Exploiting well resources of end hosts to extend the service scalability of a media server is a critical approach in multimedia streaming services. This paper proposes a peer-to-peer network coding based streaming system (PNECOS) to provide overlay multimedia(More)
Many existing studies in overlay networking have focused on resource discovery or server selection. This work studies the integrated performance of peer-to-peer (P2P) file sharing systems using location-aware resource discovery and service scheduling schemes. A novel file capacity amplification (FCA) model is first presented to capture the problem of the(More)

Service-oriented networks often require in-transit services or processing for application packets. Thus, besides bandwidth requirement, applications or services must also specify their computing power need. Current QoS specification models, however,(More)
