Supplemental flow control mechanisms are provided to facilitate efficient da ta exchange between Fibre Channel ports over extended distances. In one implementation, a supplemental buffer mechanism is maintained and managed in part by substituting a locally generated ready indication signal for the remotely generated ready indication signal provided by the Fibre Channel standard. In this way, data flow may be adjusted optimally irrespective of t he relatively long propagation time of the ready signals exchanged by the two sides of the link.
