Abstract: This paper addresses scheduling and memory management in input queued switches having fnite buffer with the objective of improving the performance in terms of throughput and average delay.Most of the prior works on scheduling related to input queued switches assume infinite buffer space.In practice,buffer space being a finite resource,special memory management scheme becomes essential.

Key words: buffer memory management, switches, scheduling

摘要: 介绍了一种基于有限缓存的输入队列交换机的集成调度和缓存管理策略(ISMM),该方案在吞吐量和平均延迟两项性能指标上有了很大改善。以前的许多关于输入队列交换机的调度方案都是在无限缓存的前提下完成的,但实际上,缓存是一种有限的资源,因此缓存管理方案就非常重要。
