摘要
网络编码是改善组播通信性能的一种新技术。本文介绍了网络编码的概念,将网络编码的组播网络与现有IP组播网络进行性能比较,分析研究网络编码在吞吐量与流量负载平衡方面的性能改善。仿真结果表明,网络编码技术在传输最大流与改善网络链路的负载平衡方面具有较大的优势。
Network coding is a new technique which can improve the performance of multicast communications. Network coding conceptions are introduced, and the performances of network-coding multicast and those of existing IP multicast are compared. The benefits of network coding for multicast communication are analytically studied in throughput and traffic load balancing. The simulation indicates that network coding is more effective from the viewpoints of not only enabling max-flow transmission but also traffic load balancing in a network.
