In this paper, TCP performance over OBS networks with multiple TCP input flows is evaluated. A new burst assembly
method is put forward to improve TCP performance on OBS networks. Normally, TCP packets are assembled by only
one assembly queue, increasing the number of the burst assembly queues will affect the TCP performance. Simulation
results show that when using time and burst-length threshold, according to burst-length threshold, different number of
burst assembly queues should be chosen to get better TCP performance.
