Considering that differential services (DiffServ) networking technologies are under development to support diverse quality-of-service (QoS) requirements, this letter provides the upper and lower bounds of the expected queue length for each priority class in a non-preemptive priority queueing system. The results illustrate the possible performance gain in terms of buffer requirement and/or waiting time that Diffserv networks can provide compared to those that do not support service differentiation.
