  • Patent number: 7274702
    Abstract: The invention provides a chassis, a scalable router that includes a plurality of chassis and a method of upgrading a router. Each chassis includes a plurality of processing modules and a programmable interconnection module. Data connections are provided between each processing module on each chassis and the interconnection module on that chassis, and a data connection is provided between the interconnection module on each chassis and the interconnection module on at least one other chassis. In this way, the inter-chassis and intra-chassis connections pass through the programmable interconnection module, which may be used for concentrating the location of resources, such as opto-electronic and electro-optical converters, in a single card or unit. Moreover, the programmable nature of the switch fabric in each interconnection module is amenable to reconfiguration so as to support a change in that chassis' interconnection pattern that may be required for expanding the router's capacity.

  • Patent number: 6311067
    Abstract: Utilizing a sequential local search optimization algorithm, a determination is made of the cell/transceiver retunes needed to implement, given a current frequency plan, a better frequency plan for a certain cellular communications system. Each of the individual cell/transceiver retunes is evaluated to determine if it meets certain save criteria, and if so, is saved as an intermediate frequency plan in a sequence of saved intermediate frequency plans necessary to migrate from the current frequency plan to the determined near-optimal frequency plan. A sequential implementation of these intermediate frequency plan revisions is then made to gradually reach, in a known and controlled manner, the better frequency plan.
