Abstract
In recent years, the Internet spreads widely, and Broadband communication services, such as ADSL and B Flet’s, become common to end users. As a result, packet loss and the fall of throughput, caused by the increase of router loads, come into question. To solve these problems, we focus on current TCP congestion control, which does not address the state of network congestion adequately, and suggest two new congestion control technique-rewriting header information of TCP packet by router, considering the state of network, and then evaluate its performance by simulation. The result demonstrate the effectiveness of proposing technique.
