Improvement of TCP Algorithm and Model Analysis Under Bandwidth-guaranteed Services
Yan Rong Wei · Jisuanji gongcheng · 2003
DiffServbased bandwidthguaranteed services have been gradually deployed in the Internet, achieved by packet marking and dropping mechanism. Although the guarantee is not hard, the service is easy and extended. However, TCP protocols residing in host ends have no idea about the contract bandwidth, they cannot realize bandwidth offered by the network. This paper proposes a new TCP congestion control algorithm based on analysis of twowindow TCP congestion control algorithm, and verifies it by simulation tests and modeling. The proposed algorithm is simple and convergences rapidly when network is undergoing a burst congestion.
