Abstract

In TCP over OBS networks, the parameters from both of TCP and OBS layers will affect the network performance when supporting the upper layer applications, such as Grid application. According to our previous work, we found that TCP window is the key limitation for such a network to support Grid application. The embedded AIMD model of TCP is too conservative. Especially in the network with high bandwidth-delay product scenario, it will take TCP a long time to increase the TCP window according to the slow start and the congestion avoidance rules. In this paper, according to the established analytical model, the TCP window size is optimized in Grid over OBS network. The analytical results show that the optimization of TCP window can improve the TCP throughput significantly.
