QoS Provisioning for Video Streaming over SP-Driven P2P Networks Using Admission Control

In this paper, we present an admission control mechanism for video streaming driven by service provider (SP) over P2P networks. SP-driven P2P network is a network in which service provider has a comprehensive control over contracted resources utilisation. SP assures the coordination and the creation of overlay P2P network and it is responsible for admission control and resource allocation among others. Our proposed quality-of-service (QoS) provisioning mechanism employs video traffic descriptor (i.e. traffic specification) for performing admission control. The proposed mechanism is evaluated using ns2 simulator and the results show the significance of admission control mechanism for QoS provisioning.
