Description
ウィンドウ型のフロー制御方式は、フィードバック型の輻輳制御方式であり、現在のTCP/IPネットワークにおいて広く利用されている。最近提案されたTCP Vegasは、現在使用されているTCP TahoeやTCP Renoに比べてより高い性能を示す可能性を持っている。本論文では、TCP Vegasの輻輳回避機構にもとづいた、ウィンドウ型のフロー制御方式に注目する。まず、制御理論を適用することによって、その安定性解析を行う。次に、シミュレーションによって、TCP Vegasから引き継がれた、ウィンドウ型フロー制御方式のいくつかの問題点について検討を行う。さらに、ECN (Explicit Congestion Notification)を用いることによって、指摘した問題点が解決されることを示す。
A window-based flow control mechanism is a sort of feedback-based congestion control mechanisms, and has been widely used in TCP/IP networks. Recently proposed TCP Vegas is another version of the TCP mechanism and has potential to achieve much better performance than current TCP Tahoe and Reno. In this paper, we focus on a window-based flow control mechanism based on a congestion avoidance mechanism of TCP Vegas. We first present a control theoretic analysis for its stability. We then discuss several drawbacks of the window-based flow control mechanism, being inherited from TCP Vegas, through simulation experiments. We finaliy investigate how these drawbacks are solved by incorporating the ECN (Explicit Congestion Notification) mechanism into the window-based flow control mechanism.
