摘要:
The present invention provides a method and apparatus for multicast tunneling for mobile devices. The method comprises receiving a multicast packet directed to a plurality of mobile nodes, the mobile nodes being associated with a home subnet and identifying if any of the plurality of the mobile nodes are coupled to a subnet other than the home subnet, wherein each of the identified mobile nodes has an associated transmission path through which that mobile node can be reached. The method further provides that in response to determining that at least some of the mobile nodes are coupled to the subnet other than the home subnet, determining which of the identified mobile nodes has a common next hop in their associated transmission path and generating a packet including at least a portion of the multicast packet and including in the packet a list of mobile nodes that have the common next hop. The method further provides for transmitting the generated packet to the common next hop.
