Implementing multicast on id/locator separation network

Multicasting is a way to deliver copies of single message to multiple recipients at different locations. On the traditional internet, group members join specific multicast address through membership management protocol and packets are delivered along the path tree built by multicast routing protocol. Now we consider how multicast-style communication can be designed in id/locator separation environment. In this environment a common id as a group name can be used and it is shared by all group members, or a specific id can be assigned to an anchor point and packets are distributed to the group members by the anchor point. Mixture of both mechanisms is also possible. In this paper we redefine groupcasting instead of traditional multicasting, and show how multicasting can be designed and implemented in id/locator separation network environment.
