Abstract

We analyze and characterize the performance of TCP/IP over the point-to-point protocol (PPP) over ATM using asymmetric links in the presence of multiple clients competing for bandwidth. This is part of an ongoing research project that studies techniques to provide end-to-end quality of service to flows when ADSL is used in the access network. The results presented illustrate the decrease in fairness and the link utilization that occurs in the presence of both bi-directional and unidirectional flows in an ADSL environment
