  • 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

  • Dual-homing select architecture
    Patent number: 6662308
    Abstract: A network architecture comprised of nodes and a transport network capable of recovering from failures within the network. The network architecture incorporates select functions into the nodes for managing the data flow between individual edge routers and their connection through core routers to the transport network. The select function allows an individual node to recover independently without signaling other nodes over the transport network. Utilizing the select function, the failure of a single core router can be recovered locally without recovery signaling over the transport network.
