摘要

With the rapidly development of broadband networks, more and more users nowadays tend to acquire their desired videos from media-on-demand servers. How to efficiently provide multimedia contents for a large number of heterogeneous users on the Internet has become a noticeable issue. In our previous work, we proposed the Loopback-MDC scheme on CDN-P2P network to address such a scalability issue. In this paper, we present the design and implementation of a novel peer-to-peer streaming system with the Loopback-MDC on actual networks, named TuBeck. The TuBeck consists of preprocessor, server, peer, and player modules with the support of network infrastructure library. In TuBeck, multimedia sources are preprocessed to multiple descriptions. Each description is divided as a sequence of H.264/AVC chunks by modified JM encoder for real-time streaming. The network infrastructure library provides the nodes (server and peers) with the fundamental functionalities of network connections and communications. Message exchange and streaming control among nodes follow the pre-defined LM protocol. The server, peer, and player modules are functionally multithreaded in order to enhance the system performance. The experimental results show that the Loopback-MDC is practical for realizing a P2P streaming system in terms of the server loading, CPU/Memory usage, and efficiency of failure recovery with respect to various arrival rates, failure rates, and viewing qualities.
