Abstract

Anycast paradigm has been widely adopted by Internet application to find nearby resources. The current IP anycast implementation suffers from poor scalability. To overcome that, this paper proposes Proxima, a network coordinates (NC) based application layer infrastructure, which is capable to provide lightweight and flexible anycast service. Proxima accurately chooses the best receiver from a group of candidates according to the Round Trip Time (RTT) for certain application. Our experimental results have demonstrated the excellent performance of Proxima in real sever selection scenario.
