Current MSM switching fabric has poor performance under unbalanced traffic. This paper presents an alternative, novel Central-stage Buffered Three-stage Clos switching (CB-3Clos) fabric and proves that this fabric can emulate output queuing switch without any speedup. By analyzing the condition to satisfy the central-stage load-balance, this paper also proposes a Central-stage Load-balanced-baseddistributed Scheduling algorithm (CLdS) for CB-3Clos. The results show that, compared with Concurrent round-robin baseddispatching (Crrd) algorithm based on MSM, CLdS algorithm has high throughput irrespective with the traffic model and better performance in mean packet delay.

In order to improve the survivability of IP networks, this paper presents a fast self-healing mechanism fordistance vectorrouting protocol called FS-dVP.(Fast Selfhealing distance vector protocol). The mechanism can dealing with network failures effectively through the precomputed multiple feasible next hops perdestination. This local rerouting scheme guarantee the forwarding continuity in the convergence period. FS-dVP suppression of its failure notification to provides better stability andreduce network overhead of message updates. Simulations performed show that FS-rIP can dealing with the simultaneous failures of multiple arbitrary links effectively and can effectively improve network stability and availability.
