摘要
随着网络带宽的不断提升,基于并行TCP的应用方式得到广泛使用。当节点为同一个应用打开多个TCP连接时,对于使用单一TCP连接的网络用户存在严重的不公平。提出一种基于强度控制的并行TCP拥塞控制方案TCP-C,使这些TCP流共享拥塞信息,同时限制并行TCP流的有效连接数量,以控制并行流的侵略性。实验结果显示该方案能够较好地保证公平性,同时有效地利用网络带宽。
The applications based on parallel Transmission Control Protocol (TCP) are widely used with the increase of network bandwidth. When the nodes open seveval TCP connections for one application, it is unfair for the nodes that use single TCP connection. TCP-C, a parallel TCP congestion control scheme based on the strength control, was proposed. In this scheme, the TCP connections share the congestion information and restrict the available connection number to control the aggressiveness of the parallel flows. The experimental results show that TCP-C can ensure the fairness while effectively using the bandwidth.
