Demand on Request and Performance Evaluation in Video MAC Protocol (VMP) for EPON based Network

Abstract

MAC Protocol (VMP) in EPON based access networks. In triple-play (Data, Voice, and Video) service scenarios for such EPON based access networks, Optical network technologies are expected to converge in the near future, since the fiber networks hold great promise as future broadband communication. Video traffic will likely dominate in triple-play service scenarios for each fiber networks. It is proposed to introduce and analyze the Video MAC Protocol (VMP) to efficiently deliver pre-recorded video downstream to consumers over a fiber network in presence of voice and data upstream and downstream traffic. The VMP consists of three main components: (i) Frame Fragmentation and Hierarchical frame Aggregation, (ii) Multi-Polling Channel Access, and (iii) Prefetching for VBR Video Streams. By introducing VMP we are going to analyze the throughput- delay performance for all three traffic types: Voice Traffic, Video Traffic, and Data Traffic. In this paper we are evaluating a demand on request and performance evaluation of VMP. Video streaming according to the user requirement and encoded in three quality types of Video for low, medium and high quality users and the most common performance metrics are delay and throughput are compared with existing Mac protocol.
