NDN协议下的网络编码传输性能研究

Network Coding Transmission Performance Under the NDN Protocol

当前的信息爆炸时代使得海量数据集中出现,数据传输速率呈指数级增长,数据命名网络(named data networking,NDN)中特有的大数据量的计算与存储方式,传统的互联网体系架构已经无法满足大数据量网络的性能需求.本文在NDN网络中引入网络编码技术,拟解决NDN传输协议下的网络传输性能问题,着重探讨了时延以及吞吐量两个网络性能参数.实验结果表明网络编码机制下能够实现多播路由无法达到的吞吐量,而且将多播路由下的网络时延减小了将近50%,改进网络性能,节省了网络传输资源,满足当前处理大数据业务的要求.

The current era of information explosion makes the emergence of massive data,data transmission rate is growing exponentially,for NDN（named data networking）network specific amount of computing and large data storage,tradition internet architecture has been unable to meet the performance needs of large data networks.Delay is an important parameter to measure network performance merits,network coding can reduce network latency under the premise of guaranteed throughput.A network coding was introduced in NDN network,in order to resolve that network transmission performance problems under NDN transfer protocol,focusing on the two network performance parameters with latency and throughput.Experimental results demonstrate that the NDN combined with network coding can ensure high network throughput which multicast route can＇t attain,simultaneously reduce network latency with 50%,improve network performance,save the cost of network consumption,meet the current requirements of handling big data services.
