  • Method and system for negotiation of the highest common link rate among nodes of a fibre channel arbitrated loop
    Patent number: 6477171
    Abstract: A method and system for automatic negotiation of maximal shared data transmission and reception rates by fibre channel nodes in a fibre channel arbitrated loop. An auto-speed-negotiation function is included in the fibre channel arbitrated loop initialization procedure. A fibre channel node undergoing initialization turns off its transmitter in order to elicit a loss of synchronization condition in the next fibre channel node of the arbitrated loop. Upon detection of loss of synchronization, each subsequent fibre channel arbitrated loop node invokes the auto-speed-negotiation function. The fibre channel node then turns its transmitter back on at the highest possible data transmission rate, sets the data reception rate of the fibre channel node's receiver to the lowest possible data reception rate, and then waits to detect word synchronization by the receiver.
