CREDIT MANAGEMENT FOR DATA FLOW BETWEEN TWO NETWORKS

摘要

A method for communication between a first device and a second device (212), wherein the communication occurs across a fabric (210) and the first device (202) is coupled to the fabric (210) by a first gateway (208) and the second device (212) is coupled to the fabric (210) by a second gateway (208). The method includes adjusting, at a first gateway, upon receipt of a 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 indicative of an increase in an amount 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; and adjusting 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.
