    摘要: In a network system for transporting GFP-encapsulated Fibre Channel/FICON data across a SONET/SDH transport network between two Fibre Channel/FICON ports, a transport interface for one Fibre Channel/FICON port intelligently allocates the amount of buffers for receiving Fibre Channel/FICON data from the other Fibre Channel/FICON port by determining the latency of travel across the SONET/SDH transport network. The first transport interface inserts a special latency instruction message into the Fibre Channel/FICON data before encapsulation in a GFP frame. After transport across the SONET/SDH network, the receiving second transport interface immediately sends the special latency instruction message back across the SONET/SDH transport network to the first transport interface which times the return of the special latency instruction message. From the time interval, the first transport interface can determine the latency of the SONET/SDH transport network and allocates the amount of buffers appropriately. This latency determination procedure is performed periodically so that the amount of allocated buffers can change as the latency of the SONET/SDH transport network changes.

    摘要: 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.

    摘要: A method and system for emulating an Fibre Channel link over a SONET transport path by which Fibre Channel data is transported across the SONET/SDH transport path. To provide link integrity, techniques to handle link failures from a Fibre Channel element to its associated Fibre Channel port, or of the SONET/SDH network linking Fibre Channel ports include transmitting error condition codes over the SONET/SDH transport path overhead to a remote Fibre Channel transport interface so that the Fibre Channel link from the remote Fibre Channel transport interface to the associated remote Fibre Channel port is disabled. Timing the length of failures and return of operation of the failed links is used to handle transient conditions and to avoid link bouncing.
