[0038] In order to make the technical solutions in the present application or prior art clearer, the accompanying drawings needed in the embodiments or prior art description will be briefly introduced. Obviously, the accompanying drawings in the following description are some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative effort on the basis of these drawings.

[0039] The large flow and low delay characteristics brought by the evolution of the Internet greatly improve the sensitivity of the operator network, and slight link quality jitter will have a serious impact. The existing link quality detection scheme has the following defects:

[0040] 1) Probe dialing: The probe dialing scheme cannot meet the requirements of full member detection, and in some non-path member failure scenarios, it may also cause maintenance personnel to misjudge. In the equivalent route scenario of the operator network route load balancing, the probe dialing will also appear the dialing path uncertain situation, in addition, the probe dialing is limited by the performance of the network equipment;

[0041] 2) Device view: through Simple Network Management Protocol (SNMP) or maintenance personnel manually to the network device alarm, the cyclic redundancy check (CRC) under the port of the wrong package statistics, also exist monitoring efficiency, scene coverage is not complete, port CRC error code statistics can not cover the flash scene.

[0042] In the process of maintaining the existing network, the end user often feedbacks that the network quality is poor, but the network test result is normal. After the user complains, a large amount of manpower is consumed to carry out on-site packet capture and application layer analysis, which not only cannot quickly locate the problem, but also is prone to deviation in the positioning direction, causing the fault handling time delay, and the fine maintenance of the network cannot be realized.

[0043] Therefore, the embodiment of the present application provides a link quality detection method, device, equipment, storage medium and program product, by configuring a multicast protocol, configuring parameters, forwarding paths and load sharing rules of a detection multicast flow, generating a plurality of detection multicast flows, forwarding the corresponding detection multicast flow to all Member links of each target Trunk link, monitoring the transmission quality of each detection multicast flow, comparing the monitoring result with the target network device log, and determining the port that occurs a fault. The present application can realize accurate identification and rapid positioning of the subtle difference of the whole link.

[0044] Figure 1 The structure diagram of the link quality detection system provided by the embodiment of the present application is shown in the figure. Figure 1 As shown, a link quality detection system is provided, which comprises a multicast flow generator, a multicast flow quality probe, a flow control module, a topology input module, a cooperative component and a high-density link monitoring module.

[0045] The multicast flow generator is configured to generate a plurality of detection multicast flows, and forward the corresponding detection multicast flow to all Member links of each target Trunk link.

[0046] The flow control module is configured to configure a multicast protocol, configure parameters, forwarding paths and load sharing rules of a detection multicast flow, so that the detection multicast flow can be distributed among the Member links of each target Trunk link according to the load sharing rules.

[0047] The topology input module is configured to obtain a target network device log, compare the monitoring result with the target network device log, and determine the port that occurs a fault.

[0048] The cooperative assembly is used for configuring and functionally combining the drainage control module, the multicast stream generator and the multicast stream quality probe, realizing cooperation and consistency of test paths, test multicast streams and corresponding monitoring tasks, and synchronizing task information to the high-density link monitoring module.

[0049] The high-density link monitoring module is used for determining the association of the multicast stream quality probe reporting data with test tasks and monitoring tasks, and realizing accurate identification and positioning of poor-quality links based on the mapping relationship between multicast stream quality probe deployment points and network topology.

[0050] It can be understood that by synchronously reporting the multicast stream quality probe detection result, the mapping relationship between the detection multicast stream and the corresponding physical link to the high-density link monitoring module, the member-level physical link of the whole network can be monitored, high-sensitivity monitoring and high-density detection are realized, and thus the network quality requirements of industrial internet, ultra-high-definition video and virtual reality (VR) services can be met.

[0051] Figure 2 A flowchart of a link quality detection method provided by the embodiment of the present application is shown in Fig. 1. Figure 2 As shown in Fig. 1, a link quality detection method is provided, which includes the following steps: step 210, step 220 and step 230. The method flow steps are only used as one possible implementation of the present application.

[0052] In step 210, a multicast protocol is configured, parameters, forwarding paths and load sharing rules of a detection multicast stream are configured, so that the detection multicast stream can be distributed among the Member links of each target Trunk link according to the load sharing rules.

[0053] The Trunk link refers to a high-capacity aggregation link in a network for transmitting data, which is used to connect two network devices (such as switches or routers). The Trunk link is composed of multiple Member links and can carry a large amount of data traffic to realize high-speed data transmission and communication between network devices.

[0054] The Member link is a single member link of the Trunk link, which is used to connect two network device ports.

[0055] Figure 3 A structure diagram of a target network to be detected provided by the embodiment of the present application is shown in Fig. 2. Figure 3As shown, the target network to be detected includes six remote terminals (RTs), and the six RTs form a "mouth-shaped" network. The uplink, downlink and crosslink of the backbone network are all configured with multi-Member Trunks. For example, a Trunk35 link is configured between RT05 and RT03, and the Trunk35 link includes three Members, i.e., Member-1, Member-2 and Member-3.

[0056] For example, the normal forwarding path of the multicast stream to be detected is "RT01-RT03", and the standby forwarding path is "RT01-RT02-RT04-RT03" via the logical link trunk13 (the actual traffic load is on three members, and the traffic carried by the three members is different).

[0057] Optionally, each network device port enables the PIM protocol; taking the unidirectional RT03 as an example, the uplink Trunk13 and the crosslink Trunk34 are monitored in the full path.

[0058] For example, if the link quality of the Trunk34 needs to be tested, the PIM protocol of the trunk13 of the RT03 is disabled, and the multicast stream can be forwarded according to the forwarding path "RT01-RT02-RT04-RT03".

[0059] In some embodiments, the multicast protocol is configured, including:

[0060] The protocol-independent multicast sparse mode PIM-SM protocol is configured on the bearer network device of the target network to be detected.

[0061] The Internet Group Management Protocol IGMP is configured on the access layer device of the target network.

[0062] The PIM-SM protocol establishes and maintains the multicast tree by using the "join pruning" mechanism, ensures that the multicast data is only copied and forwarded where there are receivers, and thus can greatly reduce network congestion.

[0063] The IGMP realizes the management function of group members by sending messages between receiver hosts and multicast routers, and can effectively send data streams to multiple users in scenarios such as video conferencing, online games, streaming media broadcasting and the like which need to send the same content to multiple receivers.

[0064] In some embodiments, the parameters of the multicast stream to be detected include the code rate and network information, and the network information includes the destination Internet Protocol IP and the destination port. The load sharing rule includes flow-based load.

[0065] The code rate of the multicast stream refers to the rate of transmitting the multicast stream, such as 2 Mbps, 8 Mbps, or 16 Mbps.

[0066] It should be noted that the number of forwarding multicast messages per unit time of the link can be adjusted by changing the code rate, so as to adjust the fine degree of link quality monitoring. By adjusting the multicast message encapsulation (such as destination IP and destination port), the mapping relationship between the member in the trunk and the multicast stream can be determined.

[0067] The per-flow load balancing refers to classifying the multicast messages into different data streams according to certain rules (such as five-tuple: source IP address, destination IP address, protocol number, source port number, and destination port number), and the messages of the same data stream are sent on the same link.

[0068] It can be understood that the per-flow load balancing can meet the forwarding of multicast messages with the same attribute on the same interface, and can maximize the guarantee that the multicast messages will not be out of order at the receiving end.

[0069] In some embodiments, the parameters of the detected multicast stream, the forwarding path, and the load balancing rule are configured, including:

[0070] The parameters of the detected multicast stream are configured, and a corresponding multicast group is configured for each target Trunk link.

[0071] The enablement and disablement of the protocol-independent multicast (PIM) of the ports of each network device of the target network to be detected are performed, so that the detected multicast stream can cover each target Trunk link.

[0072] The load balancing rule is configured on the port of each network device.

[0073] Optionally, the multicast stream of a certain code rate can be configured with different multicast groups (destination IP and destination port) and multiplexed into multiple detected multicast streams.

[0074] Step 220, generating multiple detected multicast streams, forwarding the corresponding detected multicast stream to all Member links of each target Trunk link, monitoring the transmission quality of each detected multicast stream, and obtaining a monitoring result, the monitoring result including the mapping relationship between each detected multicast stream and each Member link.

[0075] Optionally, the multicast stream generator selects the code rate of the detected multicast stream according to the detection fine degree, and forms m detected multicast streams by encapsulating different multicast message headers (multicast group IP and port number), m being a natural number greater than or equal to 1, and m being greater than a preset threshold.

[0076] Optionally, the number of multicast streams detected in the multicast group corresponding to each target Trunk link is greater than the total number of Member links of each target Trunk link.

[0077] In step 230, the target network device log is acquired, the monitoring result is compared with the target network device log, and the faulty port is determined.

[0078] The target network device log includes port state changes, error information, etc., and the specific device, specific port and specific time of the down event can be obtained from the target network device log.

[0079] Optionally, the log information is acquired from the target network device using appropriate network management tools or commands.

[0080] In the embodiment of the application, by configuring the multicast protocol, configuring the parameters of the detected multicast stream, the forwarding path and the load sharing rule, generating multiple detected multicast streams, forwarding the corresponding detected multicast stream to all Member links of each target Trunk link, monitoring the transmission quality of each detected multicast stream, comparing the monitoring result with the target network device log, and determining the faulty port, the fine and accurate identification and rapid positioning of the whole link can be realized.

[0081] It should be noted that each embodiment of the application can be freely combined, the order can be changed or the embodiments can be executed independently, and the fixed execution order is not required.

[0082] In some embodiments, the monitoring result is compared with the target network device log to determine the faulty port, including:

[0083] Based on the monitoring result, the target detected multicast stream with quality difference is determined.

[0084] The target moment when the target detected multicast stream has quality difference is determined, and the log of the target network device corresponding to the target detected multicast stream at the target moment is acquired.

[0085] The monitoring result of the target detected multicast stream at the target moment is compared with the log of the target network device corresponding to the target detected multicast stream at the target moment, a mapping relationship between the target detected multicast stream and the target Member link is constructed, and the faulty port is determined.

[0086] Table 1 is a mapping table of the detected multicast stream and the Member link provided by the embodiment of the application, as shown in Table 1, Trunk 13 includes three Member links, and the port of each Member link corresponds to a detected multicast stream.

[0087] Table 1 is a mapping table of the detected multicast stream and the Member link provided by the embodiment of the application, as shown in Table 1, Trunk 13 includes three Member links, and the port of each Member link corresponds to a detected multicast stream.

[0088]

[0089] For example, by comparing the logs of RT03, the up and down events of Member-1 in Trunk13 are identified, and multicast stream quality probe A finds that the multicast stream "239.255.0.1:8084" has poor quality with packet loss, and it can be directly judged that the "100G1 / 0 / 0 / 0" physical link of RT03 has failed.

[0090] It can be understood that by comparing the monitoring results with the device logs, the faulty port can be more accurately determined, the time and workload of troubleshooting can be reduced, and the efficiency of fault handling can be improved.

[0091] In some embodiments, a plurality of detection multicast streams are generated, a corresponding detection multicast stream is forwarded to all Member links of each target Trunk link, the transmission quality of each detection multicast stream is monitored, and monitoring results are obtained, including:

[0092] Based on the parameters of the detection multicast stream, a multicast stream generator is used to generate a plurality of detection multicast streams;

[0093] A corresponding detection multicast stream is forwarded to all Member links of each target Trunk link;

[0094] A multicast stream quality probe is used to monitor and evaluate the transmission quality of each detection multicast stream from multiple aspects, and monitoring results are obtained.

[0095] Optionally, the protocol encapsulation format of the detection multicast stream carrying the video stream is Moving Picture Experts Group Transport Stream (MPEG-TS), Real-time Transport Protocol (RTP), or User Datagram Protocol (UDP).

[0096] The UDP message has no retransmission mechanism, which ensures the sensitivity of the multicast message to link quality. Once a link quality problem occurs (such as packet loss or packet error), the multicast message will not be blocked due to the disaster recovery mechanism of the protocol itself.

[0097] The RTP message contains a sequence field that can be continuously circulated between 0 and 65535. The RTP message also contains a Real-Time Control Protocol (RTCP) message, which can be used to judge network quality.

[0098] Optionally, each RTP message encapsulates 7 MPEG-MTS messages, with the sequence numbers of the 7 MTS messages cycling consecutively between 0 and 15.

[0099] Understandably, by generating multiple detection multicast streams and monitoring their transmission quality, the performance of network transmission can be monitored in real time, which helps to promptly identify network problems and respond quickly. By using multicast stream quality probes to monitor and evaluate the transmission quality of each detection multicast stream from multiple levels, a comprehensive understanding of various aspects of network transmission can be obtained, including indicators such as packet loss rate, latency, and bandwidth utilization. By correlating the monitoring results with the target Trunk and Member links, the location of network transmission problems can be accurately pinpointed, which helps to quickly locate and resolve problems.

[0103] The link detection unit 420 is used to generate multiple detection multicast streams, forward the corresponding detection multicast streams to all Member links of each target Trunk link, monitor the transmission quality of each detection multicast stream, and obtain monitoring results.

[0104] The fault location unit 430 is used to acquire the target network device logs, compare the monitoring results with the target network device logs, and determine the port where the fault occurred.

[0105] Optionally, the monitoring results are compared with the target network device logs to determine the port where the fault occurred, including:

[0106] Based on the monitoring results, the target detection multicast streams that have poor quality were identified;
