DESIGN AND IMPLEMENTATION OF A MULTIMEDIA PERSONALIZED SERVICE OVER LARGE SCALE NETWORKS

摘要

In this paper, we proposed to setup a distributed multimedia system which aggregates the capacity of multiple servers to provide customized multimedia services in a cost-effective way. Such a system enables clients to customize their services by specifying the service delay or the viewing times. We developed an experimental prototype in which media servers can cooperate in streams caching, replication and distribution. We applied a variety of stream distribution algorithms to the system and studied their performance under the real-life situations with limited network resources and varying request arrival pattern. The results show such a system can provide cost-effective services and be applied to practical environments.
