基于网络态势的栅格网多径并行传输算法

Multi-path Concurrent Transfer Algorithm in Grid based on Network Situation

栅格网将各种通信资源通过虚拟化技术融合在一起,以统一的网络态势为上层应用提供服务。利用栅格网的特点,提出基于网络态势的多径并行传输算法,将通信业务合理分配在多条并行路径上进行传输,或将多条较低带宽的路径虚拟为一个较高带宽的端到端路径来提供服务,适用于战术通信环境等具有较多低带宽链路的栅格网络,仿真结果表明该算法可大大提高网络吞吐量和资源利用率。

Grid networks aggregate all communication resource by virtualization and provide services for applications by uniform network situation. Based on the advantage of grid networks, a multi-path concur- rent transfer algorithm is introduced. The algorithm can divide a big service flow to multi-path to transfer concurrently, or aggregate many low bandwidth path to a high bandwidth path for end-to-end service. The algorithm can be used in the network which has many low bandwidth channels such as tactics grid net- work. The results of simulation indicate the algorithm can improve network throughput and resource utilization.
