Description

Technical Field

[0001] The embodiments of the present invention relate to the field of network communication technology, and in particular to a grouping method, apparatus, device and storage medium. Background Technology

[0002] Figure 1 This is a schematic diagram of a dual-redundant network topology in existing technology. For example... Figure 1 As shown, a dual-redundant network topology includes 10 switches (SW1 to SW10) and one network management server (IP address 192.168.1.233). Switch SW1 is connected to the network management server, and the 10 switches form a large redundant loop using the DT-RING protocol. Each switch's four ports are divided into two aggregated port-channel 1 and port-channel 2. Between two switches, aggregated port 1 of one switch is connected to aggregated port 2 of the other, forming a small loop. Figure 1 In this context, PtCh1 represents port-channel1. Figure 1 In this context, PtCh2 represents port-channel 2. All switches from SW1 to SW10 are configured with 10 network segments from VLAN 1 to VLAN 10, with IP addresses planned as 192.168.1.1 / 24-192.168.10.10 / 24. Among them, SW1 and SW10 are configured with Layer 3 multicast pim-sm, and all other switches are configured with Layer 2 multicast snooping. SW1 is configured with primary DT-RING, and the other switches are configured with backup DT-RING.

[0003] When any single switch or link in a dual-redundant network topology fails, the DT-RING protocol can quickly detect the fault information and re-determine the multicast source, thereby restoring normal network communication. In existing technologies, when an abnormal link exists, each switch does not know which device is the specific multicast source, requiring a re-election of the multicast source. After determining the multicast source, the multicast information transmission path is then re-determined, resulting in wasted time. For example, in the dual-redundant network topology mentioned above, since Layer 3 multicast PIM-SM is only configured on SW1 and SW10, when an abnormal link exists, SW1 and SW10 will re-elect the multicast source. Only after the multicast source election is complete can an available broadcast path be determined, leading to a longer multicast group joining time. Summary of the Invention

[0039] Example 1

[0040] Figure 2 This is a flowchart of a group-adding method according to an embodiment of the present invention. This embodiment is applicable to group-adding situations. The method can be executed by the group-adding device in this embodiment of the present invention. The device can be implemented in software and / or hardware, such as... Figure 2 As shown, the method specifically includes the following steps:

[0041] S101. Send a broadcast message to the adjacent device so that the adjacent device, after receiving the broadcast message, will send the broadcast message to other devices in the redundant loop.

[0042] The technical solution of this invention is applied to redundant loops. The redundant loop can be a loop formed by all switching devices in a dual-redundant network topology, for example... Figure 1 The redundant loop consists of SW1 to SW10. It includes a multicast source and at least three devices. It should be noted that the multicast source can be the switch device configured as the primary DT-RING in the redundant loop, for example... Figure 1 In SW1, the multicast source is configured with Layer 3 multicast PIM-SM, and at least one device in the redundant loop is configured with Layer 3 multicast PIM-SM, for example... Figure 1 SW10 in the list is a device that can be used to replace the original multicast source when the original multicast source fails to function properly. It should be noted that the devices in the redundant loop can be switching devices, and the other devices besides the multicast source are configured with Layer 2 multicast snooping, for example... Figure 1 SW1 can be configured for Layer 3 multicast, while SW2 through SW10 can be configured for Layer 2 multicast. SW10 can also be configured for Layer 3 multicast. The group joining method is executed by the multicast source.

[0043] It should be noted that adjacent devices can be switch devices adjacent to the multicast source in a redundant loop. For example, such as... Figure 1In the redundant loop shown, if SW1 is the multicast source, then the adjacent devices of the multicast source can be SW2 and SW10.

[0044] The broadcast information can be information emitted by a multicast source. The broadcast information includes the VLAN information of the multicast source.

[0045] Specifically, the multicast source sends broadcast information to devices adjacent to it in the redundant loop. Upon receiving the broadcast information, each adjacent device forwards it to other devices adjacent to it, until all devices in the redundant loop have received the broadcast information. The broadcast information includes the multicast source's VLAN information; that is, once all devices in the redundant loop receive the broadcast information, they can clearly identify which device is the multicast source in the loop. For example, such as... Figure 1 In the redundant loop shown, SW1 is the multicast source. The adjacent devices of the multicast source can be SW2 and SW10. SW1 sends broadcast information to SW2 and SW10. After receiving the broadcast information, SW2 and SW10 send the broadcast information to SW3 and SW9, and so on, until every device in the redundant loop receives the broadcast information and SW1 is identified as the multicast source in this redundant loop.

[0046] S102. Receive the group joining request sent by the target device based on the VLAN information of the multicast source, and generate multicast information based on the group joining request.

[0047] It should be noted that the target device can be a switch device in a redundant loop that is to be added to the multicast group.

[0048] Among them, a group joining request can be a request issued by the target device to join a multicast group.

[0049] In this embodiment, the multicast information may be information about the multicast group generated by the multicast source based on the group joining request sent by the target device. For example, the multicast information may include multicast group address information, etc.

[0050] Specifically, the multicast source receives a group join request sent by the target device based on the multicast source's VLAN information, and generates multicast information based on the group join request sent by the target device.

[0051] S103. Send the multicast information to the target device so that the target device can perform a group joining operation based on the multicast information.

[0052] Specifically, the multicast source sends multicast information to the target device, enabling the target device to join the multicast group based on the multicast information.

[0053] This invention, through its embodiments, sends broadcast information to neighboring devices. Upon receiving the broadcast information, these neighboring devices then forward it to other devices in the redundant loop. The broadcast information includes: VLAN information of the multicast source; a group joining request sent by the target device based on the VLAN information of the multicast source; multicast information generated based on the request; and the multicast information sent to the target device, enabling the target device to perform a group joining operation based on the multicast information. By using this invention's technical solution, the multicast source sends broadcast information including its VLAN information to all devices in the redundant loop before joining a group. This allows all devices in the redundant loop to clearly identify which device is the multicast source, eliminating the multicast source election time required in existing technologies. Furthermore, it reduces multicast regrouping time and improves group joining efficiency when re-determining the multicast source in a dual-redundant network topology.

[0054] Optionally, multicast information is sent to the target device so that the target device can join the group based on the multicast information, including:

[0055] The multicast routing table is queried based on the identification information of the target device carried in the group joining request to obtain the multicast information sending path.

[0056] For example, the identification information of the target device may be the name of the target device and / or the IP address of the target device, or other identifying information.

[0057] In this embodiment, the multicast routing table can be a table that records the interaction methods between each switch device in the redundant loop, as well as the path for sending messages between each switch device in the redundant loop. In actual operation, each switch device in the redundant loop stores a multicast routing table. For example, the records in the multicast routing table may include: SW1 and SW2 interact via VLAN1, SW2 and SW3 interact via VLAN2, SW3 and SW4 interact via VLAN3, ..., SW9 and SW10 interact via VLAN9, SW10 and SW1 interact via VLAN10, each device uses a different network connection, and the path for sending messages between each switch device in the redundant loop may be, for example, SW1→SW2→SW3→SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1, etc.

[0058] Among them, the multicast information sending path can be the path through which the multicast source sends multicast information to the target device.

[0059] Specifically, the multicast source queries the multicast routing table based on the target device identification information carried in the received group join request to obtain the multicast information transmission path. For example, such as... Figure 1In the redundant loop shown, SW1 acts as the multicast source, and the target device is SW4. The identification information of the target device can be SW4 and / or SW4's IP address. After receiving the group join request from the target device SW4, the multicast source queries the multicast routing table based on the identification information of the target device SW4. The resulting multicast information transmission path can be SW1→SW2→SW3→SW4, or it can be SW1→SW10→SW9→SW8→SW7→SW6→SW5→SW4.

[0060] Multicast information is sent to the target device according to the multicast information sending path, so that the target device can perform a group joining operation based on the multicast information.

[0061] Specifically, the multicast source sends multicast information to the target device according to the multicast information transmission path, so that the target device can join the multicast group based on the multicast information. For example, multicast source SW1 sends multicast information to neighboring device SW2, SW2 sends multicast information to device SW3, SW3 sends multicast information to target device SW4, and target device SW4 joins the group based on the multicast information.

[0062] Optionally, the multicast routing table can be queried based on the target device's identification information to obtain the multicast information transmission path, including:

[0063] If an abnormal link is detected in the redundant loop, the multicast routing table is updated. The updated multicast routing table is queried based on the identification information of the target device to obtain the multicast information sending path with normal link status.

[0064] In this embodiment, the abnormal link can be a link in a redundant loop that is malfunctioning. Preferably, the abnormal link can be, for example, a blocked link. Figure 3 This is a schematic diagram of a dual-redundant network topology where there is a blocking link between SW1 and SW10, as shown below. Figure 3 As shown, the port-channel 1 connecting SW1's port-channel 2 and SW10 could be a blocking link, meaning that SW1 and SW10 cannot exchange information and cannot communicate; for example... Figure 4 This is a schematic diagram of a dual-redundant network topology where there is a blocking link between SW1 and SW2, as shown below. Figure 4 As shown, the port-channel 2 connecting SW1 and SW2 may be a blocked link, meaning that SW1 and SW2 cannot transmit information and cannot communicate.

[0065] Specifically, if the multicast source detects an abnormal link in the redundant loop, it updates the multicast routing table based on the connection status of each switch device in the redundant loop, resulting in an updated multicast routing table. For example... Figure 4 The abnormal link shown can be updated to SW1→SW10→SW9→SW8→SW7→SW6→SW5→SW4→SW3→SW2, and this link is now in a normal state. The multicast source queries the updated multicast routing table based on the target device identification information carried in the received group join request to obtain the multicast information transmission path with a normal link status.

[0066] Optionally, multicast information is sent to the target device so that the target device can join the group based on the multicast information, including:

[0067] Determine the path for sending the group addition request to the target device.

[0068] It should be noted that the path for sending a group join request can be the path taken by the target device when sending the group join request to the multicast source.

[0069] Specifically, determine the group join request sending path when the target device sends a group join request to the multicast source. For example, such as... Figure 1 In the redundant loop shown, SW1 is the multicast source and the target device is SW4. When the target device SW4 sends a group join request to the multicast source SW1, the group join request sending path can be SW4→SW3→SW2→SW1, and the group join request sending path can also be SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1.

[0070] The multicast information sending path is determined based on the group joining request sending path.

[0071] Specifically, the reverse process of the group join request sending path can be directly determined as the multicast information sending path. That is, if the group join request sending path is SW4→SW3→SW2→SW1, then the multicast information sending path can be SW1→SW2→SW3→SW4.

[0072] Multicast information is sent to the target device according to the multicast information sending path, so that the target device can perform a group joining operation based on the multicast information.

[0073] Specifically, the multicast source sends the multicast information to the target device according to the multicast information sending path, so that the target device can join the multicast group based on the multicast information.

[0074] Optionally, determine the group joining request sending path for the target device, including:

[0075] If an abnormal link is detected in the redundant loop, the transmission path that does not contain the abnormal link is determined as the path for sending the group addition request.

[0076] For example, such as Figure 1In the redundant loop shown, SW1 acts as the multicast source, and the target device is SW4. The identification information of the target device can be SW4 and / or SW4's IP address. After receiving the group join request from the target device SW4, if the multicast source detects an abnormal link in the redundant loop, such as an abnormal link between SW1 and SW10, it can determine the transmission path SW4→SW3→SW2→SW1, which does not contain the abnormal link, as the group join request sending path.

[0077] The multicast information transmission path is determined based on the group join request transmission path, including:

[0078] Use the reverse process of the group request sending path as the multicast information sending path.

[0079] For example, the reverse process of the group join request sending path can be directly determined as the multicast information sending path. That is, when the transmission path SW4→SW3→SW2→SW1 without abnormal links is used as the group join request sending path, the multicast information sending path can be SW1→SW2→SW3→SW4.

[0080] Optionally, determine the group joining request sending path for the target device, including:

[0081] Obtain at least two paths between the target device and the multicast source, determine the shortest path from the at least two paths, and if no abnormal link is detected in the shortest path, use the shortest path as the path to send the group join request.

[0082] For example, such as Figure 1 In the redundant loop shown, SW1 serves as the multicast source, and SW4 is the target device. The paths between the target device and the multicast source can include: SW4→SW3→SW2→SW1 and SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1. It can be seen that SW4→SW3→SW2→SW1 is the shortest path among these two. When no abnormal link is detected in the shortest path SW4→SW3→SW2→SW1, the shortest path SW4→SW3→SW2→SW1 can be directly used as the path for sending group join requests.

[0083] If an abnormal link is detected in the shortest path, then any one or more paths outside the shortest path will be used as the path for sending the group addition request.

[0084] For example, in the above example, if an abnormal link is detected in the shortest path SW4→SW3→SW2→SW1, any one or more paths other than the shortest path can be used as the path for sending the group request. For example, the path SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1 can be used as the path for sending the group request.

[0085] Determining the multicast information transmission path based on the group join request transmission path includes: using the reverse process of the group join request transmission path as the multicast information transmission path.

[0086] For example, if the shortest transmission path SW4→SW3→SW2→SW1 is the group join request sending path, the multicast information sending path can be SW1→SW2→SW3→SW4; if the path SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1 is the group join request sending path, the multicast information sending path can be SW1→SW10→SW9→SW8→SW7→SW6→SW5→SW4.

[0087] The above implementation methods are several ways to determine the multicast information transmission path. By implementing the above implementation methods, it can be ensured that the multicast information can be sent to the target device so that the target device can join the group, avoiding the problem that the multicast information cannot reach the target device due to link abnormalities.

[0088] The technical solution of this invention involves sending broadcast information to neighboring devices, enabling these devices to forward the broadcast information to other devices in a redundant loop upon receipt. The broadcast information includes: VLAN information of the multicast source; a group joining request sent by the target device based on the VLAN information of the multicast source; and multicast information generated based on the group joining request. If an abnormal link is detected in the redundant loop, the multicast routing table is updated. The updated multicast routing table is queried based on the identifier information of the target device to obtain a multicast information transmission path with a normal link status. If an abnormal link is detected in the redundant loop, then... The transmission path without abnormal links is used as the group joining request sending path, and the reverse process of the group joining request sending path is used as the multicast information sending path. At least two paths between the target device and the multicast source are obtained, and the shortest path is determined from these at least two paths. If no abnormal link is detected in the shortest path, the shortest path is used as the group joining request sending path. If an abnormal link is detected in the shortest path, any one or more paths other than the shortest path are used as the group joining request sending path. Multicast information is sent to the target device according to the multicast information sending path, so that the target device can perform a group joining operation based on the multicast information. Through the technical solution of this invention, before joining a group, the multicast source first sends broadcast information including the VLAN information of the multicast source to all devices in the redundant loop. This allows all devices in the redundant loop to clearly identify which device is the multicast source in this redundant loop, saving the time of multicast source election in the prior art. When re-determining the multicast source in a dual-redundant network topology, it reduces the multicast re-joining time and improves joining efficiency.

[0089] Example 2

[0090] Figure 5 This is a flowchart of another grouping method in an embodiment of the present invention. This embodiment is applicable to grouping situations. This method can be executed by the grouping device in the embodiment of the present invention. The device can be implemented in software and / or hardware, such as... Figure 5 As shown, the method specifically includes the following steps:

[0091] S201, Receive broadcast information sent by neighboring devices.

[0092] The broadcast information includes: VLAN information of the multicast source.

[0093] The technical solution of this invention is applied to redundant loops. The redundant loop can be a loop formed by all switching devices in a dual-redundant network topology, for example... Figure 1 The redundant loop consists of SW1 to SW10. It includes a multicast source and at least three devices. It should be noted that the multicast source can be the switch device configured as the primary DT-RING in the redundant loop, for example... Figure 1 In SW1, the multicast source is configured with Layer 3 multicast PIM-SM, and at least one device in the redundant loop is configured with Layer 3 multicast PIM-SM, for example... Figure 1 SW10 in the list is a device that can be used to replace the original multicast source when the original multicast source fails to function properly. It should be noted that the devices in the redundant loop can be switching devices, and the other devices besides the multicast source are configured with Layer 2 multicast snooping, for example... Figure 1 SW1 can be configured for Layer 3 multicast, while SW2 through SW10 can be configured for Layer 2 multicast. SW10 can also be configured for Layer 3 multicast. Joining a multicast group is done by the target device to be added to the multicast.

[0094] Specifically, devices in the redundant loop receive broadcast information sent by neighboring devices. These neighboring devices include multicast sources. The broadcast information includes the VLAN information of the multicast sources.

[0095] In practice, when the target device's neighboring device is a multicast source, the target device directly receives broadcast information sent by the multicast source. For example, such as... Figure 1 In the redundant loop shown, SW1 acts as the multicast source, and SW2 directly receives broadcast information sent by the multicast source SW1. When the target device's neighboring device is not a multicast source, the target device receives broadcast information sent by its neighboring device. The neighboring device then receives broadcast information sent by other devices adjacent to the target device, and so on, until a neighboring device becomes the multicast source. The broadcast information includes the multicast source's VLAN information; that is, once all devices in the redundant loop receive the broadcast information sent by the multicast source, they can clearly identify which device in the redundant loop is the specific multicast source.

[0096] For example, such as Figure 1 In the redundant loop shown, SW1 acts as the multicast source. When device SW4 is selected, the broadcast information received by SW4 can originate from SW3, the broadcast information received by SW3 can originate from SW2, and the broadcast information received by SW2 can originate directly from the multicast source SW1. This continues until every device in the redundant loop receives the broadcast information, thus confirming SW1 as the multicast source in the redundant loop.

[0097] S202. Send the group joining request to the multicast source according to the VLAN information of the multicast source, so that the multicast source can generate multicast information according to the group joining request.

[0098] Specifically, devices in the redundant loop send group join requests to the multicast source based on the multicast source's VLAN information, so that the multicast source generates multicast information based on the group join requests. For example, the process of a target device sending a group join request to the multicast source can be the reverse process of the target device receiving broadcast information; that is, the target device can send the group join request to neighboring devices, which in turn send the group join request to other devices adjacent to the connected device, until the group join request is sent to the multicast source.

[0099] S203. Receive multicast information sent by the multicast source and perform group addition operation according to the multicast information sent by the multicast source.

[0100] Specifically, devices in the redundant loop receive multicast information from the multicast source and join the multicast group based on the multicast information sent by the multicast source.

[0101] This invention, through its embodiments, receives broadcast information sent by neighboring devices. This broadcast information includes the VLAN information of the multicast source. A grouping request is sent to the multicast source based on the VLAN information, causing the multicast source to generate multicast information. The device then receives the multicast information from the multicast source and performs a grouping operation based on it. By using this invention, all devices in the redundant loop receive broadcast information including the VLAN information of the multicast source before grouping. This allows all devices in the redundant loop to clearly identify which device is the multicast source, eliminating the multicast source election time required in existing technologies. Furthermore, it reduces the multicast regrouping time and improves grouping efficiency when re-determining the multicast source in a dual-redundant network topology.

[0102] Optionally, the group join request is sent to the multicast source based on the multicast source's VLAN information, so that the multicast source generates multicast information based on the group join request, including:

[0103] The multicast routing table is queried based on the VLAN information of the multicast source to obtain the path for sending the group joining request.

[0104] Specifically, each switch in the redundant loop stores a multicast routing table. Devices in the redundant loop query the multicast routing table based on the VLAN information of the multicast source to obtain the path for sending the group join request. For example, such as... Figure 1 In the redundant loop shown, SW1 acts as the multicast source. When device SW4 sends a group join request to SW1, it can query the multicast routing table stored in SW4 based on the VLAN information of the multicast source to obtain the group join request sending path. For example, the group join request sending path when device SW4 sends a group join request to multicast source SW1 can be SW4→SW3→SW2→SW1, or it can be SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1.

[0105] The group join request is sent to the multicast source according to the group join request sending path, so that the multicast source can generate multicast information based on the group join request.

[0106] Specifically, the devices in the redundant loop send the group request to the multicast source according to the group request sending path, so that the multicast source can generate multicast information based on the group request.

[0107] Optionally, the group joining request carries the target device's identification information; the multicast information received from the multicast source includes:

[0108] Receive multicast information sent by the multicast source through the multicast information sending path. The multicast information sending path is obtained by the multicast source by querying the multicast routing table based on the identification information.

[0109] Specifically, the device receives multicast information sent by a multicast source through a multicast information transmission path. This multicast information transmission path is obtained by the multicast source by querying the multicast routing table based on its identification information. For example, such as... Figure 1 In the redundant loop shown, SW1 acts as the multicast source, and SW4 is the target device. The target device's identification information can be SW4 and / or its IP address. After receiving a group join request from the target device SW4, the multicast source queries the multicast routing table based on SW4's identification information. The resulting multicast information transmission path can be either SW1→SW2→SW3→SW4 or SW1→SW10→SW9→SW8→SW7→SW6→SW5→SW4. The multicast source sends the multicast information to the target device through this path, and the target device receives the multicast information sent by the multicast source through the same path.

[0110] Optionally, the multicast information received from the multicast source includes:

[0111] Receive multicast information sent by the multicast source through the multicast information sending path. The multicast information sending path is obtained by the multicast source in reverse process of the target device's group joining request sending path.

[0112] Specifically, the target device receives multicast information sent by the multicast source through a multicast information transmission path. This multicast information transmission path is obtained by the multicast source through the reverse process of the target device's group join request transmission path. For example, such as... Figure 1 In the redundant loop shown, SW1 acts as the multicast source, and SW4 is the target device. The identification information of the target device can be SW4 and / or its IP address. The group join request sending path for the target device SW4 could be, for example, SW4→SW3→SW2→SW1. The reverse process of the group join request sending path for the target device SW4 is SW1→SW2→SW3→SW4. The multicast information sending path for the multicast source SW1 can be SW1→SW2→SW3→SW4. The device receives the multicast information sent by the multicast source through the multicast information sending path SW1→SW2→SW3→SW4.

[0113] Optionally, the group request can be sent via the shortest path obtained after querying the multicast routing table.

[0114] Specifically, when the target device sends a group join request to the multicast source, it can first query the multicast routing table to obtain the shortest path among the paths from the device to the multicast source, and then send the group join request to the multicast source through the shortest path. For example, such as... Figure 1 In the redundant loop shown, SW1 acts as the multicast source, and the target device is SW4. The identification information of the target device can be SW4 and / or SW4's IP address. After querying the multicast routing table, it is found that there are two paths for the target device SW4 to send a group join request to the multicast source SW1: SW4→SW3→SW2→SW1 and SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1. It can be seen that SW4→SW3→SW2→SW1 is the shortest of the two paths. Therefore, SW4→SW3→SW2→SW1 can be the path for the target device SW4 to send the group join request to the multicast source SW1.

[0115] Optionally, before querying the multicast routing table based on the VLAN information of the multicast source to obtain the path for sending the group join request, the following steps are also included:

[0116] A multicast routing table is generated based on the link status of redundant loops.

[0117] It should be noted that the link status of a redundant loop can be the link status when all the switching devices in the redundant loop form a loop. For example, the link status of a redundant loop can include: a normal state and a state where there are abnormal links in the redundant loop.

[0118] In this embodiment, the multicast routing table can be a table that records the interaction methods between each switch device in the redundant loop, as well as the path for sending messages between each switch device in the redundant loop. In actual operation, each switch device in the redundant loop stores a multicast routing table. For example, the records in the multicast routing table may include: SW1 and SW2 interact via VLAN 1, SW2 and SW3 interact via VLAN 2, SW3 and SW4 interact via VLAN 3, ..., SW9 and SW10 interact via VLAN 9, SW10 and SW1 interact via VLAN 10, each device uses a different network connection, and when the link status of the redundant loop is normal, the path for sending messages between each switch device in the redundant loop could be, for example, SW1→SW2→SW3→SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1, etc.

[0119] Specifically, devices in the redundant loop generate multicast routing tables based on the link status of the redundant loop and save the generated multicast routing tables.

[0120] If an abnormal link is detected in the redundant loop, the multicast routing table is updated according to the abnormal link.

[0121] Specifically, devices in the redundant loop can monitor the link status of the redundant loop in real time. When an abnormal link is detected in the redundant loop, the multicast routing table is updated according to the abnormal link. For example, when the link status of the redundant loop was normal, the path for sending messages between each switch device in the redundant loop stored in the generated multicast routing table could be SW1→SW2→SW3→SW4→SW5→SW6→SW7→SW8→SW9→SW10→SW1. When an abnormal link is detected, for example, between SW1 and SW2, the multicast routing table updated according to the abnormal link could be SW1→SW10→SW9→SW8→SW7→SW6→SW5→SW4→SW3→SW2.

[0122] The technical solution of this invention involves receiving broadcast information sent by neighboring devices. The broadcast information includes: VLAN information of the multicast source; generating a multicast routing table based on the link status of the redundant loop; updating the multicast routing table based on the abnormal link if an abnormal link is detected in the redundant loop; querying the multicast routing table based on the VLAN information of the multicast source to obtain the group joining request sending path; sending the group joining request to the multicast source according to the group joining request sending path, so that the multicast source generates multicast information based on the group joining request. The group joining request carries the identification information of the target device. The system also receives multicast information sent by the multicast source through the multicast information sending path, which is obtained by the multicast source querying the multicast routing table based on the identification information; and performs a group joining operation based on the multicast information sent by the multicast source through the multicast information sending path, which is obtained by the multicast source through the reverse process of the target device's group joining request sending path. The technical solution of this invention allows all devices in the redundant loop to receive broadcast information including the VLAN information of the multicast source before grouping. This enables all devices in the redundant loop to clearly identify which device is the multicast source in the redundant loop, saving the time of multicast source election in the prior art. When re-determining the multicast source in a dual-redundant network topology, it reduces the multicast regrouping time and improves grouping efficiency.
