Embodiment 1

[0062] The embodiment of the present invention provides a multicast service fault handling method, which can be used for routers adopting the design mode of the master management board, and can also be used for routers adopting the design mode of the master-slave management board. like figure 2 As shown, the method includes:

[0063] Step 201, the main management board determines whether to perform graceful restart.

[0064] Wherein, the main management board is the main management board of the E-BSR, and the PIM-SM protocol runs on the main management board of the E-BSR. Then, the main management board of the E-BSR determines whether to perform a graceful restart, which is the E-BSR The master management board determines whether the PIM-SM protocol it runs needs to be gracefully restarted. Specifically, it can be judged according to the actual operation status of the PIM-SM protocol running on the main management board of the E-BSR. If the PIM-SM protocol running on the m...

Embodiment 2

[0077] The embodiment of the present invention provides a multicast service fault handling method, which is applied to a router adopting a redundant design mode of dual management boards, and the dual management boards include a master management board and a slave management board. like Figure 4 As shown, when the PIM-SM protocol running on the main management board of the E-BSR determines that a graceful restart is required, steps 401-405 can be performed, wherein, steps 401-405 are the same as steps 201-205 in the first embodiment Similarly, details can be referred to the description in Embodiment 1, which will not be repeated here; further, the main management board also executes steps 406-407 while performing graceful restart. specific,

[0078] Step 401, the main management board determines whether to perform graceful restart.

[0079] Step 402, if it is determined to perform a graceful restart, construct a message according to the pre-stored first data information, th...

Embodiment 3

[0096] The embodiment of the present invention provides a multicast service fault handling method, and the method is applied to an E-BSR router adopting a redundant design mode of dual management boards, and the dual management boards include a master management board and a slave management board. When the master management board fails and cannot be gracefully restarted, the slave management board replaces the master management board to handle the fault. Therefore, the subject of execution of this method is the slave management board of the E-BSR. Specifically, such as Figure 5 As shown, the method includes:

[0097] Step 501: Construct a message according to pre-stored data information, the pre-stored data information includes C-BSR data information, C-RP data information and PIM Hello message data information.

[0098] Wherein, the pre-stored data information is sent from the master management board to the slave management board, and the data information sent by the master...

Abstract

An embodiment of the invention provides a fault processing method and device of a multicast service, relates to the technical field of communication, and solves the problem of multicast message forwarding interruption caused by the fact that the PIM-SM protocol operated on an E-BSR fails and the PIM-SM protocol cannot restart gracefully in an appointed time. The method includes: by a main managing board, determining whether to perform graceful restart or not; if so, constructing a message according to pre-stored first data information, wherein the first data information includes the data information of a candidate bootstrap router (C-BSR), the data information of a candidate rendezvous point (C-RP) and the data information of the PIM Hello message; transmitting the message to neighboring equipment, wherein the message includes the BSM message and the PIM Hello message. The method is applicable to data transmission of multicast networks.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for troubleshooting a multicast service. Background technique [0002] Multicast is a point-to-multipoint IP transmission technology. Its basic idea is: when a multicast source sends a multicast packet to a certain multicast group, it only needs to send a multicast packet to make the multicast All network nodes in the multicast group receive the same multicast message. This characteristic of multicast can effectively save network bandwidth and reduce network load. Currently, Protocol Independent Multicast-Sparse Mode (PIM-SM for short) has become one of the most widely used routing protocols in multicast networks due to its good scalability. like figure 1 Shown is the basic architecture diagram of the PIM-SM multicast network. Among them, router A is the designated router (Designated Router, DR for short) at the source end, router B is the re...
