Multimedia Proxy Caching Mechanism for Quality Adaptive Streaming Applications in the Internet
The Internet has witnessed a rapid growth in deployment of Web-based streaming applications during recent years. In these applications, server should be able to perform end-to-end congestion control and quality adaptation to match the delivered stream quality to the average bandwidth available. The delivered quality is limited by the bottleneck bandwidth on the path to the client. This paper proposes a proxy caching mechanism for layered-encoded multimedia streams in the Internet to maximize the delivered quality of popular streams to interested clients.
