A New CICQ Fabric Based on State of Cross-point-Buffer
一种基于缓存状态的CICQ交换机

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.
