Abstract:
1. A path switching control system for controlling path switching, comprising: an active path control unit for controlling active paths; a standby path control unit for controlling standby paths; and a path switching control unit being configured in hardware and for controlling the path switching, wherein the path switching control unit includes: a control information reading unit for reading control information from the active path control unit on the occurrence of a failure in the active path control unit; and a control information writing unit for writing the control information read by the control information reading unit into the standby path control unit, wherein: the active path control unit and the standby path control unit are configured in Field Programmable Gate Arrays; the control information reading unit reads the control information from the active path control unit using a readback capability of the Field Programmable Gate Array; the path switching control unit is connected to the active path control unit via a configuration bus to set configuration of the active path control unit and the standby path control unit; and the control information reading unit reads the control information from the active path control unit via the configuration bus.
