Apparatus and method for redundancy control of duplex switch board

摘要

An apparatus and method for a redundancy control in duplex switch boards in a high speed network system are provided. The apparatus includes: a switching unit for switching data inputted one of the duplex switch boards to a destination line card; a state controlling unit for controlling a clock state of an opponent switch board between the duplex switch boards; an IPC controlling unit for controlling an inter processor communication (IPC) of a platform of the communication network system; a processing unit for controlling the IPC controlling unit and the state controlling unit of the duplex switch boards; and a clock controlling unit for synchronizing a clock between the duplex switch boards.
