Patent number: 10826818Abstract: Switches within a telecommunications network exchange so-called available bandwidth messages, each of which advertises how much bandwidth remains unassigned on a respective link. The network is of a type in which circuits are provisioned with various predefined numbers of time slots (equivalent to bandwidth). The sending of an available bandwidth message for a given link is triggered by a change in the number of time slots available on that link if that change results in a change in the number of circuit bandwidths that can be accommodated by that link for a newly provisioned circuit.Type: GrantFiled: February 2, 2018Date of Patent: November 3, 2020Assignee: AT&T Intellectual Property II, L.P.Inventors: Bruce Gilbert Cortez, Sanja Durinovic-Johri, Pravin Kumar Johri, John Paggi, Simon S.

Patent number: 7848642Abstract: A method and system provide capacity-efficient restoration within an optical fiber communication system. The system includes a plurality of nodes each interconnected by optical fibers. Each optical fiber connection between nodes includes at least three channel groups with different priority levels for restoration switching in response to a connection failure. The system maintains and restores full-capacity communication services by switching at least a portion of the channel groups from a first optical fiber connection to a second optical fiber connection system based on the priority levels assigned to the channel groups. Service reliability is effectively maintained without to incurring additional costs for dedicated spare optical fiber equipment by improving idle capacity utilization.Type: GrantFiled: January 30, 2008Date of Patent: December 7, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Sid Chaudhuri, Bruce Gilbert Cortez, Simon S.

Patent number: 7570886Abstract: A network arrangement where traffic elements of network nodes are programmable. A traffic element comprises electrically controllable transceiver pool having one or more ports that are coupled to an electrically controllable optical director that has all-optical information communication paths. The transceiver pool has one or more customer connection points in addition to the one or more connection points that connect to the optical director, and is adapted to couple a signal from any of the customer connection points to the optical director, at a particular wavelength. The choices for the specific coupling within the optical director and of the wavelengths are specified by control signals that are applied to the transceiver pool and to the optical director.Type: GrantFiled: March 11, 2004Date of Patent: August 4, 2009Inventors: Thomas S.
