ABSTRACT:
Fiber-Channel links are carried over transport networks such as optical transport networks. In certain embodiments, available transport network capacity is over-subscribed by Fiber-Channel links. This may be accomplished by buffering Fiber-Channel traffic at the ingress of the transport network and selecting frames to inject into the transport network from the buffers. Transport network efficiency can therefore be greatly increased by use of statistical multiplexing. Ready signals from the receiving Fiber-Channel ports may be delayed before being relayed to the transmitting Fiber-Channel ports.
