FLOW CONTROL MANAGEMENT TO EXTEND THE PERFORMANCE RANGE OF FIBRE CHANNEL LINK

摘要

Supplemental flow control mechanisms are provided to facilitate efficient dataexchange between Fibre Channel ports over extended distances. In oneimplementation, a supplemental buffer mechanism is maintained and managed inpart by substituting a locally generated ready indication signal for theremotely generated ready indication signal provided by the Fibre Channelstandard. In this way, data flow may be adjusted optimally irrespective of therelatively long propagation time of the ready signals exchanged by the twosides of the link.
