what level of estimating accuracy does tcp need and can tcp achieve
Accurate and effective estimation of TCP operating point impacts directly on TCP performance, especially in modern high-speed networks. In this paper, we focus on two crucial questions: 1) In order to guarantee the performance and stability of TCP, how accurately does the TCP operating point need to be estimated? 2) Ahead of the occurrence of network congestion, how accurately can TCP estimate its operating points at the end host? We declare that the estimator which is based on TCP packet series can satisfy the accuracy TCP required.
