SIMULATION STUDY OF PERFORMANCE OF PACKET DISCARD SCHEME IN ATM SWITCHES
分组丢弃算法性能仿真研究

The throughput and fairness of EPD and PPD schemes are studies in the environment of heterogeneous traffic and in the environment of time-varying available bandwidth. The queuing system with EPD algorithm gives higher goodput to the sources near it, and the sources far away from the system will have lower goodput. Study of this paper further finds a practical way to solve this unfairness.
