多路径负载均衡性能仿真分析

Simulation and Analysis on Performance of the Multi-path Load Balance

在网络拥塞条件下进行大数据量的文件传输时,单一传输路径会导致较长的文件下载响应时间.在计算机网络仿真平台上,设计了开放式最短路径优先(OSPF)多路径负载均衡算法,得到了文件下载响应时间及链路吞吐量等网络性能参数.仿真表明:网络层采用多路径负载均衡技术的路由协议,可以优化网络资源利用率;传输层采用用户数据报协议(UDP),则可以进一步降低文件下载响应时间,提高网络性能.

If a large file transmitted in a condition of network congestion, It would caused very long file download response time with all packets are transferred from the source tO the destination via a single path. Open shortest path first algorithms with multi-path load balancing are designed on the computer network simulation platform, some network performance parameters such as file download response time and link throughput can be obtained. The results shows that network resources can be optimized by using multi-path load balancing protocol in the network level. If User Datagram Protocol （UDP） was used as transport protocol, we can get even fewer file download response time and thereby network performance was improved.
