METHOD, SYSTEM, AND DEVICE FOR PROTECTING MULTICAST IN COMMUNICATION NETWORK |
摘要 |
The present invention discloses a method, a system, and a device for protecting multicast in a communication network. The technical solution of the present invention is: In a communication multicast network, a main node and a backup node serve as root nodes to generate two multicast trees simultaneously; the multicast tree that uses the backup node as a root node is set to be in a silent state; when the network is faulty, and the current main multicast tree is unable to forward multicast packets to all leaf nodes in the multicast tree, the silent state of the backup multicast tree is canceled and the backup multicast tree starts forwarding the multicast packets.
