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.
