Method and apparatus for tunneling service of explicit multicast in mobile IP network |
摘要 |
Inventive embodiments relate to a method and an apparatus for tunneling service of an explicit multicast in a mobile IP network to forward multicast packets to plural mobile nodes with effect. When the apparatus providing the tunneling service for an explicit multicast in a mobile IP network receives a multicast packet from a correspondent node with a network, it extracts mobile nodes existing in a path for tunneling from among the plurality of mobile nodes. Also, after it creates an explicit multicast tunnel header having a destination address as a Co-Located Care-of Address (CL COA) of the mobile nodes existing in the path for tunneling, it tunnels a multicast packet that was encapsulated using the explicit multicast tunnel header to the mobile nodes.
