We present an analytical model, based on a Fixed Point Approximation (FPA) solution, that can be used to derive the performance of different sets of TCP connections that share, and compete for, a common resource, typically a link and its associated buffer. A set of TCP connections is a group of connections that can be considered homogeneous, e.g., they have similar RTTs and all have a wireless access. TCP connections are modeled through the OMQN (Open Multiclass Queueing Network) paradigm. The conditions that define the feasibility of the solution and allow the convergence of the model are discussed and an application example with a RED buffer where wired and wireless connections converge is presented.

Abstract

We present an analytical model, based on a Fixed Point Approximation (FPA) solution, that can be used to derive the performance of different sets of TCP connections that share, and compete for, a common resource, typically a link and its associated buffer. A set of TCP connections is a group of connections that can be considered homogeneous, e.g., they have similar RTTs and all have a wireless access. TCP connections are modeled through the OMQN (Open Multiclass Queueing Network) paradigm. The conditions that define the feasibility of the solution and allow the convergence of the model are discussed and an application example with a RED buffer where wired and wireless connections converge is presented.
