Impact of Packet Size on Performance of TCP traffic with Small Router buffers

Abstract

In this paper, we research the impact of packet size on the performance of TCP traffic with small router buffers. First of all, we established a simple model which had two TCP flows, combined with the queue management mechanism in a router and analyzed the effect on TCP packet loss performance of variable packet sizes. Secondly, the corresponding network topology was established based on the NS2 simulation software. And the correctness of the model was verified by experiments.
