Studies on the Performance Improvement of Window Adjustment Procedure in High Bandwidth Delay Product Network

High bandwidth environment is useful for sending large volumes of data within short period of time. As there is a growing demand for high bandwidth networks, data transfer must take place without any congestion. Hence attempts have been made to find a suitable window adjustment procedure for congestion avoidance. In TCP, since window size is usually increased by 1 MSS/RTT and halved upon packet losses in any network, it is not suitable for high speed network. In this paper a study is made on window adjustment procedure for high bandwidth networks using XCP protocol. The window adjustment procedure is based on the queue and admitted rate .This proposed idea will be useful for high bandwidth environment for congestion avoidance.
