Abstract:

As the existing IP-Anycast approaches can not simultaneously achieve the scalability and the efficient group member selection, this paper proposes a tunnel-based scalable global IP-Anycast approach named TGIA. TGIA, transparent to both the upper protocol and the applications, transfers the Anycast request on its main path, combines the advantages of Unicast with IP-Tunnel to efficiently select the best group member, and controls the size of routing table by flooding the Anycast server information in a small region. Thus, the scalability of Anycast is implemented to a certain degree. Simulated results have proved the correctness and effectiveness of TGIA in IP- Anycast service.

Key words: Anycast, routing, IP Tunnel, architecture
