An important question in the development of system support for distributed multimedia is the type of network service offered to applications. This paper compares two network service disciplines: weighted fair queueing (WFQ) and non-preemptive earliest deadline first (NEDF). We show that, for a broad class of high-bandwidth distributed multimedia applications, WFQ outperforms NEDF in terms of network throughput while still providing an application-adequate end-to-end service. This result holds despite the fact that NEDF offers applications far greater flexibility in terms of control over end-to-end delivery delay
