| 摘 要： | 为了提高数据包在云计算数据中心中基于虚拟机构成网络中的传输性能,提出了一种基于网络编码的高效数据包传输方法.基于网络编码机制,采用对传输过程中丢失数据包高效的编码组合策略,多个虚拟机终端可以在一次多播或广播传输中获取多个从交换机优先传输的数据包,因此,提出的方法可以提高基于虚拟机网络的多播及广播业务的数据包传输延迟,并提高多播及广播业务的网络吞吐量.仿真结果表明提出的方法在典型信道条件下均获得了较好的数据包传输时延及网络吞吐量性能.

| Abstract: | A high efficient transmission scheme based on network coding （NC） is proposed for Virtual Machine （VM） based Networks in Cloud Computing Data Center to improve packet transmission performance. By employing NC mechanism with an efficient combination strategy of lost packets,the VMs can obtain more packets preferentially transmitted from switch via one transmission, thus the proposed scheme is designed to improve packet transfer delay, as well as network throughput for muhicast broadcast services in VM based networks. Simulation results show the effectiveness of the proposed scheme under typical channel conditions. |
