摘要
提出了根据网络信息状态通过SDN控制器来控制MPTCP流量以提高并行传输速率。利用所提出的最宽不相交选路算法,为每个MPTCP连接选择一组可用带宽最宽且链路差距较小的路径集;然后使用可用路径容量的比例作为流量分配到该路径上的概率,进一步减小子流的带宽差距;最后,通过搭建Floodlight仿真实验平台,证明方案能够避免MPTCP的不同子流经过同一路径,并有效地利用路径提升并行传输效率。
This paper proposed to control the MPTCP traffic through the SDN controller to improve the parallel transmission rate according to the network state.This paper used the proposed widest disjoint routing algorithm,it chose a set of available path sets with the widest bandwidth and a smaller link gap for each MPTCP connection,and then it used the ratio of the available path capacity as the probability that the traffic was allocated to the path,further reduced the bandwidth difference of the subflow.Finally,by setting up the Floodlight simulation experiment platform,the result proves that the scheme can avoid different paths of MPTCP going through the same path,and effectively use the path to enhance the parallel transmission efficiency.
