Rate and Delay Guarantees Provided by Clos Packet Switches With Load Balancing
The size of a single hob cross bar fabric is still limited by the technology it does not exceed the terabit capacity. The multihop fabric provides the higher capacity by using the switching elements. The traffic load is balanced at the middle stage switches, all the the traffic will get through as long as the out put not overloaded. However, the delay that packets experience through the Clos switch depends on the granularity of flows that are balanced. We examine the maximum fabric utilization under which a tolerable delay is provided for various load balancing algorithms, and derive the general formula for this utilization in terms of the number of flows that are balanced. We show that the algorithms which balance flows with sufficiently coarse granularity provide both high fabric utilization and delay guarantees to the most sensitive applications. Since no admission control should be performed within the switch, the fast traffic-pattern changes can be accommodated in the proposed scalable architecture.
