Abstract
The invention proposes method and apparatus in a plurality of rendezvous points for together processing multicast traffics from mobile multicast source. Wherein, a first rendezvous point and at least one second rendezvous point compose an anycast group which is used for sharing the processing task of the multicast data packets of the mobile multicast source point together, the first rendezvous point and the at least one second rendezvous point share a route forwarding table, the route forwarding table comprises corresponding relation among the care-of-address, the home address and the multicast address of one or more multicast sources. The first rendezvous point obtains the multicast data packets, forwards the multicast data packets to the at least one second rendezvous point, when needing to forward the multicast data packets to the at least one second rendezvous point; the first rendezvous point searches the route forwarding table, according to address information of the multicast packet; determines the corresponding shared multicast tree, when the address information matches the care-of address and/or home address and matches the multicast address of an candidate multicast source; and forwards the multicast data packet according to the shared multicast tree.
