Abstract
In these days, the deployment of Diffserv (Differentiated Services) that enables the QoS guarantee is urgently required by the IP network customers. However, AF (Assured Forwarding) PHB (Per Hop Behavior) in Diffserv still has not been provided by conventional routers. It is a realistic solution that SBR3 (Statistical Bit Rate 3) of ATM emulates AF PHB, but it is not clear whether TCP traffic over AF PHB emulated by ATM is differentiated from the best effort TCP traffic over DF (Default Forwarding) PHB. To confirm the differentiation, we have experimentally studied TCP performance through the link into which TCP connections over AF PHB and DF PHB is aggregated. This paper describes the experimental results and discusses the possibility of the TCP performance differentiation between AF PHB and DF PHB over ATM.
