the system may be referred to as vBRAS-CP, and the UP device in the CU-separated BNG system may be referred to as vBRAS-UP. "DBNG", "vBNGCU system" and "vBRAS CU system" are used interchangeably herein.

Under the CU separation architecture, the BNG device, as a traditional broadband access gateway device, can realize the two decoupling problems mentioned above based on the SDN/NFV architecture. However, the same BNG device not only functions as a user access device, but also forwards the user, so that the BNG device cannot solve the problem of decoupling the user's online and forwarding. And because the detection and keep-alive function of the user terminal needs to be implemented on the current UP device, when the UP device fails or the load is unbalanced, etc., the CP device needs to balance the adjustment of the user terminals on the UP device, such as: CP device Migrate some user terminals from the faulty UP device to another UP device.

During the migration process, if there is no user forwarding table entry of the user terminal on the new UP device, the new UP device cannot complete the detection and response function of the user terminal, and it needs to wait for the CP device to forward the user forwarding table. After the entry is delivered to the new UP device, the new UP device can complete the corresponding probe response based on the user forwarding entry of the user terminal. Obviously, before the CP device has not issued the user forwarding entry of the user terminal to the new UP device, the user terminal will be disconnected because the corresponding probe response cannot be obtained.

For example, the CP device performs online scheduling on the user terminal, as shown in FIG. 1 or FIG. 2 . FIG. 1 shows a schematic diagram of migrating a user terminal, and FIG. 2 shows another schematic diagram of migrating a user terminal. As can be seen from Figure 1, the interface in UP device 1 (UP1) is connected to user terminal 1 (User 1), the interface in UP2 is connected to User 2, and the interface in UP 3 is connected to User 3; Due to the overload of the interface, the connection of User 1 fails (the gray part in Figure 1). At this time, the CP device that can perform user scheduling and migration between UP1, UP2 and UP3 can migrate User1 in UP1 to UP2 or UP3 (for example: Figure 1 shows the migration of User 1 to UP2). However, if the CP has not delivered the user forwarding entry of User 1 to UP2, User 1 cannot access UP2 normally, so that UP2 cannot respond to the probe of User 1, which further causes User 1 to be disconnected.

Likewise, FIG. 2 shows a process of implementing user migration based on user groups. As can be seen from Figure 2, the interface in UP1 is connected to user group 1, and user group 1 can include User 1; the interface in UP2 is connected to user group 2 and user group 4, and user group 2 can include User 2, user Group 4 may include User 4; the interface in UP 3 is connected to User Group 3, and User Group 3 may include User 3. If the interface of UP2 is overloaded at this time (the gray part shown in Figure 2), the CP device can migrate user group 2 or user group 4 in UP2 to UP1 or UP3 (for example: Figure 2 shows the Migrate user group 4 to UP1). However, if the CP has not issued the user forwarding entry of the user group 4 to the UP1, the user group 4 cannot access the UP1 normally, so that the UP1 cannot respond to the probe of the user group 4, resulting in the user group 4 You need to go offline to dial to reconnect.

It can be understood that the interface that the CP device described above can schedule the UP device may include, but is not limited to: a control packet redirect interface (control packet redirect interface, CPRi), a management interface (management interface, Mi) and a control interface (state control interface, SCi), which is also not limited in the embodiments of the present application.

Based on this, in order to solve the above problems, an embodiment of the present application provides a new network architecture diagram for user access. As shown in FIG. 3 , the communication system includes at least one UP device and a CP device, and in the communication system Add an access gateway (AGW) device. The AGW device establishes a Layer 2 tunnel with at least one UP device through a metro edge router (MER), and interconnects with each UP device, for example, establishes a Layer 2 tunnel with pUP1, pUP2, and vUP3. The AGW device can receive the request sent by the user terminal, and intercept the probe request in the request, so as to realize the response to the probe keep-alive message in the probe request. In addition, the AGW device can also transmit the access request in the request to the CP device through at least one UP device, so that the CP device can process the user dialing protocol message in the access request and dial the remote user. The remote authenticationdial In user service (RADIUS) interacts with the user authentication server, and performs user authentication, authorization, and accounting based on the interaction of the service server. When the user passes the authentication, the CP device can forward user entries and user detection. The table entry and other information are delivered to the corresponding UP. After receiving the user forwarding entry sent by the CP device, the UP device generates the user's forwarding entry locally according to the user's forwarding entry, and then executes related service policies and traffic flow. Forwarding and publishing routes to the outside world.

In addition, the AGW device can also directly monitor the network status of the user terminal, and when the network status of the user terminal is abnormal or the detection fails during the process of detecting and keeping the user terminal, it can directly report the detection failure and other information to the CP device, so that the CP The device can perform processing such as offline of the user terminal.

It can be understood that the pUP1, pUP2 and vUP3 described in the above Figure 3 can be backup UP devices for each other, that is, the pUP1, pUP2 and vUP3 can backup each other and share the traffic corresponding to the network through load sharing. However, it should be understood that, in practical applications, other UP devices such as pUP4, pUP5, or vUP6 may also be included, which are not specifically described in the embodiments of the present application. In addition, the user terminal described above may be a device such as a mobile terminal, a personal computer, and an intelligent terminal, which is not specifically described in the embodiments of the present application.

Furthermore, the embodiment of the present application also provides another schematic diagram of a network architecture for user access. As shown in FIG. 4 , an AGW management module may be added to a virtual subscriber control unit (vSCU), so that the AGW management module can be used as a user's dial-up and online network element and a detection and keep-alive network element. User authentication and accounting are performed on the user terminal dialing from the AGW device to the CP device side. After authorization, etc., the CP device will send the user detection entry to the AGW device, the AGW device will actively detect the user terminal, and report the user's keep-alive status to the CP device side. At the same time, the AGW device is also responsible for the active detection of the user terminal. answer.

Based on the network architecture provided in FIG. 3 or FIG. 4 , FIG. 5 is a schematic flowchart of a method for user access processing provided by an embodiment of the present application. As shown in FIG. 5 , the method includes the following steps:

501. A user terminal sends a first request to an AGW device, where the first request includes a probe request and an access request.

When the user needs to access the network, the user terminal may first send a first request to the AGW device, where the first request may include a probe request and an access request. In this way, the AGW device can intercept the probe request, so that after receiving the user probe entry sent by the CP device, it can directly perform probe response processing on the user terminal. Moreover, the AGW device may also send the access request to the CP device through at least one UP device, where the access request includes a user protocol dial-up message. Exemplarily, in the network scenario shown in FIG. 3 or FIG. 4 , the user terminal sends the first request, and the AGW device connected to the user terminal in the network broadcasts the access request corresponding to the user terminal to the user terminal through the Layer 2 network. At least one UP device, so that each UP device receives the access request, and each UP device sends the access request to the CP device.

502. The AGW device sends an access request to the CP device through at least one UP device.

In the embodiment, the CP device can receive the access request sent by the AGW device through at least one UP device, so as to respond to the access request, and process the access request, for example: determine a specific access policy and implement user authentication. Wait.

503. The CP device sends a user detection entry to the AGW device.

In the embodiment, after receiving the access request sent by the AGW device, the CP device performs user authentication, charging and authorization by interacting with the service server. After the user terminal corresponding to the access request is authenticated, the CP device can generate a user detection entry, and directly send the user detection entry to the AGW device, so that the AGW device can identify the user detection entry that needs to be accessed based on the user detection entry. The user terminal of the network responds to the probe. Specifically, the foregoing user detection table entries may include but are not limited to: user interface, user virtual local area network (VLAN), user internet protocol (IP), user media access control (MAC) ), user gateway IP or user gateway MAC, etc., which can be used to identify a series of parameters of the user terminal, which are not specifically described here.

504. The AGW device performs probe response processing on the probe request based on the user probe entry.

In the embodiment, after receiving the user detection entry directly sent by the CP device, the AGW device may send a detection response to the user terminal that needs to access the network based on the user detection entry. For example, a probe response to the first user terminal is implemented through the user probe entry.

Through the above method, the CP device can directly realize the detection response to the user terminal that needs to access the network in the AGW device without sending the user forwarding entry to the UP device, avoiding that the UP device has not yet received the user forwarding. The user terminal is disconnected due to the publication of the item, which can ensure the stable access of the user terminal.

It can be understood that, in other embodiments, if a certain UP device fails, it is obvious that the user terminal connected to the failed UP device cannot forward traffic. Therefore, based on the description in FIG. 5 above, please refer to FIG. 6 , which is a schematic flowchart of another method for user access processing provided in this embodiment of the present application, as shown in FIG. 6 :

603. The CP device sends a user detection entry to the AGW device.

604. The AGW device performs probe response processing on the probe request based on the user probe entry.

It should be understood that the described steps 601 - 604 can be understood with reference to the steps 501 - 504 described in FIG. 5 , and details are not repeated here.

605. The CP device determines a first UP device, where the first UP device is one or more of at least one UP device.

In the embodiment, after the CP device receives the above-mentioned access request and enters the steady state access, if a certain UP device fails, for example: the second UP device; then the CP device can first determine that each UP device corresponds to Then, according to the load situation of each UP device, an appropriate UP device is selected to respond to the forwarding traffic of the user terminal on the faulty UP device.

It can be understood that the load situation of the first UP device may be better than the load situation of other UP devices, for example: the first UP device has been running the least amount of business lines, etc.; and the first UP device may be at least one UP device. one or more of the devices. For example: when the load of a certain UP device is too heavy, the CP device can determine the load of each UP device to determine the first UP device with a lighter load, so as to make the UP device with an excessively heavy load The user terminal on the UP device can be migrated to the first UP device, so as to respond to the forwarding traffic of the user terminal on the UP device with heavy load through the first UP device.

Exemplarily, the CP device may obtain the authorized service level agreement (SLA) type information, and then determine the first UP device based on the preconfigured policy and the authorized SLA type information. It can be understood that the described authorized SLA type information can be used to reflect the load condition of each UP device in the at least one UP device, or to reflect the quality attribute of the user terminal in each UP device.

In other embodiments, the CP device may also send a request to a universal storage flash (USF) device, and after receiving the request, the USF device determines based on the authorized SLA type information stored in the internal storage and a pre-configured policy Take out the first UP device. In this way, the USF device can feed back the relevant identifier of the first UP device to the CP device, so that the CP device can identify the at least one UP device as a suitable first UP device. It can be understood that the implementation manner of the CP device to determine the first UP device is not limited in the embodiments of the present application, and the first UP device may also be determined based on other methods in practical applications, which is not limited here.

When there is a load condition of the first UP device that is better than the load condition of the UP device when the migration needs to be performed, the CP device determines to use the first UP device as the target UP device for responding to users on the UP device due to the failure The forwarding traffic of the terminal. However, when the load conditions of multiple first UP devices are higher than the load conditions of the UP devices that need to be migrated, the CP device determines to randomly select one or more UP devices from the multiple first UP devices as the target UP device, The user terminals on the UP device with heavy load are randomly migrated to one or more first UP devices, so that the CP device can respond to the forwarding traffic of the user terminals on the UP device due to the failure.

606. The CP device sends a user forwarding entry to the first UP device, where the user forwarding entry includes a user virtual MAC, and the user virtual MAC is used to identify the first user terminal corresponding to the second UP device, and the load of the first UP device. The situation is better than the load situation of the second UP device, and the second UP device is any one of the at least one UP device.

In this embodiment, the second CP device can be understood as those UP devices that are faulty, or the UP devices that are under heavy load and cause the connected first user terminal to go offline, or the like. Since the user forwarding entry is a forwarding entry corresponding to the first user terminal on the second UP device, the user forwarding entry may include the user virtual MAC, and the user virtual MAC corresponds to a user terminal on the second UP device. virtual MAC address, and the corresponding virtual MAC address can be used as the Layer 3 gateway MAC of the first user terminal connected to the second UP device, so the user virtual MAC can be used to identify the first user terminal corresponding to the second UP device; In addition, the IP address segment to which the IP address of the first user terminal connected to the second UP device belongs is in a one-to-one correspondence with the above-mentioned user virtual MAC. Therefore, after the CP device determines the first UP device, it can send the user forwarding entry of the first user terminal corresponding to the second UP device to the first UP device, so that the CP device can pass the first UP device. In response to the forwarding traffic of the first user terminal, etc. It should be understood that the described first user terminal connected to the second UP device may be one or more of the user terminals that send the access request.

607. The CP device migrates the user virtual MAC to the first UP device.

In the embodiment, when the first user terminal on the second UP device fails, or the connected first user terminal cannot access the network due to the load of the second UP device, the CP device needs to perform the second UP device on the second UP device. The first user terminal on the device is migrated to the first UP device, so that the first UP device can respond to forwarding traffic and the like of the first user terminal. Specifically, the CP device needs to migrate the user virtual MAC from the second UP device to the first UP device.

Exemplarily, for the way that the CP device migrates the user virtual MAC to the first UP device, the following methods can be used:

The first implementation manner: the CP device migrates the user virtual MAC to the first UP device based on the routing address corresponding to the second UP device, and migrates the routing address corresponding to the second UP device to the first UP device, wherein the second UP device The routing address corresponding to the UP device corresponds to the user virtual MAC. That is to say, it can be understood that the routing address corresponding to the second UP device can correspond to a user virtual MAC as a whole, so that the CP device can migrate the user virtual MAC to the user terminal based on the routing address corresponding to the second UP device when migrating the user terminal. The first UP device and the routing address corresponding to the second UP device are also migrated to the first UP device, specifically, the user virtual MAC is directed to the tunnel of the first UP device. The described tunnels may include but are not limited to SRV6, virtual extensible local area network (virtual extensible local area network, VxLAN), etc., which are not specifically limited.

When multiple first user terminals are connected to the second UP device, in order to be able to migrate the multiple first user terminals in the second UP device to different first UP devices in a decentralized manner, a certain first UP can be reduced. equipment load. Therefore, in the second implementation manner, the CP device may further segment the routing address corresponding to the second UP device to obtain at least one segment of the route address, wherein each segment of the route address corresponds to a user virtual MAC; then, the CP device The corresponding user virtual MAC is migrated to the corresponding first UP device based on each segment of the routing address. Similarly, the CP device also needs to migrate to the first UP device together with the routing address corresponding to the second UP device.

It can be understood that, in addition to the above-mentioned two ways, the above-mentioned migration modes of the CP device may also be other migration modes in practical applications, which are not specifically described in the embodiments of the present application.

608. The CP device sends a first message to the AGW device, where the first message includes the user virtual MAC.

609. The AGW device migrates the forwarding traffic of the first user terminal corresponding to the user virtual MAC to the first UP device.

In the embodiment, after the CP device migrates the first user terminal in the second UP device to the first UP device by migrating the user virtual MAC and routing address, the CP device can send the first message to the AGW device. Then, after the AGW device receives the first message, it parses out the user virtual MAC carried in the first message, so that the AGW device can migrate the forwarding traffic of the first user terminal corresponding to the user virtual MAC to the first user terminal. A UP device. In this way, the first user terminal can implement normal traffic forwarding and the like through the first UP device, so as to complete procedures such as lease renewal.

It can be understood that the CP device may send the first message to the AGW device through the first UP device.

Optionally, 610, the AGW device monitors the network status of the user terminal.

Optionally, 611. When the network state of the user terminal is in a disconnected state, the AGW device sends a second message to the CP device.

In the embodiment, the AGW device can also actively monitor the network state of the user terminal, and when the network state of the user terminal is in the disconnected state, it indicates that the AGW device fails to detect the detection response based on the user detection table entry, then it needs to The AGW device can feed back relevant conditions such as detection failure to the CP device, so that the CP device can perform processing such as offline of the user terminal.

Optionally, 612, the CP device performs offline processing on the user terminal based on the second message.

It can be understood that, in other embodiments, the CP device may also send a session addition request or a session deletion request to the first UP device, and may also send a session addition request or a session deletion request to the AGW device.

In the embodiment of the present application, after the AGW device receives the probe request and receives the user probe entry sent by the CP device, the probe response processing to the user terminal can be directly implemented in the AGW device, and the detection of the user terminal does not need to be implemented through the UP device. Response, can complete the process of user terminal online, detection, lease renewal, etc. with higher quality, avoiding the situation that the user terminal is disconnected in any migration scenario; in addition, the AGW device sends an access request to the CP After determining the first UP device, the CP device can migrate the user terminal in the fault scenario from the overloaded second UP device to the first UP device, so that the first UP device can better complete the user terminal.
