Patent ID: 8644148

Claim:
A method comprising: receiving, at a switch, a first end-to-end flow control representation for at least one logical connection from a first apparatus to a second apparatus. wherein the first apparatus is subject to a first link, wherein the second apparatus is subject to a second link, and wherein the second link is of lower performance than the first link; updating, at the switch, at least one end-to-end credit value, the at least one end-to-end credit value associated with one of the at least one logical connection from the first apparatus to the second apparatus based on the first end-to-end flow control representation; selecting, at the switch, at least one of the at least one logical connection from the first apparatus to the second apparatus based on an associated end-to-end credit value, wherein said selection is carried out based on organized granting by said switch; generating, at the switch, a second end-to-end flow control representation for the at least one of the at least one logical connection from the first apparatus to the second apparatus; and determining to transmit, from the switch, the second end-to-end flow control representation addressed to the second apparatus, wherein the switch bridges end-to-end flow control of said first link and end-to-end flow control of said second link.
