Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic diagram of an implementation environment according to an embodiment of the present application. In fig. 1, an autonomous server a is deployed in an autonomous domain 1, and an autonomous server B and an autonomous server C are deployed in an autonomous domain 2. The autonomous server A is connected with the cascade equipment 1 through the sub-control server 1, is connected with the terminal through the sub-control server 2, and is connected with the cascade equipment 3 through the sub-control server 3, and the sub-control server and the cascade equipment are used for data forwarding. The boundary routing device group 1 is connected to the cascade device 1 through a port No. 1 on one hand, and is connected to the autonomous server B through a port No. 0 on the other hand, and the boundary routing device group 1 includes a boundary routing device 1 (currently in an active mode) and a boundary routing device 2 (currently in a backup mode). The boundary routing device group 2 is connected to the cascade device 3 through the port 1 on one hand, and is connected to the autonomous server C through the port 0 on the other hand, and the boundary routing device group 2 includes a boundary routing device 3 (currently in an active mode) and a boundary routing device 4 (currently in a backup mode).

The application provides a service recovery method, which is applied to the border routing device in fig. 1. Fig. 2 is a flowchart illustrating a service restoration method according to an embodiment of the present application. Referring to fig. 2, the service restoration method of the present application may include the steps of:

step S21: and when the self working mode is detected to be switched to the active mode, sending a boundary route switching notice to the autonomous server in the autonomous domain.

In this embodiment, the operation modes of the border routing device include: an active mode and a backup mode. In a border routing device group, a border routing device is supported in an active mode at the same time. Taking the border routing device group 1 shown in fig. 1 as an example, when the border routing device 1 is in the active mode, the border routing device 2 should be in the backup mode, and when the border routing device 2 is in the backup mode, the border routing device 2 should be in the active mode.

In this embodiment, each border routing device has two ports, and the border routing device is connected to the upper autonomous domain through one port and connected to the lower autonomous domain through the other port. Taking the boundary routing device 1 shown in fig. 1 as an example, the boundary routing device 1 is connected to the cascade device 1 of the autonomous domain 1 through the port No. 1, and is connected to the autonomous server B of the autonomous domain 2 through the port No. 0.

In this embodiment, each border routing device (including the border routing device in the active mode and the border routing device in the backup mode) is connected to the cascade device of the autonomous domain at the previous stage on the one hand, and is connected to the autonomous server of the autonomous domain at the next stage on the other hand. Taking the boundary routing device a shown in fig. 1 as an example, the boundary routing device 1 is connected to the cascade device 1 on one hand and the autonomous server B on the other hand, and meanwhile, the boundary routing device 2 is connected to the cascade device 1 on one hand and the autonomous server B on the other hand.

In this embodiment, the border routing device belongs to both autonomous domains. Taking the border routing device 1 shown in fig. 1 as an example, the border routing device 1 belongs to both the autonomous domain 1 and the autonomous domain 2, that is: the autonomous domain to which the border routing device belongs includes: autonomous domain 1 and autonomous domain 2.

During specific implementation, the border routing device detects that its own working mode is switched to an active mode, which indicates that a border routing device switching event occurs, and at this time, the border routing device switched to the active mode sends a border routing switching notification to all autonomous servers in its own autonomous domain. Taking the boundary routing device 1 shown in fig. 1 as an example, after the boundary routing device 1 switches to the active mode, a boundary routing switching notification is simultaneously sent to the autonomous server a and the autonomous server B, so that the autonomous server a and the autonomous server B perform a recovery operation on a service before switching.

Step S22: and receiving a multicast link control command sent by the autonomous server.

In this embodiment, the multicast link control command is used to restore the multicast link. The multicast link control command sent by the autonomous server a is used to restore the multicast link involved between the autonomous server a and the border routing device that was in active mode before the handover occurred. The multicast link control command sent by the autonomous server B is used to restore the multicast link involved between the autonomous server B and the border routing device in active mode before the handover occurs. A multicast link may be understood as a path for transmitting data.

Illustratively, taking the boundary routing device group 1 shown in fig. 1 as an example, assuming that the boundary routing device 2 is in an active mode before a handover event occurs and the boundary routing device 1 is in an active mode after the handover event occurs, the multicast link control command sent by the autonomous server a is used to recover the multicast link involved between the autonomous server a and the boundary routing device 2, and the multicast link control command sent by the autonomous server B is used to recover the multicast link involved between the autonomous server B and the boundary routing device 2.

Illustratively, the multicast link may be: other devices 1-autonomous server a-sub control server 1-cascade device 1-border routing device 2-autonomous server B-other devices 2. Among them, the other device 1 may be a device in the upper level autonomous domain to which the autonomous server a is connected, and the other device 2 may be another device to which the autonomous server B is connected. There may be other types of multicast links, and the embodiment does not limit the specific form of the multicast link.

Step S23: and recovering the multicast link between the multicast link control command and the autonomous server according to the multicast link control command.

In this embodiment, the multicast link control command includes multicast link information before switching, and after receiving the multicast link control command, the boundary routing device after switching updates its own multicast link according to the multicast link information in the multicast link control command. For example, after the border routing device 1 in fig. 1 switches to the active mode, one piece of multicast link information in the multicast link control command sent by the autonomous server a is received as: other equipment 1-the autonomous server A-the sub-control server 1-the cascade equipment 1-the boundary route equipment 2-the autonomous server B-other equipment 2, then the boundary route equipment 1 stores the multicast link information at first, and then the boundary route equipment 2 in the multicast link information is replaced by the boundary route equipment 1 to replace the original boundary route equipment 1 to continue to execute the subsequent data forwarding work.

Step S24: and receiving a data source state control command sent by the autonomous server.

In the present embodiment, the data source status control command is used to control the transmission of data. For example, when the data source status of the target data is the sending status, the boundary routing device performs the sending operation on the target data, and when the data source status of the target data is the non-sending status, the boundary routing device does not perform the sending operation on the target data. The performance of the video networking for processing the service is limited, and under a high concurrency request, the video networking cannot simultaneously respond to all service requests to transmit service data, so that each service request needs to be responded according to a preset processing rule (for example, processing according to time sequence, processing according to priority, and the like), and therefore, in actual execution, the autonomous server needs to send a data source state control command to the boundary routing equipment, so that the boundary routing equipment forwards the data according to the data source state of each data, and smooth operation of the video networking service is ensured.

Step S25: and performing data source state configuration on the recovered multicast link according to the data source state control command.

In this embodiment, the data source state control command includes data source states of multiple multicast links, and the border routing device configures a corresponding multicast link according to the data source state of each multicast link.

One multicast link corresponds to one path of data. When the data source state of a multicast link is 'send', the boundary routing equipment executes sending operation when receiving the data sent by the multicast link. When the data source state of a multicast link is 'no transmission', the boundary routing equipment does not execute the transmission operation when receiving the data transmitted by the multicast link.

Illustratively, when a terminal 1 and a terminal 2 perform video call in the video network, audio and video data 1 sent to the terminal 2by the terminal 1 corresponds to a multicast link 1, and audio and video data 2 sent to the terminal 1 by the terminal 2 corresponds to a multicast link 2. And if the data source state corresponding to the multicast link 1 is 'sending' at a certain moment, the boundary routing equipment executes sending operation when receiving the audio and video data 1. If the data source state corresponding to the multicast link 2 is "not to send" at a certain time, the boundary routing device does not execute sending operation when receiving the audio/video data 2.

Step S26: and when the multicast link is successfully recovered and the data source state is successfully configured, determining that the multicast service between the self and the autonomous server is successfully recovered.

In this embodiment, after the border routing device completes the recovery of the multicast link and the configuration of the data source state of the multicast link, the border routing device and the autonomous server may continue to execute the original multicast service before switching, for example, a multicast service for data transmission based on the multicast link, such as a live broadcast, a conference, a video telephone, and the like.

The above steps S21 to S26 will be described in detail as an embodiment.

Referring to fig. 1, after the boundary routing device 1 in the boundary routing device group 1 switches to the active mode, the boundary routing device 1 transmits a boundary route switching notification to the autonomous server a and the autonomous server B, respectively. After receiving the multicast link control command and the data source state control command sent by the autonomous server a, the boundary routing device 1 recovers the multicast link with the autonomous server a according to the multicast link control command, and performs data source state configuration on the recovered multicast link according to the data source state control command. After receiving the multicast link control command and the data source state control command sent by the autonomous server B, the boundary routing device 1 recovers the multicast link with the autonomous server B according to the multicast link control command, and performs data source state configuration on the recovered multicast link according to the data source state control command. In this way, the multicast service interrupted by the handover event between the border router 1 and the autonomous server a and B can be recovered. It is understood that the operation principle of the border routing device 1 for the multicast link control command and the data source status control command sent by the autonomous server a is the same as that of the multicast link control command and the data source status control command sent by the autonomous server B.

With reference to the foregoing embodiment, in an implementation manner, the multicast link control command includes: routing data and multicast steering table data. On the basis, the application also provides a method for recovering the multicast link. Specifically, the step S23 may include:

In this embodiment, the routing data is composed of multicast addresses of a plurality of devices. For example, the routing data { a1, a2, A3 …, a7} is composed of respective multicast addresses of 7 devices, a1-a7, and the multicast address of each device can be set using its device number. The multicast direction table data indicates the direction of copying of multicast data between ports in the multicast data itself, after each device receives the multicast data. Illustratively, when a3 is the multicast address of the boundary router, its own internal ports include port No. 1 and port No. 0, and the multicast direction table data for the boundary router indicates that after the boundary router receives the multicast data, the direction of copying the multicast data between its own internal ports is to copy the multicast data from port No. 1 to port No. 0 or from port No. 0 to port No. 1.

In this embodiment, the multicast link may be recovered according to the routing data and the multicast steering table data. In specific implementation, the border routing device first stores routing data, and then sets a data copy direction of each multicast address between its corresponding device ports according to the multicast guide table data. Illustratively, the border routing device stores routing data { a1, a2, A3, a4, A5, A6, a7}, and then the border routing device sets the data copy direction { (port 1) a1 (port 2), (port 3) a2 (port 4), (port 5) A3 (port 6), (port 7) a4 (port 8), (port 9) A5 (port 10), (port 11) A6 (port 12), (port 13) a7 (port 14) } inside each device, so that multicast links a1-a2-A3-a4-A5-A6-a7 can be formed. Here, the (port X) AY (port Z) indicates that the device AY receives multicast data through the port X and transmits the multicast data through the port Z.

By the method for recovering the multicast link according to the embodiment, the recovery of the multicast link before switching can be realized after the boundary routing device is switched, so that the smooth recovery of the multicast service before switching is ensured.

With reference to the foregoing embodiment, in an implementation manner, the data source status control command includes a data source status of each multicast link, where the data source status includes a first status and a second status, the first status is used to indicate that multicast data of a corresponding multicast link is transmitted, and the second status is used to indicate that multicast data of a corresponding multicast link is not transmitted. On the basis, the application also provides a method for configuring the state of the data source of the multicast link. Specifically, the step S25 includes:

For example, the first state may be represented by "0" and the second state may be represented by "1", and of course, the first state and the second state may also be represented by other marks, which is not specifically limited in this embodiment. When the recovered multicast link is { (port 1) a1 (port 2), (port 3) a2 (port 4), (port 5) A3 (port 6), (port 7) a4 (port 8), (port 9) a5 (port 10), (port 11) A6 (port 12), or (port 13) a7 (port 14) }, the multicast link obtained by updating the data source state of the multicast link may be { (port 1) a1 (port 2), (port 3) a2 (port 4), (port 5) A3 (port 6), (port 7) a4 (port 8), (port 9) a5 (port 10), (port 11) A6 (port 12), or port 13) a7 (port 14); state "0", which indicates that the border routing device executes the sending operation when receiving the multicast data sent by the multicast link.

By the method for configuring the data source state of the multicast link according to the embodiment, the data source state of the recovered multicast link can be configured after the boundary routing device is switched, so that the smooth recovery of the multicast service before switching is ensured.

With reference to the foregoing embodiment, in an implementation manner, the service recovery method of the present application may further include:

In this embodiment, the boundary router in the active mode in one boundary router group establishes heartbeat connections with all the boundary routers in the backup mode in the boundary router group. Through heartbeat connection, the boundary routing equipment in the active mode and the boundary routing equipment in the backup mode can acquire the state of the other side in real time, when the boundary routing equipment in the backup mode detects that the heartbeat connection between the boundary routing equipment in the active mode is over time, the boundary routing equipment in the active mode is determined to have a fault, and the working mode of the boundary routing equipment in the active mode is switched to the active mode immediately so as to replace the original boundary routing equipment in the active mode to continue the video networking service.

Illustratively, in fig. 1, a heartbeat connection is established between the border routing device 1 and the border routing device 2, when the border routing device 2 in the backup state does not receive the heartbeat packet sent by the border routing device 1 in the active state within the preset time period, it is determined that the border routing device 1 fails, and then the working mode of the border routing device 1 is switched to the active state to take over the border routing device 1 to continue to execute the multicast service.

In this embodiment, the border routing device in the backup mode determines whether the border routing device in the active mode fails according to the heartbeat connection with the border routing device in the active mode, and switches its working mode to the active mode when the border routing device in the backup mode fails, so as to take over the original border routing device in the active mode to continue the video networking service, thereby ensuring that the video networking normally performs multicast data transmission across the autonomous service.

In combination with the above embodiment, in an implementation manner, the step S21 may include:

In this embodiment, the border routing device may send the border route switching notification in any one of the following two ways: firstly, directly sending a notice for determining the occurrence of a boundary routing equipment switching event to an autonomous server in the autonomous domain; secondly, the autonomous server in the autonomous domain sends the current working mode of the autonomous server, so that the autonomous server can determine that the boundary routing equipment switching event occurs according to the change of the working mode of the boundary routing equipment. Of course, the border routing device may also send the border routing switching notification to the autonomous server in other manners, which is not limited in this embodiment.

Illustratively, taking the boundary routing device group 1 in fig. 1 as an example, when the boundary routing device 1 sends its current working mode, i.e., active mode, to the autonomous server a, the autonomous server a knows that the boundary routing device 1 is switched from the backup mode to the active mode, and determines that a boundary routing device switching event occurs in the boundary routing device group 1.

With reference to the foregoing embodiment, in an implementation manner, the boundary routing device is provided with a first port and a second port, and the boundary routing device is connected to an autonomous server in a first autonomous domain through the first port and is connected to an autonomous server in a second autonomous domain through the second port. On this basis, the step S21 may include:

Referring to fig. 1, the first port and the second port may be understood as a No. 1 port and a No. 0 port. The boundary routing device is connected with the autonomous server in the first autonomous domain through the first port, which can be understood as that the boundary routing device 1 is connected with the autonomous server a through the port No. 1. The boundary routing device is connected to the autonomous server in the second autonomous domain through the second port, which can be understood as that the boundary routing device 1 is connected to the autonomous server B through the port No. 0. For the description of the first port and the second port, please refer to the foregoing description, and the description of the embodiment is omitted here.

The present application also provides another service recovery method, which is applied to the autonomous server shown in fig. 1. Fig. 3 is a flowchart illustrating another service recovery method according to an embodiment of the present application. Referring to fig. 3, the service restoration method of the present application may include the steps of:

step S31: and when receiving a boundary route switching notification sent by the boundary route equipment, generating a multicast link control command according to the multicast link data passing through the boundary route equipment.

Taking fig. 1 as an example, when the autonomous server a receives a boundary route switching notification (which is switched to the boundary routing device 1 by the boundary routing device 2) sent by the boundary routing device 1, it queries information of all multicast links passing through the boundary routing device 2 before switching, and generates a multicast link control command according to the queried information of the multicast links.

Step S32: and sending the multicast link control command to the boundary routing equipment so that the boundary routing equipment recovers the multicast link between the boundary routing equipment and the autonomous server according to the multicast link control command.

Following the example in step S31 described above, after the autonomous server a generates the multicast link control command, the multicast link control command is sent to the border routing device 1, so that the border routing device 1 restores the multicast link with the autonomous server a according to the multicast link control command.

Step S33: and sending a data source state control command to the boundary routing equipment so that the boundary routing equipment performs data source state configuration on the recovered multicast link according to the data source state control command.

Following the example in the above-mentioned step S31-step S32, the autonomous server a continues to transmit the data source state control command to the border routing device 1, so that the border routing device 1 performs data source state configuration on the recovered multicast link according to the data source state control command.

Step S34: and after receiving the message that the multicast link returned by the boundary routing equipment is successfully recovered and the data source state configuration is successful, determining that the multicast service between the boundary routing equipment and the boundary routing equipment is successfully recovered.

Following the example from the above step S31 to step S33, after the autonomous server a receives the message that the multicast link recovery is successful and the data source status configuration is successful, which is returned by the border routing device 1, it is determined that the multicast service recovery between the autonomous server a and the border routing device 1 is successful.

By the service recovery method of the embodiment, when the boundary router fails, the backup boundary router does not need to be manually reset to recover the original multicast link, the multicast link can be automatically recovered, the recovery efficiency of the multicast service is improved, and normal multicast data transmission of the video networking across autonomous services is ensured.

With reference to the foregoing embodiment, in an implementation manner, after the step S33, the service recovery method of the present application may further include:

In this embodiment, after the original multicast service is successfully recovered, the border routing device may forward the multicast data according to the recovered multicast link.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.

2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is proposed, and following a protocol of the video network, when detecting that a working mode of a boundary routing device is switched to an active mode, the boundary routing device first sends a boundary routing switching notification to an autonomous server in a subordinate autonomous domain. After receiving the multicast link control command sent by the autonomous server, the multicast link between the autonomous server and the multicast link is recovered according to the multicast link control command. And after receiving the data source state control command sent by the autonomous server, performing data source state configuration on the recovered multicast link according to the data source state control command. And when the multicast link is successfully recovered and the data source state is successfully configured, determining that the multicast service between the self and the autonomous server is successfully recovered.
