Abstract or Description

Abstract: "We present a general analytical framework for the modeling and analysis of TCP variations. The framework is quite comprehensive and allows the modeling of multiple variations of TCP, i.e. TCP-Vegas, TCP-SACK, and TCP-Reno, under very general network situations. In particular, the framework allows us to propose the first analytical model of TCP-Vegas under on-off traffic -- all existing analytical models of TCP-Vegas assume bulk transfer only. All TCP models are validated against event driven simulations (ns-2) and existing state-of-the-art analytical models. Finally, the analysis provided by our framework leads to many interesting observations with respect to both the behavior of bottleneck links that are shared by TCP sources and the effectiveness of the design decisions in TCP-SACK and TCP-Vegas."
