Abstract

We introduce a novel packet discarding policy called longest-packet-in (LPI) which maximizes the cell goodput, the ratio of outgoing good cells to the total number of cells that arrive at a queue. We compare LPI to tail drop, early packet discard, early packet discard with hysteresis and fair early packet discard with hysteresis by investigating the trade-off between maximizing the cell goodput and maximizing the packet goodput. Furthermore, we evaluate the impact of network load, mean packet size, and the Hurst parameter on both the cell goodput and the packet goodput
