TCP Vegas-O:a New Improved Algorithm of TCP Vegas Based on Delay Estimation
Peng Li · Microelectronics & Computer · 2009
TCP Vegas to change from slow-start phase to congestion avoidance phase too early,and congestion window is too small resulting in bandwidth utilization is dropping,and so on with Reno congestion based on packet loss to determine when the algorithm competitive bandwidth resulting in fairness badly.The paper on the slow start and congestion avoidance phases corresponding improvement,and finally to combine.By the simulation results show that the slow start algorithm too early end and bandwidth fairness of TCP Vegas,such as defects in agreement with the marked improvement,especially in the high-bandwidth delay product networks.
