[0058] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0059] It should be noted that the terms "including" and "having" and their variations involved in the documents of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0060] SRv6 is a new generation of IP bearer protocol that can simplify and unify traditional complex network protocols and is the basis for building intelligent IP networks in the 5G and cloud era. SRv6 has the advantages of centralized control, stateless intermediate networks, and good scalability. SR is a protocol designed for software-defined network (SDN) architecture, integrating the advantages of device autonomous forwarding and centralized programming control, and can better realize application-driven networks.

[0061] Service function chain (SFC) is a network service architecture that connects multiple service nodes in sequence to achieve complex network functions. Service chaining is achieved through the path orchestration capability of SRv6 Policy, which can provide different security value-added services and combined services on demand.

[0062] In the related art, when a service chain fails, a service chain bypass can be triggered to avoid traffic interruption due to a link failure. However, the traditional service chain bypass method can only respond to failures passively. Therefore, when the network quality is poor, the service chain bypass cannot be triggered in time, resulting in a decrease in the network performance of the service chain.

[0063] Based on this, the embodiment of the present application provides a service chain bypass method, device, electronic device and storage medium, which generates a first dial test message in response to a first dial test request for a first service node in a service chain, and performs a dial test on the first service node according to the first dial test message to obtain a dial test result of the first service node. If the dial test result indicates that the first service node is in a bypass state, bypass processing is performed on the received first message. By performing a dial test on the first service node, the network quality of the service chain can be actively detected, so that when the network quality of the service chain is poor, the service chain bypass is triggered in time, thereby improving the network performance of the service chain.

[0064] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided by the embodiment of the present application. The method may be executed or executed in parallel in the actual processing process or when the device is executed in accordance with the method sequence shown in the embodiment or drawings.

[0065] Figure 1 A flow chart of a service chain bypass method provided by an embodiment of the present application is shown. Figure 1 As shown, the method comprises the following steps:

[0066] Step S101: generating a first dial test message in response to a first dial test request for a first service node in a service chain.

[0067] Figure 2 A schematic diagram of a service chain is shown exemplarily. Since the service nodes in the service chain are SRv6-unaware SFs (service nodes that cannot identify path information in messages), in order to implement the service chain, it is necessary to configure corresponding proxy nodes for each service node and assign SRv6 SID (proxy segment identifier) ​​to each proxy node.

[0068] After receiving the message sent by the user network, the SRv6 head node encapsulates the message with the segment list of the SRv6 service chain, that is, the path information: SF1 Proxy->SF2 Proxy->SF3 Proxy->SRv6 tail node. Then, each proxy node in the service chain transmits the message according to the path information. When the message is transmitted to the SRv6 tail node, the SRv6 tail node decapsulates the message. Finally, the SRv6 tail node sends the decapsulated message to another user network.

[0069] The following description is made by taking SF2 as the first service node and SF2 Proxy as the proxy node corresponding to the first service node as an example.

[0070] The first proxy node SF2 Proxy may generate a first dial test message in response to the first dial test request for the first service node SF2, so as to prepare for subsequent dial test on the first service node SF2.

[0071] Step S102: perform a dial test on a first service node according to a first dial test message to obtain a first dial test result of the first service node.

[0072] The first dialing test result is used to indicate whether the first service node is in a bypass state.

[0073] Figure 3 An interactive flow chart of a first proxy node performing a dial test on a first service node according to a first dial test message to obtain a first dial test result of the first service node is shown exemplarily. Figure 3 As shown, the process may include the following steps:

[0074] Step S1021: The first proxy node continuously sends a first dialing message to the first service node within a preset time period.

[0075] Exemplarily, the preset duration may be 3 seconds, and the first proxy node SF2 Proxy may continue to send the first dial-test message to the first service node SF2 within 3 seconds. Meanwhile, the first proxy node SF2 Proxy may record the sending timestamp of the first dial-test message.

[0076] Step S1022: The first service node sends a first response message to the first proxy node in response to the first dial test message.

[0077] After receiving the first dial test message sent by the first proxy node SF2 Proxy, the first service node SF2 may process the first dial test message, and after processing, send a first response message to the first proxy node SF2 Proxy.

[0078] Step S1023: If the number of timeout messages in the first response message received by the first proxy node is greater than a first number threshold, it is determined that the first dialing test result is that the first service node is in a bypass state.

[0079] After receiving the first response message, the first proxy node SF2 Proxy records the receiving timestamp of the first response message, thereby determining the time interval between the receiving time of the first response message and the sending time of the first dial test message. If the time interval is greater than the preset first time interval, the first response message is considered to be a timeout message. Furthermore, if the number of timeout messages is greater than the first number threshold within the preset time period, it can be considered that the first dial test result shows that the network quality of the first service node SF2 is poor. At this time, the first service node SF2 is in a bypass state.

[0080] If the number of timed out messages is less than or equal to the first number threshold within a preset time period, it is considered that the network quality of the first service node SF2 is normal and the message can be processed.

[0081] Exemplarily, the preset duration may be set to 3 seconds, the first time interval may be set to 100 milliseconds, and the first quantity threshold may be set to 10.

[0082] Furthermore, if the first dial test result indicates that the first service node SF2 is in bypass state, a bypass mark may be added to the local proxy segment identifier pre-stored in the first proxy node SF2 Proxy, which indicates that the first service node SF2 has poor network quality or fails and cannot perform normal business processing.

[0083] Step S103: Receive a first message and determine whether the first service node is in a bypass state.

[0084] After receiving the first message, the first proxy node SF2 can determine whether the pre-stored local proxy segment identifier is set with a bypass mark. If the local proxy segment identifier of the first proxy node SF2 is set with a bypass mark, it can be determined that the first service node SF2 is in a bypass state.

[0085] Step S104: If the state is bypassed, bypass processing is performed on the first message according to the path information included in the first message.

[0086] In an optional implementation, after the first proxy node SF2 Proxy determines that the first service node SF2 is in a bypass state, the target address field of the path information included in the first message may be modified.

[0087] In a specific implementation, the first proxy node SF2 Proxy may modify the target address field of the path information to the proxy segment identifier of the proxy node SF3Proxy of the second service node SF3 adjacent to the first service node SF2 in the service chain. Then, the target message may be sent based on the proxy segment identifier SF3 Proxy of the proxy node of the second service node.

[0088] The following continues to describe by taking SF2 as the first service node and SF2 Proxy as the proxy node corresponding to the first service node as an example.

[0089] When the first proxy node SF2 Proxy determines that the first service node SF2 is in the bypass state, the target address field of the received first message can be modified to the proxy segment identifier of SF3 Proxy to obtain the target message. Then, the target message can be sent to the second proxy node SF3 Proxy, thereby skipping the first service node SF2 in the bypass state and handing the target message to the second proxy node SF3Proxy for processing.

[0090] Figure 4 Another schematic diagram of a service chain is shown as an example. Figure 4 As shown, after receiving the first message, the first proxy node SF2 Proxy will not send the first message to the first service node SF2 for business processing, but will modify the target address field to the target message of SF3 Proxy and send it to the second proxy node SF3 Proxy, and the second proxy node SF3Proxy will perform the next processing flow.

[0091] In another optional implementation, after the first proxy node determines that the first service node is not in the bypass state, the first proxy node may send the payload portion of the first message to the first service node, and the first service node performs service processing.

[0092] In some embodiments, if the network quality of the first service node SF2 returns to normal, the bypass mark of the local proxy segment identifier may be deleted accordingly, thereby indicating that the first service node SF2 returns to a normal service processing state from a bypass state.

[0093] Figure 5 An interactive flow chart is exemplarily shown in which a first proxy node performs a dial test on a first service node according to a second dial test message to obtain a second dial test result of the first service node. Figure 5 As shown, the process may include the following steps:

[0094] Step S1041: The first proxy node continuously sends a second dialing message to the first service node within a preset time period.

[0095] In some embodiments, the preset duration may be the same as that set when dialing the first service node SF2 according to the first dialing message. For example, the first proxy node SF2 Proxy may continue to send the second wave of dialing messages to the first service node SF2 within 3 seconds. At the same time, the first proxy node SF2 Proxy may record the sending timestamp of the second dialing message.

[0096] In some other embodiments, the preset duration may also be different from the duration set when dialing the first service node SF2 according to the first dialing message. For example, the preset duration may also be set to 4 seconds.

[0097] Step S1042: The first service node sends a second response message to the first proxy node in response to the second dial test message.

[0098] After receiving the second dial detection message sent by the first proxy node SF2 Proxy, the first service node SF2 processes the first dial detection message, and sends a second response message to the first proxy node SF2 Proxy after the processing is completed.

[0099] Step S1043: If the number of timeout messages in the second response message received by the first proxy node is less than the second number threshold, it is determined that the second dialing test result is that the first service node is not in the bypass state.

[0100] After receiving the second response message, the first proxy node SF2 Proxy records the receiving timestamp of the second response message, thereby determining the time interval between the receiving time of the second response message and the sending time of the second dial test message. If the time interval is greater than the preset second time interval, the second response message is considered to be a timeout message. If the number of timeout messages is less than the second number threshold within the preset time length, it can be considered that the second dial test result shows that the network quality of the first service node SF2 has returned to normal, and at this time, the first service node SF2 is not in a bypass state.

[0101] Furthermore, if the second dial test result indicates that the first service node SF2 is not in the bypass state, the bypass mark of the local proxy segment identifier may be deleted, thereby indicating that the first service node SF2 has resumed the normal service processing state and can perform service processing.

[0102] It should be noted that the above only uses the example of the first proxy node being SF2 Proxy. In some embodiments, the first proxy node in the service chain bypass method provided in the present application can be any one of SF1Proxy, SF2Proxy, and SF3Proxy, and the corresponding first service node is the service node corresponding to the proxy node. In specific implementation, some or all of the service nodes in the service chain can be configured according to actual usage requirements, and the present application does not limit this.

[0103] The service chain bypass method provided in the embodiment of the present application generates a first dial test message in response to a first dial test request for a first service node in a service chain, and performs a dial test on the first service node according to the first dial test message to obtain a dial test result of the first service node. If the dial test result indicates that the first service node is in a bypass state, bypass processing is performed on the received first message, and the network quality of the service chain can be actively detected by performing a dial test on the first service node. As a result, not only can the service chain bypass be triggered when a service node in the service chain fails, but the service chain bypass can also be triggered in a timely manner when the network quality of the service chain is poor, thereby improving the network performance of the service chain.
