Abstract:
1. A method comprising: receiving at a transport interface device Fibre Channel/FICON data from a local Fibre Channel/FICON port; inserting a special latency instruction message into said Fibre Channel/FICON data comprising a control character field, a special control character field, and a latency sequence number, wherein said control character field indicates that said special control character field contains a special control character, encapsulating said Fibre Channel/FICON data in a generic framing procedure (GFP) client data frame; sending said GFP client data frame over a SONET/SDH transport network to a remote Fibre Channel/FICON port; starting a timer concurrently with said sending of said GFP frame for timing a return of said special latency instruction message over said SONET/SDH transport network to produce a round trip time; calculating a number of buffers needed for receiving GFP client data frames from said remote Fibre Channel/FICON port in order to maximize throughput and reduce latency based on said round trip time; and allocating said number of buffers in said transport interface.
