Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of network, and particularly relates to a method for detecting 802.1CB link, 802.1CB link, electronic equipment and storage medium. BACKGROUND

[0002] IEEE 802.1CB is a sub-protocol in the TSN (Time-Sensitive Network) protocol family, which defines a frame replication and elimination mechanism (Frame Replication and Elimination for Reliability) to improve network reliability through redundant transmission.

[0003] IEEE 802.1CB can implement the following functions: frame replication: redundant messages of a key data stream (such as industrial control instructions, sensor data on a vehicle) are sent through multiple independent paths; frame elimination: the receiving end only retains the first valid message that arrives and discards subsequent redundant frames.

[0004] And generally, IEEE 802.1CB adopts a redundant path design to facilitate the transmission of data streams through disjoint paths in the network, so that even if a certain path fails due to link failure, data can still be guaranteed to be reachable through other paths.

[0005] However, due to the relatively complex configuration of 802.1CB, the roles of 802.1CB at different nodes are different, and the configuration is relatively complex. If the expected result is different from the actual result, the configuration personnel will also have a relatively difficult situation to troubleshoot. In addition, during the operation of the protocol, if there is a link problem, it is also difficult to diagnose the problem.

[0006] Therefore, there is a problem in the related art that it is difficult to detect the correctness of the 802.1CB link. SUMMARY

[0054] According to an aspect of an embodiment of the present application, a method for detecting 802.1CB links is provided. Optionally, in the present embodiment, the above-mentioned method for detecting 802.1CB links can be applied in the hardware environment composed of the terminal 1402 and the server 1404 as shown in Figure 1 As shown in Figure 1 The server 1404 is connected with the terminal 1402 through the network, and can be used to provide services (such as game services, application services, etc.) for the terminal or the client installed on the terminal, and a database can be set on the server or independently of the server, to provide data storage services for the server 1404.

[0055] The network can include, but is not limited to, at least one of the following: a wired network, a wireless network. The wired network can include, but is not limited to, at least one of the following: a wide area network, a metropolitan area network, a local area network. The wireless network can include, but is not limited to, at least one of the following: WIFI (Wireless Fidelity), Bluetooth. The terminal can be, but is not limited to, a PC, a mobile phone, a tablet computer, etc.

[0056] The method for detecting the 802.1CB link in the embodiment of the application can be executed by a server, or by a terminal, or by both the server and the terminal. The terminal can execute the method for detecting the 802.1CB link in the embodiment of the application by a client installed thereon.

[0057] Taking the method for detecting the 802.1CB link in the embodiment as an example, Figure 2 A method for detecting an 802.1CB link provided in the embodiment of the application is applied to a source node and includes the following steps.

[0058] In step S202, each original packet is copied, and a redundancy tag is added to the copied packet to obtain a target packet corresponding to each original packet.

[0059] The method for detecting the 802.1CB link in the embodiment of the application can be applied to a scenario in which it is necessary to detect whether the source node in the 802.1CB link is abnormal.

[0060] In the embodiment, the source node is a device at the copy starting point.

[0061] The source node can copy each original packet collected to obtain a copied packet corresponding to each original packet, and then add a redundancy tag (R-TAG) to each copied packet to obtain a target packet corresponding to each original packet.

[0062] In step S204, all original packets are sampled at a target sampling rate to obtain original sampling packets.

[0063] That is, after all original packets are obtained, the original packets can be sampled at a preset target sampling rate to obtain original sampling packets.

[0064] The target sampling rate in the embodiment is configured according to the ability of the CPU, and all the traffic matched by the ACL (Access Control List) is processed by the CPU, which causes the CPU to be unable to process all the traffic, i.e., unable to process all the original packets. Therefore, a fixed proportion sampling needs to be configured according to the ability of the CPU. In the embodiment, the target sampling rate can be 1000 packets collected per one. That is, one original sampling packet is sampled from 1000 original packets, i.e., sampling once every 999 original packets.

[0065] Further, the collected original sampling packet is sent to the CPU for comparison with the packet sampled subsequently.

[0066] In step S206, all the target packets are sampled at the target sampling rate to obtain the first target sampling packet.

[0067] That is, after all the target packets are obtained, the target packets can be sampled at the preset target sampling rate to obtain the first target sampling packet.

[0068] The target sampling rate in the embodiment is configured according to the ability of the CPU, and all the traffic matched by the ACL (Access Control List) is processed by the CPU, which causes the CPU to be unable to process all the traffic, i.e., unable to process all the target packets. Therefore, a fixed proportion sampling needs to be configured according to the ability of the CPU. In the embodiment, the target sampling rate can be 1000 packets collected per one. That is, one first target sampling packet is sampled from 1000 target packets, i.e., sampling once every 999 target packets.

[0069] Further, after the target packet is obtained, the target packet is sent from the specified port according to the configuration, and at the same time, the first target sampling packet sampled is sent to the CPU for comparison with other sampled packets.

[0070] In step S208, in the case that the sampling point difference between the original sampling packets sampled at adjacent two times is consistent with the redundancy label difference between the first target sampling packets sampled at adjacent two times, it is determined that the packet replication of the source node is correct.

[0071] After the original sampling packet and the target sampling packet are sampled, the serial number of the sampling point of the original packet and the redundancy tag R-TAG of the target sampling packet can be compared by the CPU, and the difference value is required to be equal, otherwise a copy error alarm will be caused. For example, when the original sampling packet is sampled, the sampling point can be recorded at the end of the original sampling packet. For example, the sampling rate is 1000, that is, 1000 samples, if the first sampling falls on the 100th packet, the recorded sampling point is 100, the next sampling is 1100, and so on. That is, when the target sampling rate is 1000, the difference value of the sampling points of the original sampling packets sampled by adjacent two times is 1000. The first target sampling packet obtained by copying is added with R-TAG at the export, and the R-TAG of the first target sampling packet sampled first is 101, and the R-TAG of the next first target sampling packet is 1101. That is, when the target sampling rate is 1000, the difference value of the redundancy tags of the first target sampling packets sampled by adjacent two times is 1000. Further, since the target sampling rate is consistent, when the sampling point difference value and the redundancy tag difference value are consistent, it is determined that the packet copying of the source node is correct.

[0072] Alternatively, the original sampling packet and the first target sampling packet sampled at adjacent time points can also be taken as a group, and the difference value of each group of sampling packets is calculated. For example, based on the foregoing example, when the sampling point of the original sampling packet sampled first is 100, and the R-TAG of the first target sampling packet is 101, the difference value of the sampling packets in this group is 1, and when the sampling point of the original sampling packet sampled second is 1100, and the R-TAG of the second first target sampling packet is 1101, the difference value of the sampling packets in this group is also 1, so the packet copying of the source node can also be determined to be correct.

[0073] In the embodiment, each original packet is copied, and a redundancy tag is added in the copied packet to obtain a target packet corresponding to each original packet; all original packets are sampled at a target sampling rate to obtain original sampling packets; all target packets are sampled at the target sampling rate to obtain first target sampling packets; and in a case where the difference value of the sampling points between the original sampling packets sampled by adjacent two times is consistent with the difference value of the redundancy tags between the target sampling packets sampled by adjacent two times, it is determined that the packet copying of the source node is correct. Since whether the difference value of the sampling points between the original sampling packets sampled by adjacent two times is consistent with the difference value of the redundancy tags between the target sampling packets sampled by adjacent two times can be used to determine whether the packet copying of the source node is correct, the technical effect that the correctness of the 802.1CB link can be quickly detected is achieved, and the problem that the correctness of the 802.1CB link is difficult to detect in the related art is solved.

[0074] As an optional implementation, the method further comprises the following steps of:

[0075] In a case where the difference between the sampling points of the original sampled packets of the adjacent two times is inconsistent with the difference between the redundant labels of the first target sampled packets of the adjacent two times, it is determined that the packet replication of the source node is abnormal. That is, in a case where the difference between the sampling points of the original sampled packets of the adjacent two times is inconsistent with the difference between the redundant labels of the first target sampled packets of the adjacent two times, it is indicated that the replication of the original packet appears repeated replication (i.e., the number of target packets is more than that of original packets) or missing replication (i.e., the number of target packets is less than that of original packets), which further causes the above-mentioned situation to occur. For example, taking the target sampling rate of 1000 as an example, if repeated replication occurs, since the sampling rate is unchanged, and the target packets corresponding to one or more original packets are more than one, the difference between the redundant labels of the first target sampled packets of the adjacent two times will be less than 1000; if missing replication occurs, since the sampling rate is unchanged, and the target packets corresponding to one or more original packets are missing, the difference between the redundant labels of the first target sampled packets of the adjacent two times will be greater than 1000; thus, in a case where the difference between the sampling points of the original sampled packets of the adjacent two times is inconsistent with the difference between the redundant labels of the first target sampled packets of the adjacent two times, it is determined that the packet replication of the source node is abnormal.

[0076] In a case where the at least one first target sampled packet does not have a redundant label, it is determined that the packet replication of the source node is abnormal. That is, the CPU determines that the packet replication of the source node is abnormal in a case where the at least one first target sampled packet does not have a redundant label, i.e., the at least one first target sampled packet does not carry an R-TAG.

[0077] As shown in Figure 3 According to another aspect of the embodiments of the present application, a method for detecting an 802.1CB link is also provided, applied to a replication relay node, comprising the following steps:

[0078] In step S302, each packet obtained is replicated to obtain a first replicated packet corresponding to each packet.

[0079] That is, after the replication relay node obtains a packet from a source node or other replication relay nodes or the like, each packet obtained can be replicated to obtain a first replicated packet corresponding to each packet.

[0080] In step S304, all packets are sampled at a target sampling rate to obtain second target sampled packets.

[0081] That is, after obtaining all the packets, the above all packets can be sampled according to a preset target sampling rate to obtain second target sampling packets.

[0082] In the embodiment, the target sampling rate is configured according to the capability of the CPU, and all the traffic matched by the ACL (Access Control List) is processed by the CPU, which causes the CPU to be unable to process all the traffic, that is, unable to process all the packets. Therefore, a fixed proportion sampling needs to be configured according to the capability of the CPU. In the embodiment, the target sampling rate can be one packet in 1000 packets. That is, one second target sampling packet is sampled in 1000 packets, that is, sampling once every 999 original packets.

[0083] Further, the obtained second target sampling packets are sent to the CPU for comparison with other sampled packets.

[0084] In step S306, the first copy sampling packets are obtained by sampling each group of first copy packets according to the target sampling rate, wherein each group of first copy packets includes a first copy packet corresponding to each packet.

[0085] The replication relay node can replicate each packet to obtain at least one group of copy packets corresponding to all the packets, and sample each group of first copy packets according to the target sampling rate to obtain first copy sampling packets. That is, after obtaining at least one group of copy packets, each group of copy packets can be sampled according to a preset target sampling rate to obtain first copy sampling packets.

[0086] In the embodiment, the target sampling rate is configured according to the capability of the CPU, and all the traffic matched by the ACL (Access Control List) is processed by the CPU, which causes the CPU to be unable to process all the traffic, that is, unable to process all the first copy packets. Therefore, a fixed proportion sampling needs to be configured according to the capability of the CPU. In the embodiment, the target sampling rate can be one packet in 1000 packets. That is, one first copy sampling packet is sampled in 1000 first copy packets, that is, sampling once every 999 first copy packets.

[0087] Further, after obtaining the first copy packets, the first copy packets are sent from the specified port according to the configuration, and at the same time, the first copy sampling packets sampled are sent to the CPU for comparison with other sampled packets.

[0088] Step S308, if the difference of the redundancy labels between the second target sampling packets of the adjacent two times of sampling is consistent with the difference of the redundancy labels between the first copy sampling packets of the adjacent two times of sampling, it is determined that the packet copying of the copy relay node is correct.

[0089] After the second target sampling packet and the first copy sampling packet are sampled, the redundancy label of the second target sampling packet can be compared with the redundancy label R-TAG of the first copy sampling packet by the CPU, and the difference should be maintained equal, otherwise the copy error alarm will be caused. For example, when the second target sampling packet is sampled, the redundancy label can be recorded at the end of the second target sampling packet. For example, the sampling rate is 1000, that is, 1000 samples, if the second target sampling packet of the first sampling falls in the 100th packet, the redundancy label of the first sampling of the second target sampling packet is 100, and the redundancy label of the next sampling of the second target sampling packet is 1100, and so on. That is, when the target sampling rate is 1000, the difference of the sampling points of the adjacent two times of sampling of the original sampling packet is 1000. The R-TAG of the first copy sampling packet of the first sampling is 101, and the R-TAG of the next sampling of the first copy sampling packet is 1101. That is, when the target sampling rate is 1000, the difference of the redundancy labels of the adjacent two times of sampling of the first copy sampling packet is 1000. Further, since the target sampling rate is consistent, when the difference of the redundancy labels between the second target sampling packets of the adjacent two times of sampling is consistent with the difference of the redundancy labels between the first copy sampling packets of the adjacent two times of sampling, it is determined that the packet copying of the copy relay node is correct.

[0090] Alternatively, the second target sampling packet and the first copy sampling packet sampled at adjacent time can also be taken as a group, and the difference of each group of sampling packets is calculated. For example, based on the foregoing example, when the R-TAG of the second target sampling packet of the first sampling is 100, and the R-TAG of the first copy sampling packet of the first sampling is 101, the difference of the sampling packets of the group is 1, when the R-TAG of the second target sampling packet of the second sampling is 1100, and the R-TAG of the first copy sampling packet of the first sampling is 1101, the difference of the sampling packets of the group is also 1, so it can also be determined that the packet copying of the copy relay node is correct.

[0091] In the embodiment, the message replication of the replication relay node is determined to be correct in the case that the redundancy label difference between the second target sampling messages of adjacent two times of sampling is consistent with the redundancy label difference between the first replication sampling messages of adjacent two times of sampling, so that the technical effect that the correctness of the replication relay node in the 802.1CB link can be quickly detected is achieved, and the problem that the correctness of the 802.1CB link is difficult to detect in the related art is solved.

[0092] As an optional implementation, the method further includes the following steps:

[0093] In the case that the redundancy label difference between the second target sampling messages of adjacent two times of sampling is inconsistent with the redundancy label difference between the first replication sampling messages of adjacent two times of sampling, it is determined that the message replication of the replication relay node is abnormal. That is, in the case that the redundancy label difference between the second target sampling messages of adjacent two times of sampling is inconsistent with the redundancy label difference between the first replication sampling messages of adjacent two times of sampling, it is indicated that the replication of the second target sampling message appears repeated replication (i.e., the number of target messages is more than the original message) or missed replication (i.e., the number of target messages is less than the original message), which further causes the above-mentioned situation to occur. For example, taking the target sampling rate of 1000 as an example, if repeated replication occurs, since the sampling rate is unchanged, and the first replication message corresponding to one or more messages is more than one, the redundancy label difference between the first replication sampling messages of adjacent two times of sampling will be less than 1000; if missed replication occurs, since the sampling rate is unchanged, and the first replication message corresponding to one or more messages is missing, the redundancy label difference between the first replication sampling messages of adjacent two times of sampling will be greater than 1000; so that in the case that the sampling point difference between the original sampling messages of adjacent two times of sampling is inconsistent with the redundancy label difference between the first target sampling messages of adjacent two times of sampling, it is determined that the message replication of the replication relay node is abnormal.

[0094] In the case that the at least one first replication sampling message does not have a redundancy label, it is determined that the message replication of the replication relay node is abnormal. That is, the CPU determines that the message replication of the source node is abnormal in the case that the at least one first target sampling message does not have a redundancy label, i.e., the at least one first target sampling message does not carry an R-TAG.

[0095] As shown in Figure 4 According to another aspect of the embodiment of the present application, a method for detecting an 802.1CB link is also provided, which is applied to an elimination end node and includes the following steps:

[0096] In step S402, the redundancy label in each message obtained is stripped to obtain a stripped message corresponding to each message.

[0097] That is, after the elimination end node obtains the message from the source node or other copy relay nodes, etc., the redundant label difference in each obtained message can be stripped to obtain the stripped message corresponding to each message.

[0098] In step S404, all messages are sampled according to the target sampling rate to obtain third target sampling messages.

[0099] In the embodiment, the sampling mode of sampling all messages according to the target sampling rate to obtain the third target sampling messages can refer to the sampling mode of sampling to obtain the first target sampling messages in step S206 of the foregoing embodiment, which will not be described here.

[0100] Further, the collected third target sampling messages are sent to the CPU for comparison with messages obtained by subsequent sampling.

[0101] In step S406, all stripped messages are sampled according to the target sampling rate to obtain stripped sampling messages.

[0102] In the embodiment, the sampling mode of sampling all stripped messages according to the target sampling rate to obtain the stripped sampling messages can refer to the sampling mode of sampling to obtain the original sampling messages in step S204 of the foregoing embodiment, which will not be described here.

[0103] Meanwhile, the stripped sampling messages obtained by sampling are sent to the CPU for comparison with other messages obtained by sampling.

[0113] After obtaining the multiple groups of packets, the elimination relay node can sample at least one group of packets to obtain a fourth target sampling packet corresponding to the at least one group of packets. The sampling manner of obtaining the fourth target sampling packet can refer to the sampling manner of obtaining the second target sampling packet in the foregoing embodiments, and details are not described herein again.

[0114] Further, the collected fourth target sampling packet is sent to the CPU and compared with a packet sampled subsequently.

[0115] In step S504, the merged group of packets is sampled according to the target sampling rate to obtain a merged sampling packet, where the merged group of packets is a group of packets obtained by merging the multiple groups of packets.

[0116] In this embodiment, the elimination relay node can merge the multiple groups of packets to obtain a merged group of packets after removing the redundancy of the packets, and the merged sampling packet can be obtained by referring to the sampling manner of obtaining the second target sampling packet in the foregoing embodiments.

The implementation of determining that the packet merging of the elimination relay node is abnormal in the embodiment can refer to the related implementation of determining that the packet replication of the replication relay node is abnormal in the foregoing embodiment, which will not be described here in detail.

[0121] According to another aspect of the embodiments of the present application, a method for detecting an 802.1CB link applied to any node is further provided, comprising the following steps:

[0122] According to the traffic of the node, all target CB states included in the node are determined, wherein the target CB state comprises at least one of the following: a CB state as a source node, a CB state as a replication relay node, a CB state as an elimination end node, and a CB state as an elimination relay node;

[0123] In a case where the node includes the CB state as the source node, the CB state as the source node is maintained according to the implementation of any one of the foregoing embodiment methods applied to the source node;
