| 7958209 | Methods and systems to generate and implement a changeover sequence to reconfigure a connection-oriented network A method to reconfigure a connection-oriented network from an existing configuration to a desired configuration includes generating a sequence of configuration specifications for the connection-oriented network. The sequence specifies a plurality of intermediate con... | 06/07/2011 |
| 7782773 | Metric optimization for traffic engineering in a metric-routed network A method is performed to optimize metrics associated with links of a network that is routed utilizing a shortest-path-first (SPF) routing method. The method includes identifying at least one failure scenario applicable to the network and identifying at least one ban... | 08/24/2010 |
| 7734813 | Method and system for communicating predicted network behavior between interconnected networks A method of communicating predicted network behavior includes generating network topology structure data describing at least part of a topology of a first network. Demand structure data is generated, the demand structure data describing at least some traffic demands... | 06/08/2010 |
| 7505413 | Methods and systems to perform traffic engineering in a metric-routed network A system, to migrate a shortest-path-first (SPF) routed network from a first routing state to a second routing state, includes a changeover module to generate a sequence of intermediate network plans, each of which modifies a preceding network state according to a p... | 03/17/2009 |
