A secure communication model of solving anycast scalability in IPv6

The existing designs for providing anycast services are either to confine each anycast group to a preconfigured topological region or to globally distribute routes to individual anycast group, both of which are all confronted with two problems: scalability and security. A new kind of Anycast communication model is proposed in this paper, which not only solves Anycast existing scalability and security problem but also allows Anycast members to freely leave and join Anycast group. In addition, this model accomplishes the distributed maintenance and transaction of the information on Anycast members so in some sense it fulfills the load balance. This paper deeply analyzes and discusses the feasibility and performance of this communication model, and argues that it is able to support the large-scale Anycast group.
