The method for improving TCP performance in bandwidth-guaranteed network

Abstract

This paper discusses the efficiency of TCP transmission over a bandwidth-guaranteed network, where the bandwidth for each flow is guaranteed by traffic policing at edge nodes. In particular, it explores a method for improving TCP performance focusing on the size of the buffer to absorb jitter and promote a faster increase in the congestion window size. We propose a rate control method at an edge node based on controlling the advertised window for improving TCP performance in a bandwidth-guaranteed network. We also evaluate the effectiveness of the proposed method using a prototype.
