Abstract
A system and method are provided for communicating control information in a switch fabric. The method comprises: on a switch card, establishing a plurality of crossbars controlled by an arbiter; initiating a control message; and, distributing the control message on a switch card token bus connecting the crossbars and arbiter elements. Distributing the control message on a switch card token bus connecting the crossbar and arbiter elements includes daisy-chain connecting the elements with a cyclical bus. In some aspects of the method, establishing a plurality of crossbars controlled by an arbiter includes identifying each element with a unique address. Then, initiating a control message includes initiating a control message with an attached address. Distributing the control message on a switch card token bus includes the substeps of: daisy-chain passing the control message between elements; and, terminating the message at an element having an address matching the address attached to the control message.
