最近，它已被证明，网络编码可以大大提高网络吞吐量的通信系统中，特别是增加下载性能的P2P网络。提出了一种新的基于GIA的P2P网络流媒体直播系统。在所提出的系统中，传统的GIA协议进行了改进，以有效地使用在多媒体应用。我们引入了一个新的网格拉分层视频流框架GIA为基础的系统，并采用随机网络编码，以提高网络性能。随机网络编码算法使每个节点向目的节点发送单个编码视频块而不是多个视频块，并在很大程度上节省其下载和上传带宽。与传统的GIA直播系统相比，新的GIA直播系统在端到端总延迟、网络吞吐量和带宽使用冗余方面都有了显著的改善。
Recently it has been shown that network coding can highly improve the network throughput in the communication systems and specifically increase the downloading performance in P2P networks. This paper presents a new live streaming system for GIA-based P2P networks. In the proposed system the traditional GIA protocol is improved for an efficient use in multimedia applications. We introduce a new mesh-pull layered video streaming framework for GIA-based systems and employ random network coding to improve the network performance. Random network coding algorithm enables each peer to send a single encoded video chunk instead of multiple video blocks toward the destination node and save its downloading and uploading bandwidths to a great extent. Comparison of our new GIA-based live streaming system with the traditional GIA demonstrates that this system can achieve a significant improvement in total end-to-end delay, network throughput and redundancy of bandwidth usage.
