Abstract
A Switch Fabric system comprising at least one Switch Fabric subsystem (100, 200) further including a set of Switch cores elements (111, 112, 121, 122) that are mounted in a port expansion permitting attachment of at least a first and second sets of Protocol Adapters (1, 2) under a routing control process. A Primary Switch controller (PSC) has a complete knowledge of the topology of the switch, e.g., the number of subsystems, the nature of the port expansion etc., while each Secondary Switch Controller only has a limited knowledge of that topology. One particular Switch Core (111, 211) which has a full-duplex communication capability in each Subsystem is assigned the key function to interface communication between the PSC and the other SSC in a same Switch Fabric Subsystem.
