摘要： A system, apparatus and method are described for controlling the gain across one or more amplifier nodes within an optical span. In one embodiment, a fast local amplifier constant gain control loop is provided that maintains a constant gain across an amplifier node for each of the channels within an optical signal. A slow link level gain setting control loop is provided to set and/or adjust the target gain on the amplifier node(s). A gain adjust sequence is performed by the slow link level gain setting control loop to adjust the target gain(s) in response to various events and mechanisms. A “time of flight” protection method is also provided to ensure consistency between the fast local amplifier gain control loop and the slow link level gain setting control loop.

摘要： A line card in a network node having a local memory coupled to a local controller and local logic circuit. The local memory in the line card stores state information for signals processed by the line card itself, as well as state information for signals processed by other line cards. The logic circuit and controller implement a same fault detection and signal processing algorithms as all other line cards in the group, to essentially effectuate a distributed and local hardware based control of automatic protection switching (APS) without interrupting a central processor. The line card also performs error checking and supervisory functions to ensure consistency of state among the line cards.

摘要： A network device may include a set of switches. Each of the switches may include a set of ingress links and a set of egress links. One of the switches may store mapping information that identifies a first timeslot and one of the egress links for data received, during a second timeslot, on one of the ingress links. The one of the switches may receive data, associated with the second timeslot, on the one of the ingress links, identify the first timeslot and the one of the egress links, associated with the second timeslot and the one of the ingress links, based on the mapping information, and output the data, during the first timeslot, on the one of the egress links.
