Abstract

Examples are disclosed for forwarding data partitioned into one or more cells through at least a portion of a three-stage memory-memory-memory (MMM) input-queued Clos-network (IQC) packet switch. In some examples, each module of the three-stage MMM IQC packet switch includes a virtual queue and a manager that are configured in cooperation with one another to forward cells through at least a portion of the switch. The cells may have been partitioned and stored at an input port for the switch and destined for an output port for the switch.

Description

[0001] related application [0002] This application claims U.S. Application Serial No. 12 / 511,814, filed July 29, 2009, by Roberto Rojas-Cessa and Ziqian Dong, entitled "Forwarding Data Through a Three-Stage Clos-Network Packet Switch with Memory at each Stage." number priority. This application is also related to U.S. Application Serial No. 12 / 485,828, filed June 16, 2009, by Roberto Rojas-Cessa and Chuan-bi Lin, entitled "Configuring a Three-Stage Clos-Network Packet Switch;" and to U.S. Application Serial No. 12 / 511,424, filed July 29, 2009, by Roberto Rojas-Cessa and Ziqian Dong, entitled "Forwarding Cells of Partitioned Data Through a Three-Stage Clos-Network Packet Switch with Memory at each Stage." No. Background technique [0003] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
