Abstract

Networked applications require good performance from the network along with a high level of predictability. One of the factors that affects application performance is the packet dropping policy adopted in the switch or router. In this paper, we evaluate the absolute performance of various packet dropping policies, and also the predictability they can provide to an application. The packet dropping schemes studied are the partial packet discard (PPD), early packet discard (EPD), age priority packet discarding (APPD) and the preemptive partial packet discard (pPPD). Results are provided in multi-hop networks for different traffic types, including IP over ATM trace data
