A method for communicating between a first Fibre Channel (FC) enabled device and a second FC enabled device, where the communication occurs across a fabric that operates in accordance with a first protocol different from a FC protocol of the first and second FC enabled devices. The method includes receiving, from the first FC enabled device, at a first gateway receiver a sequence of bytes including at least one control character in accordance with the FC protocol. The method then includes replacing the at least one control character with at least one data character. The method also includes generating an encapsulation header and an encapsulation footer for encapsulating the sequence of bytes in which at least one control character was replaced with at least one data character. The method then includes setting a control character indicator in the encapsulation header if a first byte in the sequence of bytes received at the gateway receiver is a control character. The method includes setting an end of frame indicator in the encapsulation footer if a last byte in the sequence of bytes received at the first gateway receiver is an end of frame control character.

Encapsulating Fibre Channel signals for transmission over non-Fibre Channel networks

A method for communicating between a first device and a second device, wherein the communication occurs across a fabric and the first device is coupled to the fabric by a first gateway and the second device is coupled to the fabric by a second gateway. The method includes adjusting, at the first gateway, upon receipt of a first device readiness signal a first device readiness indicator to indicate an increase in a number of frames the first device is ready to accept, and sending, from the first gateway to the second gateway, a first gateway readiness signal, the first gateway readiness signal indicative of an increase in a number of frames the first gateway is ready to accept. The method then includes: receiving, at an input buffer of the first gateway from the second gateway, a first device frame; sending, from the first gateway to the first device, the first device frame when the first device readiness indicator indicates that the first device is ready to accept the first device frame; and adjusting, at the first gateway, the first device readiness indicator upon sending the first device frame to the first device to indicate a decrease in the number of frames the first device is ready to accept.
