A real-time end-to-end testbed for evaluating the performance of multimedia services

Abstract

In this paper, we describe a real-time testbed used to assess the end-to-end performance for multimedia services. This testbed uses network performance indicators to emulate the behavior of any network type (fixed, cellular, etc.). Application performance indicators can be evaluated by running a multimedia service on top of the emulated network. A user is able to experience real-time the subjective quality of any multimedia service running over whatever network. In this paper, we describe the testbed architecture and evaluate the performance of streaming services over future wireless networks, based on 3GPP Long Term Evolution (LTE). © 2009 Springer Berlin Heidelberg.
