Abstract:

Based on the research of multiparty-communication and IP multicast, a new IPv6 addressing method is proposed to support multiparty-communication applications with small-scale group. This algorithm utilizes the extension header of IPv6, an extension header called destination address extension header is designed. The new method is between unicast and multicast, which is similar to multicast on the performance and similar to unicast on the route. This method avoids the deficiency of the unicast and the multicast on the multiparty-communication with small-scale group. The new addressing method can support many multiparty-communication applications very well, but change the current protocol little.

Key words: multiparty-communication, addressing, multicast, unicast
