摘要： An optical modulator provides for preceding of a high data rate phase modulated optical signal. According to one embodiment, the modulator includes a first phase modulator and a second phase modulator. The first phase modulator modulates an optical carrier signal according to a first data signal to generate a modulated optical signal. The second phase modulator modulates the modulated optical signal according to a time delayed version of its optical output signal. According to another embodiment, the modulator electrically precodes multiple data streams and modulates the precoded data streams using a series of phase modulators to generate a precoded optical data signal.

摘要： A system of route target filtering includes an import filter receiving a plurality of routes having a next hop routing information. The import filter accepts a first subset of the routes according to an import target policy. The system further includes a re-export filter also receiving the plurality of routes. The re-export filter modifies the next hop information of a second subset of the routes, and distributes the modified routes.

摘要： An advanced SONET add/drop multiplexer capable of supporting packet over SONET and multiprotocol label switching. The add/drop multiplexer is capable of adding and/or dropping both STM and packet traffic, such as Internet Protocol traffic. This SONET add/drop multiplexer allows Internet Protocol streams which are added or dropped at different nodes to be carried over the same SONET path in a network, thereby greatly saving bandwidth.

摘要： An element management system in which: a list of fully-qualified versions of network elements is maintained, and the interface to each network element is managed in accordance with the highest fully-qualified version which is no later than the network element's actual version date, EVEN IF there is also a fully-qualified later version. By specifying a nullmanaged levelnull which is fully qualified and is guaranteed not to be later than the actual revision of the network element, the possibility of hidden incompatibility is reduced. (Network elements are expected to be backwards compatible, but the addition of features may introduce some hidden forward incompatibility.)

摘要： A network router generates node state advertisements identifying network links about which the router node desires to receive link state information. The node state advertisements are flooded to other routers, each of which determines whether it lies along the shortest path between the link and the originating router. Each router that lies along the shortest path maintains an association between the link and the originating router, the association indicating that link state advertisements concerning the link are to be forwarded along the path toward the originating router. Upon a change of the state of the link, each router forwards a corresponding link state advertisement to an adjacent node along the path, whereby the originating router ultimately receives the link-state advertisement.

摘要： A system and method of protection switching in a communications network that makes more efficient use of resources in the network and reduces the loss of data traffic carried by the network. The communications network includes an established working path and an established protect path interconnecting a source node and a sink node. The source node and the sink node are configured to perform label switching on the network. The source node receives primary data traffic and secondary data traffic over one or more communications paths. In a fault-free condition, the source node sends the primary data traffic over the working path to the sink node, and sends the secondary data traffic over the protect path to the sink node. In the event of a fault or switchover condition in the working path, the source node performs traffic trunk and label merging on the primary and secondary traffic, and sends the merged traffic over the protect path to the sink node.
