Abstract Optical Burst Switching (OBS) is a promising paradigm for the next-generation internet infrastructure. Based on analyzing the influence of the special transmission mode in Optical Burst Switching (OBS) networks upon the performance of TCP, this paper studies the impact of the number of TCP/IP packets of same connection assembled in one burst on the performance of TCP Reno throughput. A closed form equation is obtained which represents the relationship between the throughput and the burst loss rate, number of TCP/IP packets contained in one burst, and the Round Trip Time (RTT). The correctness of the analysis is then tested by simulation. Both the results of analysis and simulation show that an optimum number of TCP/IP packets of same connection assembled in one burst exists to make the TCP throughput maximum when the access link bandwidth is relatively large.
