Communication Architecture for Providing Stable Streaming Services by Anycasting

摘要

Streaming services are aimed at distributing multimedia data in real-time, and a server providing streaming services requires high processing power and reliability. In this paper, we propose a new, low-cost, and easily implemented scheme which establishes a fault-tolerant streaming service by using a clustering technique. Our approach is based on anycasting for load balancing in the clustered servers. We have implemented our proposed architecture and have verified that the architecture provides streaming service continuously without any halt in reproduction even if some streaming servers fail while in service. Furthermore, we discuss applying our approach to an existing streaming service, and show that it is easy to implement.
