Abstract
As the Internet infrastructure evolves to include Quality of Service (QoS), it is necessary to map application quality requirements to the the network performance specifications in terms of delay and loss rate. While past work has addressed the dependency of audio and video applications on these underlying QoS metrics, little work has been done in the area of Web traffic. In this paper, we use a combination of emulation, simulation, and analysis to quantify the effect of network performance metrics on HTTP request latency and the perceptual quality of an audio application. Although our work is done in the context of a LAN environment, the results generalize to a more general WAN environment. Our contributions are three-fold. First, we combine simulation and emulation techniques in setting up an accurate yet controllable testbed. The use of network simulator Entrapid [10] [14] and its built-in Fast Ethernet Simulation [34] makes our simulation both efficient and accurate. Second, for W...
