Collaborative Proxy Peering System (CPPS) for scalable video streaming

Single proxy is not enough to serve thousands of clients in a proxy based scalable streaming scheme. This is because the performance bottleneck shifts from the server to the proxy. Multiple proxies can be deployed in the above scheme to overcome the problem. If these proxies remain isolated, i.e., non-collaborative, overall resource utilization at these proxies will be very poor. We propose that these proxies that serve a particular video in a proxy based scalable streaming scheme should form a collaborative proxy peering system (CPPS). Simulation result shows that our proposed CPPS reduces server-proxy bandwidth requirement and the proxy buffer requirement compared to non-collaborative proxy deployment.
