In numerous TCP congestion control algorithms, TCP Vegas avoids congestion on its own initiative. However, its slow-start ending quickly and growing unsmoothly cause that the congestin window designing too small and bandwidth utilization declining too rapid, furthermore affect network efficiency and throughput dropping. . . etc. Aimed at the deficiencies, we propose a kind of Logarithmic Slow-Start Algorithm of TCP Vegas (LSSA-TCP Vegas) to conduct the dynamics of congestion window. We analyze

Our goal in this paper is to study and compare the performance of LSSA-TCP Vegas and other TCP congestion control algorithms under various network scenarios. The simulation results demonstrate that the algorithm vs the bug of TCP Vegas contains obvious improvements. We believe that Logarithmic Slow-Start Algorithm can be used to provide the better performance of TCP Vegas.
