This paper investigates the performance of the implementation of modified initial slow-start threshold size in Datagram Congestion Control Protocol (DCCP) TCP-like (CCID-2) over long delay link network.TCP-like is one of a congestion control mechanism for DCCP which is suitable for the delivery of multimedia data with abrupt changes during the transmission. The scenario is set for long delay link network,where the impact of the modified slow-start threshold value in TCP-like is significant.As a result, we managed to reduce the time required to obtain the maximum throughput in TCP-like during in the slow-start phase.The result shows that with the correct manipulation of initial slow-start threshold size for TCP-like, it will give a significant improvement to TCP-like performance over long delay link where the maximum throughput during the slow-start phase can be achieved faster.
