摘要
Considerable recent work has explored the queueing impact of different properties of the input process to a buffer. The authors confine their attention to the effects of variation in service time distribution: the motivation for this being the need to calculate accurate delay bounds in the presence of variable length IP packets, and specifically to assess the impact of a small proportion of large packets on the delay performance. An analytical result is developed into which any distribution of packet size can be substituted easily, and in the process the value of better queueing models for arbitrary packet length distributions is shown.
