[0001] The present application relates to the field of network communication technology, and in particular to a method, device, system, equipment and medium for multicast data transmission. Background Art

[0002] There are many problems with traditional multicast methods: 1. With the continuous expansion of network scale and the increasing number of multicasts, network devices, such as routers, need to maintain more status information during multicast data transmission, which significantly increases the burden on network devices and makes them difficult to expand; 2. Network devices need to rely on specific multicast protocols, such as the PIM protocol (Protocol Independent Multicast), and the configuration of multicast protocols is relatively complex; 3. Network devices lack access control and authentication mechanisms for device nodes during multicast data transmission, making it difficult to prevent malicious device nodes from joining or eavesdropping, posing potential security risks. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a multicast data transmission method, apparatus, system, device and medium to achieve the technical effect of effectively improving the efficiency of multicast data transmission.

[0004] In a first aspect, an embodiment of the present application provides a multicast data transmission method, including:

[0005] Obtain target multicast data; wherein the SRv6 segment routing list carried by the target multicast data is embedded with identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to identification information of a node on the target multicast path;

[0006] Traversing each node on the target multicast path, when the current node is a forwarding node, controlling the forwarding node to forward the target multicast data according to the routing path corresponding to the identification information of the forwarding node, and when the current node is a receiving node, controlling the receiving node to receive the target multicast data.

[0007] In the above implementation process, by obtaining the target multicast data, since the SRv6 segment routing list carried by the target multicast data is embedded with the identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path, the forwarding node on the target multicast path can be directly controlled to forward the target multicast data according to the routing path corresponding to the forwarding node, without maintaining a large amount of state information, while reducing the difficulty of routing search, thereby effectively improving the efficiency of multicast data transmission.

[0008] Furthermore, before acquiring the target multicast data, the method further includes:

[0009] A multicast path from a source node to each receiving node is planned according to the network topology structure to obtain the target multicast path.

[0010] In the above implementation process, by planning the multicast path from the source node to each receiving node according to the network topology structure, the target multicast path is obtained. The target multicast path can be reasonably and accurately planned considering the network topology structure, which is conducive to further improving the multicast data transmission efficiency.

[0011] Furthermore, the method further comprises:

[0012] Determine whether each node on the target multicast path is an abnormal node;

[0013] In the case that at least one node on the target multicast path is an abnormal node, the at least one node is removed, and the target multicast path is replanned, and the target multicast path is updated to the replanned target multicast path.

[0014] In the above implementation process, when it is determined that at least one node on the target multicast path is an abnormal node, at least one node is removed, and the target multicast path is replanned, and the target multicast path is updated to the replanned target multicast path. When at least one node on the target multicast path is abnormal, the target multicast path can be replanned to ensure that the target multicast data is successfully transmitted according to the target multicast path, which is conducive to further improving the efficiency of multicast data transmission.

[0015] Further, the determining whether each node on the target multicast path is an abnormal node includes:

[0016] For each node on the target multicast path, determining the network connection status of the node;

[0017] When the node is in an offline state, the node is determined to be an abnormal node.

[0018] In the above implementation process, for each node on the target multicast path, when it is determined that the network connection state of the node is offline, the node is determined to be an abnormal node, and whether the node is an abnormal node can be accurately judged according to the network connection state of the node.

[0019] Furthermore, the method further comprises:

[0020] The target multicast path is adjusted according to the data transmission performance index fed back by each receiving node on the target multicast path, and the target multicast path is updated to the adjusted target multicast path.

[0021] In the above implementation process, the target multicast path is adjusted according to the data transmission performance index fed back by each receiving node on the target multicast path, and the target multicast path is updated to the adjusted target multicast path. The data transmission performance index of this multicast can be evaluated to optimize and adjust the target multicast path, so as to ensure that the next target multicast data can be transmitted according to the adjusted target multicast path when multicast is performed for each receiving terminal next time, thereby facilitating the improvement of the multicast data transmission efficiency.

[0038] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0039] It should be noted that in the description of this application, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance. At the same time, the step numbers in the text are only for the convenience of explaining the embodiments of this application and do not serve to limit the order of execution of the steps.

[0040] In the related technologies, the traditional multicast method has many problems: 1. With the continuous expansion of network scale and the continuous increase in the number of multicasts, network devices, such as routers, need to maintain more status information during the multicast data transmission process, resulting in a significant increase in the burden on network devices and difficulty in expansion; 2. Network devices need to rely on specific multicast protocols, such as the PIM protocol (Protocol Independent Multicast), and the configuration of multicast protocols is relatively complex; 3. Network devices lack access control and authentication mechanisms for device nodes during multicast data transmission, making it difficult to prevent malicious device nodes from joining or eavesdropping, posing potential security risks.

[0041] To this end, the present application proposes a multicast data transmission method, which obtains the target multicast data. Since the SRv6 segment routing list carried by the target multicast data is embedded with the identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path, the forwarding node on the target multicast path can be directly controlled to forward the target multicast data according to the routing path corresponding to the forwarding node, without maintaining a large amount of status information, while reducing the difficulty of routing search, thereby effectively improving the efficiency of multicast data transmission.

[0042] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0043] The method provided in the embodiment of the present application can be executed by a related terminal device, and the following description will be given using a network device as an example of the execution subject.

[0044] Please see Figure 1 , Figure 1 A flowchart of a multicast data transmission method provided in the first embodiment of the present application. The first embodiment of the present application provides a multicast data transmission method, including steps S101 to S102:

[0045] S101. Obtain target multicast data; wherein the SRv6 segment routing list carried by the target multicast data is embedded with identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to identification information of a node on the target multicast path.

[0046] As an example, in a scenario where the same data needs to be transmitted to multiple different receiving terminals, the network device obtains target multicast data, wherein the SRv6 segment routing list carried by the target multicast data is embedded with identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path.

[0047] It should be noted that IPv6 (Internet Protocol Version 6) is a new generation of network protocol designed by the Internet Engineering Task Force. SRv6 (Segment Routing IPv6) is simply a combination of SR (Segment Routing) and IPv6. It is a protocol designed based on the source routing concept to forward IPv6 data on the network. SRv6 inserts an SRH (Segment Routing Header) into the IPv6 data. The SRH contains an SL (Segment List) composed of one or more SIDs (Segment Identifiers) with IPv6 address characteristics in an ordered manner, thereby obtaining SRv6 data. The destination address of the SRv6 data will be updated segment by segment according to the SL, thereby completing hop-by-hop forwarding and realizing segment routing.

[0048] SRv6 uses the richness of IPv6 address space to embed path information into the header of IPv6 data, eliminating the need for network devices to maintain a large amount of status information, greatly simplifying network configuration and management. This mechanism not only reduces protocol overhead, but also supports advanced functions such as traffic engineering and path programming, and can flexibly respond to complex business needs. In addition, SRv6 is easy to integrate and expand, suitable for new network architectures such as SDN (Software Defined Network) and CDN (Content Delivery Network), and promotes the development of network automation and intelligence.

[0049] In an optional implementation of this embodiment, the obtaining of target multicast data includes: obtaining original multicast data and a target multicast path; wherein the original multicast data is IPv6 data; embedding identification information of each node on the target multicast path in an SRv6 segment routing list carried by the original multicast data, so that a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path, and obtaining the target multicast data.

[0050] As an example, in a scenario where the network device needs to transmit the same data to multiple different receiving terminals, the network device obtains the original multicast data from the multicast data source, wherein the original multicast data is IPv6 data encapsulated by the multicast data source, and determines the target multicast path from the network device to each receiving terminal. The SRv6 protocol is adopted to insert a segment routing extension header containing an SRv6 segment routing list into the original multicast data, so that the original multicast data carries the SRv6 segment routing list, and the identification information of each node on the target multicast path is embedded in the SRv6 segment routing list carried by the original multicast data, so that a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path, and the target multicast data is obtained.

[0051] It should be noted that each node on the target multicast path represents each terminal that the target multicast path passes through, such as a forwarding terminal and a receiving terminal.

[0052] In practical applications, the identification information of each node on the target multicast path may be an IP address (Internet Protocol Address) of each terminal passed through on the target multicast path.

[0053] S102, traversing each node on the target multicast path, and when the current node is a forwarding node, controlling the forwarding node to forward the target multicast data according to the routing path corresponding to the identification information of the forwarding node, and when the current node is a receiving node, controlling the receiving node to receive the target multicast data.

[0054] As an example, after acquiring the target multicast data, the network device parses the identification information of each node on the target multicast path from the target multicast data, as well as the correspondence between each segment routing path in the segment routing list and the identification information of each node on the target multicast path.

[0055] Traverse each node on the target multicast path, and when the current node is a forwarding node, determine the routing path corresponding to the identification information of the forwarding node, and control the forwarding node to forward the target multicast data according to the determined routing path; when the current node is a receiving node, control the receiving node to receive the target multicast data, so that the receiving node can continue to process the target multicast data according to actual application requirements.

[0056] In the embodiment of the present application, by acquiring the target multicast data, since the SRv6 segment routing list carried by the target multicast data is embedded with the identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path, the forwarding node on the target multicast path can be directly controlled to forward the target multicast data according to the routing path corresponding to the forwarding node, without maintaining a large amount of state information, while reducing the difficulty of routing search, thereby effectively improving the efficiency of multicast data transmission.

[0057] In an optional embodiment, before acquiring the target multicast data, the method further includes: planning a multicast path from the source node to each receiving node according to the network topology structure to obtain the target multicast path.

[0058] As an example, in a scenario where the network device needs to transmit the same data to multiple different receiving terminals, the network device plans a multicast path from the source node to each receiving node according to the network topology where the network device and the multiple receiving terminals are located to obtain a target multicast path.

[0059] It should be noted that the source node represents a network device.

[0060] In practical applications, the network device may plan a multicast path from a source node to each receiving node using a shortest path tree algorithm or a minimum spanning tree algorithm according to the network topology where the network device and multiple receiving terminals are located, and obtain a target multicast path.

[0061] The embodiment of the present application plans a multicast path from a source node to each receiving node according to a network topology structure to obtain a target multicast path. This can reasonably and accurately plan the target multicast path considering the network topology structure, which is beneficial to further improve the efficiency of multicast data transmission.

[0062] In an optional embodiment, the method further includes steps S103-S104:

[0063] S103, determining whether each node on the target multicast path is an abnormal node;

[0064] S104: If at least one node on the target multicast path is an abnormal node, remove at least one node, replan the target multicast path, and update the target multicast path to the replanned target multicast path.

[0065] As an example, after the network device parses the target multicast path from the target multicast data, it determines whether each node on the target multicast path is an abnormal node. If at least one node on the target multicast path is an abnormal node, it is considered that these nodes cannot forward or receive the target multicast data normally, and cannot transmit the target multicast data according to the target multicast path. At this time, these nodes are eliminated, and the target multicast path is replanned according to the network topology structure where the network device and each receiving terminal are located, as well as the nodes on the target multicast path other than these nodes, and the target multicast path is updated to the replanned target multicast path; if no node on the target multicast path is an abnormal node, it is considered that each node on the target multicast path can forward or receive the target multicast data normally, and supports the transmission of the target multicast data according to the target multicast path. At this time, there is no need to replan the target multicast path.

[0066] In the embodiment of the present application, when it is determined that at least one node on the target multicast path is an abnormal node, at least one node is removed, the target multicast path is replanned, and the target multicast path is updated to the replanned target multicast path. When at least one node on the target multicast path is abnormal, the target multicast path can be replanned to ensure that the target multicast data is successfully transmitted according to the target multicast path, which is conducive to further improving the efficiency of multicast data transmission.

[0067] In an optional embodiment, determining whether each node on the target multicast path is an abnormal node includes: determining the network connection status of each node on the target multicast path; and determining that the node is an abnormal node when the node is offline.

[0068] As an example, after the network device parses the target multicast path from the target multicast data, it determines the network connection status of each node on the target multicast path, such as offline status or online status. When the node is in an offline status, the node is determined to be an abnormal node, and it is considered that the node cannot forward or receive the target multicast data normally due to the disconnection of the network connection; when the node is in an online status, the node is determined to be a normal node, and it is considered that the node still maintains the network connection and can forward or receive the target multicast data normally.

[0069] In actual applications, a detection cycle can be pre-set according to actual application requirements. After the detection cycle arrives, the network device detects the network connection status of each node on the target multicast path, thereby determining the network connection status of each node on the target multicast path.

[0070] The embodiment of the present application determines that each node on the target multicast path is an abnormal node when the network connection status of the node is determined to be offline, and can accurately judge whether the node is an abnormal node according to the network connection status of the node.

[0071] In an optional embodiment, the method further includes step S105:

[0072] S105: Adjust the target multicast path according to the data transmission performance index fed back by each receiving node on the target multicast path, and update the target multicast path to the adjusted target multicast path.

[0073] As an example, after completing the transmission of the target multicast data, the network device waits to obtain the data transmission performance indicator fed back by each receiving node on the target multicast path.

[0074] In an optional implementation manner of this embodiment, the data transmission performance indicator includes one or more of a data transmission delay and a data packet loss rate.

[0075] As an example, after receiving the target multicast data, each receiving node on the target multicast path evaluates the data transmission performance index of this multicast, such as data transmission delay and data packet loss rate, and sends the data transmission performance index of this multicast to the network device.

[0076] After obtaining the data transmission index fed back by each receiving node on the target multicast path, the network device adjusts the target multicast path according to the data transmission performance index fed back by each receiving node on the target multicast path, and updates the target multicast path to the adjusted target multicast path.

[0077] In another optional implementation of this embodiment, when the value of the data transmission performance indicator fed back by any receiving node on the target multicast path is within a preset value range, the target multicast path is adjusted and the target multicast path is updated to the adjusted target multicast path.

[0078] As an example, according to actual application requirements, a value range of the data transmission performance indicator is preset, that is, a preset value range. The network device compares the data transmission performance indicator fed back by each receiving node on the target multicast path with the preset value range, and when the value of the data transmission performance indicator fed back by any receiving node on the target multicast path is within the preset value range, the target multicast path is adjusted, and the target multicast path is updated to the adjusted target multicast path.

[0079] For example, assuming that the data transmission delay fed back by any receiving node on the target multicast path is greater than a preset delay threshold, the node with the largest data transmission delay is selected from all nodes located before the receiving node on the target multicast path as the target node, the target node is eliminated, and the target multicast path is adjusted according to the network topology structure where the network equipment and each receiving terminal are located, and the nodes other than the target node on the target multicast path, and the target multicast path is updated to the adjusted target multicast path.

[0080] It can be understood that the data transmission delay fed back by each receiving node on the target multicast path is determined based on the data transmission delay of each node between the network device and the receiving node, and is the overall data transmission delay.

[0081] The embodiment of the present application adjusts the target multicast path according to the data transmission performance index fed back by each receiving node on the target multicast path, and updates the target multicast path to the adjusted target multicast path, so as to evaluate the data transmission performance index of the current multicast to optimize and adjust the target multicast path, and ensure that the next target multicast data can be transmitted according to the adjusted target multicast path when multicast is performed for each receiving terminal next time, thereby facilitating improving the efficiency of multicast data transmission.

[0082] Please see Figure 2 , Figure 2 A structural diagram of a multicast data transmission device provided for the second embodiment of the present application. The second embodiment of the present application provides a multicast data transmission device, including: a data acquisition module 201, used to acquire target multicast data; wherein the SRv6 segment routing list carried by the target multicast data is embedded with identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path; a data transmission module 202, used to traverse each node on the target multicast path, and when the current node is a forwarding node, control the forwarding node to forward the target multicast data according to the routing path corresponding to the identification information of the forwarding node, and when the current node is a receiving node, control the receiving node to receive the target multicast data.

[0083] In an optional embodiment, the data acquisition module 201 is further used to plan a multicast path from a source node to each receiving node according to a network topology structure before acquiring the target multicast data, so as to obtain a target multicast path.

[0084] In an optional embodiment, the device also includes: a path optimization module, which is used to: determine whether each node on the target multicast path is an abnormal node; if at least one node on the target multicast path is an abnormal node, remove at least one node, and re-plan the target multicast path, and update the target multicast path to the re-planned target multicast path.

[0085] In an optional embodiment, determining whether each node on the target multicast path is an abnormal node includes: determining the network connection status of each node on the target multicast path; and determining that the node is an abnormal node when the node is offline.

[0086] In an optional embodiment, the device further includes: a path optimization module, configured to adjust the target multicast path according to data transmission performance indicators fed back by each receiving node on the target multicast path, and update the target multicast path to an adjusted target multicast path.

The third embodiment of the present application provides a multicast data transmission system, including a network device 301; the network device 301 is used to: obtain target multicast data; wherein the SRv6 segment routing list carried by the target multicast data is embedded with identification information of each node on the target multicast path, and a segment routing path in the SRv6 segment routing list corresponds to the identification information of a node on the target multicast path; traverse each node on the target multicast path, and when the current node is a forwarding node, control the forwarding node to forward the target multicast data according to the routing path corresponding to the identification information of the forwarding node, and when the current node is a receiving node, control the receiving node to receive the target multicast data.

[0090] As an exemplary example, when multiple receiving terminals are in multiple different networks, a service server corresponding to a source node in a target multicast path may be selected as a network device.

[0091] When multiple receiving terminals are in the same network, a local area network forwarding device may be selected as the network device, wherein the local area network forwarding device includes a router or a firewall.

[0092] For example, Figure 4 As shown, assuming that the multiple receiving terminals are A1, A2, A3, B1, B2 and B3, and the multiple receiving terminals are in multiple different networks, the service server corresponding to the source node in the target multicast path is selected as the network device.
