Abstract | The feedback-based two-stage switch does not require a central scheduler and can provide close to 100% throughput [3]. But the number of crosspoints required for the two stages of switch fabric is 2N2, and the average packet delay performance (even under light traffic load) is on the order of O(N) slots, where N is the switch size. To improve the performance of feedback-based two-stage switch when N is large, we adopt the Clos network for constructing a large switch from a set of smaller feedback-based switch modules. We call it a Clos-feedback switch. The potential problem of packet mis-sequencing is solved by using application-flow based load balancing. With recursive decomposition, a Clos network can degenerate into a Benes network. We show that for a Clos-feedback switch, the number of crosspoints required is reduced to 4N(2 log2N-1) and the average packet delay is cut down to O(log 2 N) slots. © 2012 IEEE. |
