摘要

提出了一种综合考虑缓冲区管理和调度机制的输入队列交换机队列长度比例(QLP)分配算法，以便根据实际流量负载对带宽和缓冲空间进行最优分配。通过考虑带宽和积压队列长度来实现带宽分配，从而可以同时获得高吞吐量和低单元损失率。与将缓冲区管理和调度作为独立功能处理的方法相比，QLP能够最大限度地提高总体吞吐量并提高缓冲区利用率。

QLP: a joint buffer management and scheduling scheme for input queued switches

We propose the queue length proportional (QLP) assignment algorithm for input queued switches that considers buffer management and scheduling mechanism inclusively to obtain an optimal assignment of both bandwidth and buffer space according to the real traffic load. The bandwidth assignment is implemented by considering both bandwidth and backlogged queue lengths, so that it is possible to obtain a high throughput as well as a low cell loss ratio at the same time. QLP is shown to be able to maximize overall throughputs and improve buffer utilization as compared to those which treat buffer management and scheduling as separate functions.
