Proxima: Towards Lightweight and Flexible Anycast Service
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.
