Abstract:
1. A method of managing a communications link in which a first device interfaces with a first channel extender and in which a second device interfaces with a second channel extender, and in which the first and second channel extenders communicate with each other through a communications medium, the method comprising: monitoring an occupancy of a receive buffer in the first channel extender during transmission from the second channel extender at a first transmission rate; at a first time when the occupancy of the receive buffer exceeds a first threshold, immediately instructing the second channel extender to cease transmission to the first channel extender; monitoring for an overflow condition in the receive buffer; d) if the overflow condition is present, specifying that a future transmission to the first channel extender be at a second transmission rate that is lower than the first transmission rate; and instructing the second channel extender to resume transmission to the first channel extender after the step of instructing the second channel extender to cease transmission to the first channel extender, rf is a Fibre Channel line rate; sf is a Fibre Channel frame size; and Γ
