Collaborative Multi-Source Scheme for Multimedia Content Distribution

Abstract

Demand for multimedia contents has increased in recent years, and several distribution services have emerged. Many of these multimedia distribution services are based on central servers, which introduce several limitations related with costs, dependence, performance or scalability. This paper presents a collaborative scheme for multimedia content distribution. Collaborative infrastructures for multimedia services are critical because multimedia contents have an import consume of resources in the communication networks. P2P networks have emerged as promising solution to implement collaborative infrastructures. Multi-source schemes are a practical solution when different parts of multimedia content is generated or stored in two or more sites. We have used a P2P network to implement a practical distribution prototype of our collaborative multi-source scheme. Our evaluation shows as peers share storage capacity, contents and bandwidth capacity, while server is released from this workload.
