APPARATUS AND METHOD FOR DISTANCE EXTENSION OF FIBRE-CHANNELOVER TRANSPORT

摘要

The Fibre-Channel flow mechanism is augmented to facilitate efficient data exchange between Fibre-Channel ports over extended distances. A supplemental buffer mechanism may be maintained as part of the interface to a transport network used to carry Fibre-Channel traffic. The transport network interface 108 makes a remote Fibre-Channel port aware of the augmented local receiver buffer capacity by intercepting certain frames used in the link establishmen t and substituting an enhanced buffer capacity for the local Fibre-Channel port's internal buffer capacity.
