THE EFFECT OF STREAMING MEDIA UDP TRAFFIC ON TCP/IP PERFORMANCE

Abstract

Emerging streaming media applications primarily use UDP as their transport. These are non-congestion controlled and have negative effects that range from extreme unfairness against competing TCP flows to potential congestion collapse. In Internet environments such as the Internet backbone, various ISPs, and DSL access networks that rely on ATM as their layer 2 transport technology, ATM's available bit rate service can effectively address these problems. ATM ABR uses rate based controlled algorithms to prevent congestion collapse and provide fairness among competing flows. Through simulation we showed the problems of congestion collapse and unfairness among competing flows and ATM ABR's ability to address these problems. fl
