Method and system for efficient link recovery for fibre channel over SONET/SDH transport path

A method and system for flow control of GFP-encapsulated Fiber Channel frames over SONET/SDH transport networks is described. Transport interfaces, in the form of port cards, monitor any switch-over or error in the SONET/SDH transport network responsive to GFP out of synchronization signals; and tra...

Zusammenfassung:	A method and system for flow control of GFP-encapsulated Fiber Channel frames over SONET/SDH transport networks is described. Transport interfaces, in the form of port cards, monitor any switch-over or error in the SONET/SDH transport network responsive to GFP out of synchronization signals; and transmit Fiber Channel Ordered Sets indicative of non-operation to it associated Fiber Channel port so that the Fiber Channel port performs link initialization and buffer credit recovery procedures with its counterpart Fiber Channel port across the SONET/SDH transport network. This speeds the recovery of the link between the two Fiber Channel ports.
