SIGNAL LINK CONNECTION METHOD BETWEEN SWITCH NODES

摘要

PROBLEM TO BE SOLVED: To provide a signal link connection method between switch nodes by which a network band required for signal link connection between communication controllers can be reduced. SOLUTION: The two sets of the identical communication controllers are placed in the switch node, the one controller is used as an active controller and the other is used as standby controller, and the active controller is used to make signal line connection with a communication controller of other switch node.
