Abstract
The Fibre-Channel flow control 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 an interface to a transport network used to carry Fibre-Channel traffic. The transport network interface makes a remote Fibre-Channel port aware of the augmented local receiver buffer capacity by intercepting certain frames used in link establishment and substituting an enhanced buffer capacity for the local Fibre-Channel port's internal buffer capacity. This technique provides improved throughput and readily accommodates large distances and large frame sizes.
