摘要: CICQ (Combined Input and Cross-point-Queued switch)交换机是一种在交叉点缓存加入少量缓存的交换结构，是当前研究的一个热点。该文研究了基于交叉点缓存的各种调度算法和基于CICQ的交换结构，提出了LFF-LBF算法，运用通畅度和拥塞度两个概念，保证了最急迫的信元被最先服务。仿真分析表明该算法在均匀分布和突发业务源的情况下具有良好的时延性能和稳定性能。

Abstract: CICQ (Combined Input and Cross-point-Queued switch) is a fabric system with buffers in cross-points, which is a hotspot in switching area. In this paper, we analyze the current situation, and presented the LEF-LBF scheduling algorithm based on the two conceptions of congestion degree and unblocking degree to serve the urgent cells first. The simulation results show that LFF-LBF can offer very good performance on average delay and stability for uniform traffic with Bernoulli and burst arrivals. -
