Abstract

This article presents a framework, based on FPA (Fixed Point Approximation), to analyze node performance in an IP network with a single congested router using WFQ (Weighted Fair Queueing) scheduler loaded by short connection TCP trafﬁc. The objective of this paper is to obtain RTT (Round Trip Time) values, packet loss prob ability, and TCP transfer latencies. Simulations using the Network Simulator (NS-2) are also conduced in order to validate the results.
