Abstract

A modular switch and a method that includes (a) first tier switching elements that comprise input output (IO) ports; and (b) second tier switching elements that are coupled to the first tier switching elements in a non-blocking manner. The first tier switching elements are configured to perform traffic management of traffic, and perform substantially all egress processing and ingress processing of the traffic; wherein the traffic management comprises load balancing, traffic shaping and flow-based reordering. The second tier switching elements are configured to (a) provide a shared memory space to the first tier switching elements, (b) perform substantially all of the queuing of traffic and (c) send, to the first tier switching elements, status information related to the status of shared memory resources. The first tier switching elements are configured to perform the traffic management based, at least in part, on the status information.
