Description

A fault detection method and device

technical field

The embodiments of the present invention relate to the communication field, and in particular, to a fault detection method and device.

Background technique

In the field of communication, in order to ensure the quality of data transmission between network devices, it is necessary to quickly detect communication failures between network devices, so as to establish a new communication link in time when a failure occurs, or switch to other communication links. . At present, a bidirectional fault detection (Bidirectional Forwarding Detection, BFD for short) method is a most widely used network fault detection technology. The characteristics of BFD are: light load, short duration, and it can quickly implement any type of communication link, such as direct physical link, virtual circuit, multi-hop routing channel, etc.

After a BFD session is established, both parties in the BFD session periodically send BFD packets to the peer end on the session channel. At the same time, they also periodically check the BFD packets sent by the peer end on the session channel. If no BFD packet is received from the peer within the detection time, it is determined that the communication link between the two parties in the BFD session is faulty.

FIG. 1 shows a schematic diagram of a typical data center network architecture in the prior art. As shown in Figure 1, the data center network includes multiple virtual machines (Virtual Machines, referred to as VMs) for forwarding data. Multiple virtual machines are connected to Layer 2 devices, and multiple Layer 2 devices are connected to multiple Layer 3 devices. A layer-2 device can be a router, and a layer-3 device can be a switch, that is, multiple virtual machines are connected to one router through a switch, and multiple routers can also be connected to multiple virtual machines through a switch. In the existing technology, in order to ensure the reliability of data transmission, it is necessary to send detection packets between each device to detect whether a link is faulty, such as sending a BFD packet between a virtual machine and a router, and through the detection packet After a link or device failure is detected, the replacement of the link or device can be triggered to ensure the reliability of data transmission and reduce the interruption time of data transmission.

In the prior art, BFD packets are usually sent periodically between devices, and the period is millisecond level, such as 10ms. At this time, a virtual machine needs to send 100 BFD packets within 1 second. Furthermore, because multiple VMs are connected to a router through a switch, at this time, the BFD that the router needs to process within 1 second will reach the level of 10kpps, which is far beyond the capabilities of ordinary routers. When ordinary routers process data through the CPU, they can usually only Reach the 1kpps level. It can be seen that the periodic sending of BFD packets by the device will increase the load on the network and increase the network overhead.

detailed description

In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the following, the basic concepts involved in the embodiments of the present invention are introduced for ease of understanding.

The term "user equipment" includes, but is not limited to, handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment (User Equipment, referred to as UE), Mobile station (Mobile station, MS for short), user equipment (terminal), user equipment equipment (Terminal Equipment) and so on. For convenience of description, in this application, it is referred to as user equipment for short.

The term "first device" or "second device" is a processing device with a wireless communication function, and is used to transmit data sent by the user equipment. The first device and/or the second device include, but are not limited to, devices such as a switch, a router, a soft switch, and an Internet Protocol Multimedia Subsystem (Internet Protocol Multimedia Subsystem, IMS for short).

The term "service data" may also be referred to as "user data", and may include various types, such as media streams transmitted between user equipments through a transmission link after a service connection is successfully established. Specifically, the media stream data may be video data, voice data, short message data, and so on. If the media stream data is interrupted, it will have a great impact on the user, and the user experience is poor. Therefore, the method provided by the embodiment of the present invention is in the service connection state, that is, the stage where the media stream can be normally transmitted between user equipment. If it is detected that the media stream is suddenly interrupted, the frequency of sending fault detection packets is increased, so as to quickly detect the faulty interface.

In the specific implementation, before the business connection is successfully established, the media stream data will not be transmitted between the user equipment and the network, and some control plane signaling for establishing the business connection may be transmitted, and then through the signaling interaction of these control planes, the network is successfully established. A session (session) on the media plane means that a service connection is established successfully, after which media stream data can be transmitted between user equipments. Because when the business connection is not successfully established, the media stream data will not be transmitted between the user equipments, and only a small amount of control plane signaling for establishing the business connection is transmitted, and due to the interaction of the control plane signaling for establishing the business connection The process is very fast, so in the embodiment of the present invention, when the service connection is not successfully established, for example, in the process of establishing the service connection, it is enough to use a smaller sending frequency of the fault detection message, which saves signaling overhead and reduces network resource usage. consume.

The term "and/or" is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone. three conditions. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship.

The fault detection message in the embodiment of the present invention may be a message capable of detecting whether a device and a link between devices are faulty, including but not limited to BFD and Address Resolution Protocol (APR) messages.

The following uses the first device and the second device as examples to introduce the detection mechanism of BFD packets.

The first device and the second device negotiate through control signaling to negotiate the parameters of the BFD session, such as the session identifier, expected BFD packets received, the minimum time interval for sending BFD packets, and the status of the local BFD session. . The control signaling is encapsulated in UDP stripes for transmission. After the negotiation succeeds, a BFD session is established between the first device and the second device. Specifically, there are two ways.

Method 1: The first device periodically sends BFD packets to the second device, and the second device periodically sends BFD packets to the first device. If the first device does not receive the BFD packet sent by the second device within a certain period of time, then It is assumed that the second device and/or the link between the first device and the second device has failed. The failure of the link between the first device and the second device may specifically include the first device, the second device, the transmission device on the link between the first device and the second device, and the first device and the second device failure of any one or more of the transmission lines in between. To meet the requirement of fast detection, the BFD protocol stipulates that the unit of sending interval and receiving interval of BFD packets is microseconds. However, limited by the current processing capabilities of existing technologies, the time interval for sending and receiving BFD packets configured by most manufacturers' devices is at the millisecond level.

Method 2: The first device periodically sends a BFD packet to the second device, and the second device sends the response of the BFD packet to the second device. If the first device does not receive the response sent by the second device within the preset time period , it is considered that the second device and/or the link between the first device and the second device has failed. The link between the first device and the second device may include a device between the first device and the second device, and a transmission line between the first device and the second device.

The ARP is used to realize the mapping between the Layer 3 Internet Protocol (Internet Protocol, IP for short) address and the Layer 2 Media Access Control (Medium Access Control, MAC for short) address in the Ethernet. ARP-related protocols are RFC826, RFC903, etc.

ARP is based on the principle that the MAC address corresponding to an IP address is queried by broadcasting in the same network segment of the Ethernet, so as to realize the dynamic mapping between the Layer 3 IP address and the Layer 2 MAC address. This is a protocol supported by any Ethernet host device, and it can also be called ARP as a layer 2.5 protocol.

The following uses the first device and the second device as examples to introduce the detection mechanism of the ARP packet.

The first device sends an APR request in a broadcast manner, and the target IP of the APR request is the IP of the second device. All Ethernet devices including the second device will receive the APR request, but only the second device among the Ethernet devices will respond to the APR request. The second device sends an ARP response message including the MAC address of the second device to the first device. After the first device receives the ARP response message, the first device can use the MAC address of the second device to communicate with the second device. communication. In this process, the first device successfully receives the APR response sent by the second device, that is, it determines that the second device is not faulty.

If it is determined in the above manner that a fault occurs on the second device or the link between the first device and the second device, the system will switch to the standby network in time to improve the reliability of data transmission.

Based on the above content, the system architecture applicable to the embodiment of the present invention is introduced below. Fig. 2 exemplarily shows a schematic diagram of a system architecture applicable to an embodiment of the present invention. As shown in FIG. 2 , it includes user equipment 201 used by user A, router 202 connected to the user equipment, router 202 connected to switch 203 and switch 204, switch 203 connected to switch 204, switch 203 and switch 204 connected to core network equipment 205 and The core network device 206 is connected between the core network device 205 and the core network device 206, the core network device 205 and the core network device 206 are connected to the switch 207 and the switch 208, the switch 207 is connected to the switch 208, and the switch 207 and the switch 208 are connected to the router 209. The router 209 connects the user equipment 210 of user B. Optionally, the user equipment in this embodiment of the present invention may be connected to multiple routers, and the router may also be connected to multiple user equipments. In a data center, core network devices are usually virtual machines.

Any one of the first device or the second device in the embodiment of the present invention may be any one of the aforementioned routers, switches, and core network devices, and the first device and the second device are two different devices. The fault detection device in the embodiment of the present invention may be installed in the first device, or in the second device, or one fault detection device is respectively installed in the first device and the second device. The data transmitted by the user equipment 201 can be transmitted to the user equipment 210 through multiple links. For example, a link connects the user equipment 201 to the router 202, the switch 203, the core network device 205, the switch 207, the router 209, and the user equipment 210. Assuming that the first device is a core network device 205, and the second device is a router 209, fault detection can be performed between the first device and the second device, and when it is detected that the link or a device on the link fails, Report to the upper-layer application and switch to the backup link. For example, it is detected that the switch 207 on the link between the second device and the first device is faulty. At this time, switch to a new link. For example, the user equipment 201 is connected to the router 202, Switch 203 , core network device 205 , switch 208 , router 209 , and user equipment 210 . In this way, the reliability of the system architecture can be improved.

Based on the above content and the system architecture shown in FIG. 2, FIG. 3 shows a schematic flowchart of a fault detection method provided by an embodiment of the present invention, as shown in FIG. 3, including:

Step 301, determining that no service connection has been established between the first device and all user equipment corresponding to the second device; wherein the service data of the user equipment corresponding to the second device is transmitted through the second device and the first device;

Step 302: Determine the frequency at which the first device sends the fault detection message, and when it is determined that the frequency at which the first device sends the fault detection message is not less than the first threshold, adjust the frequency at which the first device sends the fault detection message so that after adjustment The frequency at which the first device sends the fault detection message is less than the first threshold; and/or

Determine the frequency at which the second device sends the fault detection message; when determining that the frequency at which the second device sends the fault detection message is not less than the second threshold, adjust the frequency at which the second device sends the fault detection message so that the adjusted second The frequency at which the device sends fault detection packets is less than the second threshold. Optionally, the first threshold may be equal to the second threshold, or the first threshold and the second threshold may be dynamically determined according to a specific implementation environment, and the first threshold may be greater than or less than the second threshold.

In the above step 301, there are many ways to connect the user equipment corresponding to the second device to the first device and the second device, for example, the user equipment is connected to the second device through other devices, and the second device is connected to the first device through other devices , or the user equipment is directly connected to the second device, and the second device is directly connected to the first device. No matter how the user equipment corresponding to the second device is connected to the first device and the second device, the service data of the user equipment needs to be transmitted through the first device and the second device.

In the above step 301, establishing a service connection between the user equipment and the first device specifically means that the user equipment transmits a request to establish a service connection with another user equipment through the second device and the first device. After the service connection is successfully established, the user A service connection is successfully established between the device and the second device, the user equipment and the first device, and the user equipment and another user equipment, and communication can be performed through the successfully established service connection link, that is, service data can be transmitted.

In the embodiment of the present invention, there are many ways to determine the frequency of the first device sending the fault detection message. For example, by obtaining the parameters of the timer used to determine the frequency of the first device sending the fault detection message, the timer The time parameter of the device is changed, so as to achieve the purpose of adjusting the frequency of sending the fault detection message by the first device. To determine the frequency at which the second device sends the fault detection message, the parameters of the timer used to determine the frequency at which the second device sends the fault detection message can be obtained through transmission signaling, and the time parameter of the timer is changed to achieve adjustment The purpose of the frequency of sending the fault detection message by the second device. For example, if the preset time of the timer used to determine the frequency of sending the fault detection message by the first device is 10 milliseconds, then the first device sends a fault detection message every 10 milliseconds, and the time of the timer is set to 20 milliseconds, the first device sends a fault detection message every 20 milliseconds, so that the frequency of the first device to send a fault detection message is reduced.

In the above step 302, the frequency of the fault detection message sent by the first device to the second device can be changed, and the second device can respond after receiving the fault detection message. In this way, the frequency of the fault detection message sent by the first device If the frequency is reduced, the frequency of sending the response by the second device is also reduced, thus reducing data transmission and reducing network load.

Another implementation method is to change the frequency of the fault detection message sent by the second device to the first device, and the first device can respond after receiving the fault detection message. In this way, the fault detection message sent by the second device If the frequency of the first device is reduced, the frequency of sending the response by the first device is also reduced. Therefore, the data transmission is reduced and the network load is reduced.

The third way of implementation can be to change the frequency of the fault detection message sent by the first device to the second device at the same time, and the frequency of the fault detection message sent by the second device to the first device. In this way, the fault detection message sent by the first device The frequency of the detection message is reduced, and the frequency of sending the fault detection message by the second device is also reduced. Therefore, the data transmission is reduced and the network load is reduced.

Since the user equipment corresponding to the second device will not send service data to the first device when it is determined that no service connection has been established between the first device and all user equipment corresponding to the second device, there is no need to send faults at a high frequency at this time Detecting messages, at this time, when it is determined that the frequency of sending fault detection messages of the first device is not less than the first threshold, adjust the frequency of sending fault detection messages of the first device, so that the adjusted first device sends fault detection messages is less than the first threshold, and/or when it is determined that the frequency at which the second device sends fault detection messages is not less than the second threshold, adjust the frequency at which the second device sends fault detection messages so that the adjusted second device sends The frequency of the fault detection message is less than the second threshold, that is, the frequency of sending the fault detection message is reduced, thereby reducing network load, reducing network overhead, and saving network resources.

Optionally, when it is determined that at least one user equipment corresponding to the second device establishes a service connection with the first device, the number of service data sent by the second device received within a preset time period is determined; wherein, the preset The duration can be determined according to the specific situation, such as setting it to 1 second or 10 seconds based on experience;

When it is determined that the number of business data is zero, determine the frequency of the first device to send the fault detection message, and when it is determined that the frequency of the first device to send the fault detection message is less than the first threshold, adjust the first device to send the fault detection message frequency, so that the adjusted frequency of the first device sending the fault detection message is not less than the first threshold; and/or

When it is determined that the amount of business data is zero, determine the frequency of the second device sending the fault detection message, and when it is determined that the frequency of the second device sending the fault detection message is less than the second threshold, adjust the second device to send the fault detection message frequency, so that the adjusted frequency of the second device sending the fault detection message is no less than the second threshold.

Since at least one user equipment corresponding to the second device is determined to establish a service connection with the first device, the user equipment must transmit service data through the second device and the first device, if the received The number of service data sent by the second device is zero, which means that the second device has not transmitted the service data corresponding to the user equipment to the first device within the preset time period. At this time, it is determined that the second device may be faulty. Therefore, the The frequency of fault detection messages is increased. In this way, when a device or link fails, the fault detection rate is increased, thereby reducing the interruption time of data transmission when the device or link fails.

Furthermore, when the second device fails, the transmission of service data on the second device is interrupted. At this time, when the service data transmitted on the second device is found to be interrupted on a certain interface, the frequency of sending fault detection messages is immediately increased. The first The device sends fault detection packets through this interface. Since most of the time a single device fails, increasing the frequency of sending fault detection packets by individual devices will not bring a large load to the network, and the fault detection speed will also be improved.

Optionally, when it is determined that at least one user equipment connected to the second device establishes a service connection with the first device, the amount of service data sent by the second device received within a preset time period is determined;

When it is determined that the quantity of business data is not zero, and when the first device sends a fault detection message to the second device, adjust the frequency of the first device to send the fault detection message, so that the adjusted first device stops sending the fault detection message to the second device. The second device sends a fault detection message; and/or

When it is determined that the quantity of business data is not zero, and when the second device sends a fault detection message to the first device, adjust the frequency of the second device to send the fault detection message, so that the adjusted second device stops sending the fault detection message to the first device. The first device sends a fault detection packet.

Since at least one user equipment corresponding to the second device is determined to establish a service connection with the first device, the user equipment must transmit service data through the second device and the first device, if the received If the number of business data sent by the second device is not zero, it means that the links and devices between the first device and the second device are normal. At this time, you can stop sending fault detection messages to reduce the network load and reduce the network load. overhead, saving network resources.

Another optional implementation manner is that when it is determined that at least one user equipment connected to the second device establishes a service connection with the first device, it is determined that the service data sent by the second device is received within a preset time period. quantity;

When it is determined that the amount of business data is not zero, determine the frequency at which the first device sends a fault detection message; when it is determined that the frequency at which the first device sends a fault detection message is not less than the first threshold, adjust the first device to send a fault detection The frequency of the message, so that the adjusted frequency of the first device sending the fault detection message is less than the first threshold; and/or

When it is determined that the amount of business data is not zero, determine the frequency at which the second device sends the fault detection message; when it is determined that the frequency at which the second device sends the fault detection message is not less than the second threshold, adjust the second device to send the fault detection message The frequency of the message, so that the adjusted frequency of the second device sending the fault detection message is less than the second threshold.

Since at least one user equipment corresponding to the second device is determined to establish a service connection with the first device, the user equipment must transmit service data through the second device and the first device, if the received If the number of business data sent by the second device is not zero, it means that the link and equipment between the first device and the second device are normal. At this time, the frequency of sending fault detection messages can be reduced. On the other hand, it reduces network load, reduces network overhead, and saves network resources.

In the above embodiment, optionally, when it is determined that the frequency at which the first device sends the fault detection message is not less than the first threshold, the frequency at which the first device sends the fault detection message is adjusted according to the amount of service data; wherein, the service data The smaller the number, the greater the frequency of the first device to send fault detection packets after adjustment; when it is determined that the frequency of the second device to send fault detection packets is not less than the second threshold, adjust the second device according to the amount of business data. The frequency of the detection message; wherein, the smaller the amount of service data is, the higher the frequency of the adjusted second device is to send the fault detection message.

In this way, the sending frequency of fault detection messages can be flexibly determined according to the sending volume of service data corresponding to the user equipment, which can more effectively realize the detection of links and devices, and more effectively reduce network load, reduce network overhead, and save network resources.

In order to more clearly introduce the flow of the above method, FIG. 3a exemplarily shows a schematic flow diagram of another fault detection method provided by an embodiment of the present invention, as shown in FIG. 3a, including:

Step 3101, determine whether service connections are established between all user equipment corresponding to the second device and the first device, if not, perform step 3102, and if yes, perform step 3103;

Step 3102: Determine the frequency at which the first device sends the fault detection message, and when it is determined that the frequency at which the first device sends the fault detection message is not less than the first threshold, adjust the frequency at which the first device sends the fault detection message so that after adjustment The frequency at which the first device sends the fault detection message is less than the first threshold; and/or

Determine the frequency at which the second device sends the fault detection message; when determining that the frequency at which the second device sends the fault detection message is not less than the second threshold, adjust the frequency at which the second device sends the fault detection message so that the adjusted second The frequency at which the device sends fault detection packets is less than the second threshold.

Step 3103, determine the number of business data sent by the second device received within the preset time length, and judge whether the number of business data is zero; if yes, execute step 3104; if not, execute step 3105 or step 3106 ;

Step 3104: Determine the frequency at which the first device sends the fault detection message, and when it is determined that the frequency at which the first device sends the fault detection message is less than the first threshold, adjust the frequency at which the first device sends the fault detection message so that the adjusted The frequency at which the first device sends the fault detection message is not less than the first threshold; and/or

Determine the frequency at which the second device sends the fault detection message, and adjust the frequency at which the second device sends the fault detection message when it is determined that the frequency at which the second device sends the fault detection message is less than the second threshold, so that the adjusted second device The frequency of sending the fault detection message is not less than the second threshold.

Step 3105, determining that when sending the fault detection message to the second device, adjust the frequency of sending the fault detection message by the first device, so that the adjusted first device stops sending the fault detection message to the second device; and/or

It is determined that when the second device sends the fault detection message to the first device, the frequency of sending the fault detection message by the second device is adjusted, so that the adjusted second device stops sending the fault detection message to the first device.

Step 3106, determine the frequency of the first device to send the fault detection message; when it is determined that the frequency of the first device to send the fault detection message is not less than the first threshold, adjust the frequency of the first device to send the fault detection message, so that after adjustment The frequency at which the first device sends the fault detection message is less than the first threshold; and/or

Determine the frequency at which the second device sends the fault detection message; when determining that the frequency at which the second device sends the fault detection message is not less than the second threshold, adjust the frequency at which the second device sends the fault detection message so that the adjusted second The frequency at which the device sends fault detection packets is less than the second threshold.

In order to describe the above method more clearly, Fig. 3b exemplarily illustrates a schematic diagram of the relationship between the sending frequency of the fault detection message and the quantity of service data provided by the embodiment of the present invention. As shown in Figure 3b, the thick solid line represents the quantity of service data, and the dotted line represents the frequency of sending fault detection messages. When the service connection is not established, the amount of service data between the first device and the second device is zero, at this time, send the fault detection message with a relatively small frequency, for example, send the fault detection message with a frequency less than the first threshold . When the business connection has been established, the amount of business data is inversely proportional to the frequency of sending fault detection messages, that is to say, the larger the amount of business data, the lower the frequency of sending fault detection messages. When the number is large, the sending of fault detection packets can be stopped. When the service connection has been established but the amount of service data is zero, increase the frequency of sending fault detection messages so as to quickly locate the faulty equipment or transmission line.

It can be seen from the above that in the embodiment of the present invention, it is determined that no service connection has been established between all user equipment corresponding to the first device and the second device; wherein the service data of the user equipment corresponding to the second device passes through the second device and the second device A device transmits; determine the frequency at which the first device sends the fault detection message, and adjust the frequency at which the first device sends the fault detection message when it is determined that the frequency at which the first device sends the fault detection message is not less than the first threshold, so that The adjusted frequency of the first device sending the fault detection message is less than the first threshold; and/or determining the frequency of the second device sending the fault detection message; after determining that the frequency of the second device sending the fault detection message is not less than the second threshold , adjust the frequency at which the second device sends the fault detection packet, so that the adjusted frequency at which the second device sends the fault detection packet is less than the second threshold. Since the user equipment corresponding to the second device will not send service data to the first device when it is determined that no service connection has been established between the first device and all user equipment corresponding to the second device, there is no need to send faults at a high frequency at this time Detecting messages, at this time, when it is determined that the frequency of sending fault detection messages of the first device is not less than the first threshold, adjust the frequency of sending fault detection messages of the first device, so that the adjusted first device sends fault detection messages is less than the first threshold, and/or when it is determined that the frequency at which the second device sends fault detection messages is not less than the second threshold, adjust the frequency at which the second device sends fault detection messages so that the adjusted second device sends The frequency of the fault detection message is less than the second threshold, that is, the frequency of sending the fault detection message is reduced, thereby reducing network load, reducing network overhead, and saving network resources.
