[0022] In order to make the technical solutions in the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some 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 those of ordinary skill in the art without creative effort should belong to the protection scope of the present application.

[0023] The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings and some embodiments and their application scenarios.

[0024] FIG. 1 shows a flowchart of a traffic detection method 100 provided by an embodiment of the present application, which can be executed by a first node, such as by software or hardware installed in the first node. The first node is a mandatory node defined in a target SRv6 policy. As shown in FIG. 1, the method can include but is not limited to the following steps.

[0025] S110, obtaining information of the target SRv6 policy and a next-hop node.

[0026] The next-hop node is a next-hop mandatory node of the first node in the target SRv6 policy. For example, assuming that the mandatory nodes in the detection path during flow detection are defined in the target SRv6 policy to include node A, node B, and node C, and the detection path is node A→node B→node C, if the first node is node B, then node A is the previous-hop node of the first node, and node C is the next-hop node of the first node.

[0027] In this embodiment, the mandatory node can also be referred to as a waypoint node, and the loose node mentioned later can also be referred to as a non-waypoint node, which is not limited here.

[0028] S120, determining a first traffic detection path between the first node and the next-hop node according to the target SRv6 policy and the next-hop node.

[0029] The first traffic detection path can include the first node, the next-hop node, and at least one second node between the first node and the next-hop node, and the second node is a loose node not defined in the target SRv6 policy. In this embodiment, the loose node supports flow detection technology.

[0030] In an example, when determining the first traffic detection path between the first node and the next-hop node, the first node can calculate the first traffic detection path between the first node and the next-hop node according to a preconfigured topology routing rule, and then send a data traffic statistics message, such as a first traffic detection packet in S130, hop by hop based on the first traffic detection path, to achieve the purpose of flow statistics of data traffic information of each node on the first traffic detection path.

[0031] S130, sending a first traffic detection packet to the next-hop node through the first traffic detection path.

[0032] The first flow detection message carries or includes the data flow information of the first node, and is used to detect the data flow information of each second node on the target SRv6 policy on the first flow detection path.

[0033] For example, assuming that the first flow detection path is first node→node S1→node S2→node S3→next hop node, and nodes S1, S2 and S3 are loose nodes, after the first node sends the first flow detection message to the next hop node through the first flow detection path, when node S1 receives the first flow detection message, it can add or write the detected data flow information of the node to the first flow detection message, and then continue to send the first flow detection message to the next hop node through the first flow detection path. This process is repeated until the next hop node, which is the terminal node or destination node on the first flow detection path, receives the first flow detection message. The first flow detection message can include the data flow information of the first node, the data flow information of node S1, the data flow information of node S2 and the data flow information of node S3. Thus, the data flow detection of the loose nodes on the first flow detection path can be realized, which can be used for subsequent global path optimization and the like.

[0034] In an example, the first flow detection message can further include the identification information of the target SRv6 policy, the node address information of each node on the first flow detection path, and the like.

[0035] In this embodiment, for any first node in the mandatory nodes defined in the target SRv6 policy, the first flow detection path between the first node and the next hop node can be determined according to the target SRv6 policy and the information of the next hop node of the first node, and the first flow detection message is sent to the next hop node through the first flow detection path, so as to realize the flow detection of the loose nodes not defined in the target SRv6 policy.

[0036] In some embodiments, the first node can obtain the information of the target SRv6 policy and the next hop node in various ways in S110. For example, the first node can obtain the target SRv6 policy pre-configured or stored in the local memory, and determine the information of the next hop mandatory node (i.e., the next hop node) of the first node in the target SRv6 policy according to the information of the first node.

[0037] For example, the first node can further obtain the target SRv6 policy and the information of the next-hop node from a network management device. The network management device can be a core control device or a core management device of the multiple mandatory nodes defined in the target SRv6 policy, and can be configured to send control information to the multiple mandatory nodes, receive traffic detection information reported by the multiple mandatory nodes, and perform global routing planning.

[0038] Based on this, for the case that the first node obtains the target SRv6 policy and the information of the next-hop node from the network management device, the implementation manner can include but is not limited to S111-S112 shown in FIG. 2, and the content is as follows.

[0039] S111, receiving a first message from a network management device.

[0040] S112, determining the target SRv6 policy and the information of the next-hop node according to the first message.

[0041] The first message is used to indicate to start traffic detection on the second node corresponding to the target SRv6 policy. In this embodiment, as an implementation manner, the first message can include but is not limited to at least one of 11)-13).

[0042] 11) first indication information, used to indicate to start traffic detection on the second node corresponding to the target SRv6 policy.

[0043] 12) first identification, used to identify the target SRv6 policy.

[0044] 13) second identification, used to identify the next-hop mandatory node of the first node.

[0045] When the first node determines the target SRv6 policy and the information of the next-hop node according to the first message, one or more of the foregoing 11)-13) can be determined.

[0046] For example, assuming that the first message only includes the first indication information, the first node can determine a pre-configured or stored SRv6 policy as the target SRv6 policy, and determine the information of the next-hop mandatory node of the first node in the target SRv6 policy as the information of the next-hop node.

[0047] In an implementation manner, if multiple SRv6 policies are pre-configured or stored in the first node, an SRv6 policy in an up (UP) state among the multiple SRv6 policies can be determined as the target SRv6 policy.

[0048] For example, if the first information only includes the first identifier, the first node can determine the information of the next hop node according to the target SRv6 policy identified by the first identifier.

[0049] For example, if the first information only includes the second identifier, the first node can determine the target SRv6 policy as a pre-configured specific SRv6 policy including a detection path corresponding to the first node and the next hop node, wherein the specific SRv6 policy includes or defines the first node and the next hop node.

[0050] Of course, for the case that the first message includes two or three of the above 11)-13), the first node determines the target SRv6 policy and the information of the next hop node in a manner similar to the above, which will not be repeated here.

[0051] In some embodiments, if none of 11)-13) is included in the first message, the first node can determine a pre-configured or stored SRv6 policy as the target SRv6 policy, and determine the information of the next hop node as the information of the next hop node through which the first node must pass in the target SRv6 policy.

[0052] In some embodiments, for the case that the first node receives the first message from the network management device in S111, the network management device can send the first message to each of the nodes defined in the target SRv6 policy to instruct each of the nodes to start traffic detection on the second node corresponding to the target SRv6 policy, i.e., to detect data traffic information of the second node, in the case that it is determined to start traffic detection on the second node corresponding to the target SRv6 policy, wherein the first node is any one of the nodes defined in the target SRv6 policy.

[0053] In an example, the first message for instructing to start traffic detection on the second node corresponding to the target SRv6 policy can include: the first message for instructing the first node to determine a first traffic detection path between the first node and a next hop node, and to detect data traffic information of each of the second nodes on the target SRv6 policy on the first traffic detection path through a first traffic detection packet, wherein the first traffic detection path is a detection path between the first node and the next hop node, and the next hop node is a next hop node through which the first node must pass in the target SRv6 policy.

[0054] In some embodiments, the network management device determines to start traffic detection on the second node corresponding to the target SRv6 policy in various manners.

[0055] For example, assuming that a target traffic detection switch is deployed in the network management device, the network management device can determine to start traffic detection on the second node corresponding to the target SRv6 policy in response to the target traffic detection switch being turned on, where the target traffic detection switch being turned on indicates that data traffic information of the second node is detected. In an example, the target traffic detection switch can be a physical switch, control signaling or instructions, etc., which is not limited herein.

[0056] For another example, assuming that a target traffic detection switch is deployed in one or more of the nodes defined in the target SRv6 policy, when any of the nodes (e.g., the first node) with the traffic detection switch is turned on in response to the target traffic detection switch, a third message can be sent to the network management device to request traffic detection on the second node corresponding to the target SRv6 policy. Correspondingly, the network management device determines to start traffic detection on the second node corresponding to the target SRv6 policy according to the third message when the third message sent by any of the first nodes is received.

[0057] As an implementation manner, the network management device determines to start traffic detection on the second node corresponding to the target SRv6 policy according to the third message can include: determining the SRv6 policy corresponding to the identification information of the first node as the target SRv6 policy according to the identification information of the first node carried in the third message.

[0058] That is, the network management device preconfigures or stores one or more SRv6 policies, and when the network management device receives the third message, the SRv6 policy corresponding to the identification information of the first node can be selected from the preconfigured or stored one or more SRv6 policies as the target SRv6 policy.

[0059] The “SRv6 policy corresponding to the identification information of the first node” can be understood as that the identification information of the first node is included in the information of the nodes defined in the SRv6 policy, or there is an association relationship between the SRv6 policy and the identification information of the first node, etc., which is not limited herein.

[0060] In some embodiments, if the network management device determines that there are multiple SRv6 policies corresponding to the identification information of the first node, the target SRv6 policy is the SRv6 policy in an active state among the multiple SRv6 policies.

[0061] In some embodiments, for the case that the network device sends the first message to each of the nodes defined in the target SRv6 policy, for the nodes belonging to the same Segment Routing Header (SRH) path, considering that the last node in an SRH path does not have a next hop node, the network device can send the first message to all the nodes in the SRH path except the last node. Of course, if the network device sends the first message to each of the nodes in the SRH path, the last node in the SRH path can ignore the first message or report the data flow information of the node to the network device in the form of a second message, which is not limited herein.

[0062] In the foregoing, the first node is the starting node for data flow detection, and is used to perform the flow detection method described in S110-S130. In addition to being the starting node for data flow detection, the first node can also be the terminal node or destination node for data flow detection. For example, as shown in FIG. 3, when the first node is the terminal node or destination node, the process of data flow detection that can be implemented by the first node can include but is not limited to S310-S320.

[0063] S310, receiving a second flow detection packet.

[0064] The second flow detection packet is a detection packet sent by a previous hop node to the first node through a second flow detection path. The second flow detection path is a flow detection path between the previous hop node and the first node, which is determined by the previous hop node according to the target SRv6 policy and information of the first node. The previous hop node is the previous hop node of the first node on the target SRv6 policy.

[0065] S320, in a case that the first node is determined to be the destination address corresponding to the second flow detection packet according to the second flow detection packet, determining the data flow information of the previous hop node on the target SRv6 policy and the data flow information of each third node on the target SRv6 policy on the second flow detection path according to the second flow detection packet. The third node is a loose node not defined in the target SRv6 policy.

[0066] Exemplarily, assuming that the second traffic detection path determined by the previous hop node of the first node is: previous hop node→third node→first node, the data traffic information of the previous hop node and the data traffic information of the third node are included in the second traffic detection packet received by the first node, so that the traffic detection for the third node, which is a loose node, can be completed.

[0067] It is worth noting that the second traffic detection path, the second traffic detection packet, and the third node mentioned in the foregoing S310-S320 are similar to the first traffic detection path, the first traffic detection packet, and the second node involved in the foregoing S110-S130, and the only difference is that the second traffic detection path is determined by the previous hop node of the first node, and the second traffic detection packet is sent by the previous hop node to the first node through the second traffic detection path, for the data traffic information of the loose node between the previous hop node and the first node, while the first traffic detection path is determined by the first node, and the first traffic detection packet is sent by the first node to the next hop node through the first traffic detection path, for the data traffic information of the loose node between the first node and the next hop node, therefore, as to the second traffic detection path, the second traffic detection packet, and the third node mentioned in the foregoing S310-S320, reference can be made to the relevant description of the first traffic detection path, the first traffic detection packet, and the second node in the foregoing S110-S130, which will not be repeated here.

[0068] In some embodiments, after performing S320, the first node can further obtain the data traffic information of the first node on the target SRv6 policy, and send a second message to the network management device, the second message including the data traffic information of the first node on the target SRv6 policy, the data traffic information of the previous hop node on the target SRv6 policy, and the data traffic information of each third node on the target SRv6 policy on the second traffic detection path.

[0069] That is, as the terminal node or the destination node on the second traffic detection path, the first node can collect the data traffic information of each node detected by the second traffic detection packet and the data traffic information of the node itself, and then report the second signal to the network management device, so that the network management device can perform at least one of data traffic control and network path optimization according to the second message, thereby improving network performance and meeting the higher requirements of SRv6 on path selection of control traffic.

[0070] The foregoing data flow detection scheme provided by the embodiments of the present application, the network management device detects the data flow information of the mandatory node defined in the SRv6 policy and the data flow information of the loose node not defined in the SRv6 policy, so that the network management device can master the full path state based on the reported data flow information of the mandatory node and the data flow information of the loose node, and then optimize the path according to the real-time network state, realize more fine traffic engineering and path optimization, and meet the higher requirements proposed by the SRv6 for the path selection of the control flow.

[0071] The technical scheme provided by the present application can be applied to but not limited to the SRv6 scenario.

[0072] Based on the foregoing description of the flow detection method provided by the present application, for the convenience of understanding, the implementation process thereof will be further exemplarily described in combination with Example 1, and the content is as follows.

[0073] Example 1

[0074] As shown in FIG. 4, it is assumed that for a layer 3 virtual private network (L3 Virtual Private Network, L3VPN) or layer 2 Ethernet Virtual Private Network (L2EVPN), there is an SRv6 policy path, that is, node B→node C→node D→node E→node F, wherein node B, node D, and node F are mandatory nodes defined in the SRv6 policy, that is, nodes included in the SRH path defined in the SRv6 policy, and node C and node E are loose nodes not defined in the SRv6 policy, and node B, node C, node D, node E, and node F all support the flow detection technology. Then, the data flow detection process for the loose nodes in the SRv6 policy path is as follows.

[0075] 1) Node F sends a third message to the network management device in response to the target flow detection switch being turned on, to request to perform flow detection on the second node corresponding to the target SRv6 policy.

[0076] 2) After receiving the third message, the network management device finds the SRv6 policy including the identifier information of node F as the target SRv6 policy from all preconfigured SRv6 policies according to the identifier information of node F carried in the third message.

[0077] 3) The network management device determines the mandatory nodes defined in the target SRv6 policy, such as node B, node D, and node F, and determines the next hop node of each mandatory node, such as the next hop node of node B being node D and the next hop node of node D being node F.

[0078] 4) The network management device sends a first message to node B, node D and node F respectively, to indicate that the target traffic detection switch is turned on.

[0079] The first message can include at least one of first indication information, a first identifier and a second identifier. The first indication information is used to indicate that the traffic detection for the target SRv6 policy corresponding to the second node is turned on. The first identifier is used to identify the target SRv6 policy. The second identifier is used to identify the next hop node of the mandatory node.

[0080] 5) Taking node B as an example, after receiving the first message, node B determines the target SRv6 policy and the information of the next hop node of node B, i.e., the information of node D, according to the first message.

[0081] 6) Node B determines the traffic detection path 1 from node B to node D, i.e., node B→node C→node D shown in FIG. 4, according to the target SRv6 policy and the information of node D.

[0082] 7) Node B sends a traffic detection packet 1 to node D through the traffic detection path 1, wherein the traffic detection packet 1 includes the data traffic information of node B.

[0083] 8) Node C, after receiving the traffic detection packet 1 from node B, writes the data traffic information of node C into the traffic detection packet 1 and then sends the traffic detection packet 1.

[0084] 9) Node D, after receiving the traffic detection packet 1, determines the data traffic information of node B, the data traffic information of node C and the data traffic information of node D according to the traffic detection packet 1, if node D is determined to be a terminal node or a target node according to the destination address carried in the traffic detection packet 1.

[0085] 10) Node D sends a second message to the network management device, wherein the second message includes the data traffic information of node B, the data traffic information of node C and the data traffic information of node D.

[0086] For node D, similar to the traffic detection process between node B and node D, node D can determine the traffic detection path 2, i.e., node D→node E→node F shown in FIG. 4, after receiving the first message, and sends a traffic detection packet to node F through the traffic detection path 2, to realize the detection of the data traffic of each node on the traffic detection path 2. Node F reports the detected data traffic information of node D, the data traffic information of node E and the data traffic information of node F to the network management device in the form of a second message.

[0087] For the node F, after receiving the first message, since it is determined according to the first message that there is no next hop node to be passed through, the first message can be ignored, or the node F can also count the data flow information of the node and report the data flow information to the network management device.

[0088] In addition, as an implementation manner, the network management device can also not send the first message to the node F.

[0089] The foregoing 1)-10) can realize the data flow detection of the loose node on the SRv6 policy A path in the example 1, so that the network management device can master the whole path state according to the detected data flow information, and further optimize the path according to the real-time network state, realize more fine traffic engineering and path optimization, and meet the higher requirements of SRv6 on the path selection of control flow.

[0090] In addition, the foregoing process provided in the example 1 can refer to the related description in the foregoing method embodiment 100 and achieve the same or corresponding technical effects. To avoid repetition, it will not be repeated here. In addition, the example 1 can include more or fewer steps than the foregoing 1)-10), which is not limited here.

[0091] FIG. 5 shows a flowchart of a flow detection method 500 provided by the embodiments of the present application. The method can be executed by a network management device and can be executed by software and / or hardware installed in the network management device. As shown in FIG. 5, the method 500 can include but is not limited to the following steps.

[0092] S510, determining to start flow detection for a second node corresponding to a target SRv6 policy, the second node being a loose node not defined in the target SRv6 policy.

[0093] S520, sending a first message to each mandatory node defined in the target SRv6 policy.

[0094] For any first node in the each mandatory node, the first message is used to indicate that the first message is used to indicate to start flow detection for the second node corresponding to the target SRv6 policy.

[0095] In some embodiments, the first message is configured to instruct to start the traffic detection on the second node corresponding to the target SRv6 policy, including: the first message is configured to instruct the first node to determine a first traffic detection path between the first node and a next hop node, and to detect data traffic information of each second node on the target SRv6 policy on the first traffic detection path through a first traffic detection packet, the first traffic detection path being a detection path between the first node and the next hop node, and the next hop node being a next hop node of the first node in the target SRv6 policy.

[0096] In some embodiments, the first message includes at least one of: first indication information configured to instruct to start the traffic detection on the second node corresponding to the target SRv6 policy; a first identifier configured to identify the target SRv6 policy; and a second identifier configured to identify the next hop node of the mandatory node.

[0097] In some embodiments, the determining to start the traffic detection on the second node corresponding to the target SRv6 policy includes: in response to a target traffic detection switch being turned on, determining to start the traffic detection on the second node corresponding to the target SRv6 policy, the target traffic detection switch being turned on being configured to represent that the data traffic information of the second node is detected.

[0098] In some embodiments, the determining to start the traffic detection on the second node corresponding to the target SRv6 policy includes: receiving a third message sent by any first node of the mandatory nodes, the third message being configured to request to perform the traffic detection on the second node corresponding to the target SRv6 policy; and determining to start the traffic detection on the second node corresponding to the target SRv6 policy according to the third message.
