  • Optical transmission systems, devices, and methods
    Patent number: 7986881
    Abstract: Optical communications systems including grooming, protection, restoration, and migration on a unified network platform, and using a unified control plane. The systems may include combinations of optical bypass and mesh restoration, may include combinations of shared mesh and dedicate protection, and may be combinations of long haul, extended long haul, and ultra long haul systems. The systems may also include a configurable DWDM tier to accommodate dynamic traffic patterns, thereby allowing for increased operational flexibility.
    Type: Grant
    Filed: October 19, 2009
    Date of Patent: July 26, 2011
    Assignee: Level 3 Communications, LLC
    Inventors: Jonathan L. Weston-Dawkes, Stefano Baroni, Marian Trnkus, Lotfi M. Benmohamed, Jean-Luc Ronarc'h

  • Systems, devices, and methods utilizing port dimensioning strategies
    Patent number: 7542420
    Abstract: Methods, systems, and devices utilizing port dimensioning strategies for supporting, for example, bandwidth-on-demand (“BoD”) services in networks. At a given node, the traffic load consists of several components, such as an access component, which is generated by demands terminated at that node, and a transit component, which is generated by demands that transit electronically through the node. Given the BoD load at a node, as well as a target BoD average blocking probability, a desired static allocation of the ports is provided between ports of a first type (such as client-side ports) and ports of a second type (such as network-side ports). In addition, a dynamic sharing strategy of the ports is also disclosed.

  • Connection admission control for bursty real-time traffic in a network with multiple service classes
    Patent number: 7542416
    Abstract: The method estimates a capacity requirement as a function of a cell loss ratio (CLR) requirement, estimates a capacity requirement as a function of the a cell delay variation (CDV) requirement, and sets the capacity requirement based on these independent estimates. The capacity requirement is then used to determine connection admission control in the network.
