Abstract

A novel solution to fast network restoration is provided. In a network node, a Connection Manager (203) and an Equipment Manager (204) are utilized to implement restoration, ands these elements are linked via a specialized high speed bus (201). Moreover, the incoming and outgoing optical signals (200A, 200B, 200AA, 200BB) to each input/output port (206, 207) are continually monitored (220, 221) and their status communicated to the Connection Manager (203) and Equipment Manager (204) via the high-speed bus (201). This provides a complete snapshot in virtually real time of the state of each input port (206) on the node, and the switch map (205) specifying inter portal connections, to the dedicated control and restoration hardware (203, 204). The specialized hardware (203, 204) detects trouble conditions and reconfigures the switching fabric (210). The invention enables a very fast and efficient control loop between the I/O ports (206, 207), switch fabrics (210), and controllers (203, 204).
