Abstract

A network of switches that employ Registered State Change Notifications (RSCNs) with enhanced payloads is disclosed. In one embodiment, the network comprises multiple switches coupled together, and multiple node devices each directly-coupled to at least one other switch. Each of the switches preferably provides RSCNs to other switches when a node device state change is detected. One or more of the RSCNs preferably includes a device entry having more than four properties associated with the node device undergoing the state change. The switches receiving the enhanced RSCNs preferably maintain caches of remote node device entries copied from the RSCN device entries. The device entries preferably include one or more of the following: Owner Identifier, Port Type, Port Identifier, Port Name, Node Name, Initial Process Associator, Node IP Address, Class of Service, FC-4 Types, Port IP Address, Fabric Port Name, and Hard Address. Traffic overhead may advantageously be reduced.
