摘要：In the tremendous growth of the Internet technologies has come up the Quality of Service (QoS) problems in heterogeneous, distributed real time applications like Video-on-Demand (VoD) system. The most challenging task in VoD applications is to satisfy various peers request for distinct videos with available resources without compromising the quality of video streams by invoking various QoS parameters. Therefore we have proposed a quality of service in chaining mechanism for peer to peer video on demand system. We have also considered the transmission of video streams among the peers and then compared with our proposed mechanism with some of the existing techniques such as standard, advanced, optimal and accelerated chaining mechanisms. To our proposed VoD architecture we have proposed the quality of service parameters like delay, jitter calculation between the peers. In our Video Chaining (V-Chaining) mechanism improves the performance of the chaining mechanism in terms of quality of service for video streaming and also maintains minimal jitter in the VoD system. Hence we have evaluated this through the simulation for different performance metrics such as average number of requests arrivals, served and rejected in the system, which is compared with the existing mechanism. The results of the simulation show our proposed V Chaining mechanism enhances the quality of video streaming than the existing mechanisms.
