Design, implementation and evaluation of routing protocols for IPv6 anycast communication

Anycast is a new IPv6 feature that supports service-oriented address assignments in IPv6 networks. Because there are no protocol standards or even consensus on routing protocols, intersegment anycast communications are not yet available. In this paper, we propose two routing protocols for intersegment anycast to support anycast-oriented communication. Our proposed architecture (1) achieves the advantages of anycast communications, (2) takes the deployment scenario into the existing unicast network into consideration, and (3) maintains scalability. We also implement the proposed routing protocols in an experimental environment and verify that they work correctly.
