Patent number: 9112789Abstract: When planning and maintaining a network, it may be very difficult for a network provider to organize variations of equipment rack installations at several different sites. Present methods of planning installation configurations in a network involve planning the same equipment installation configuration at all sites, planning a limited number of variations, or planning multiple variations but, with difficulty, tracking and changing configurations. A method or corresponding apparatus in an example embodiment of the present invention provides a tool for simplifying the planning of multiple network element installation configurations at multiple sites within a network. The benefits include fewer required truck rolls, resulting in reduced costs before and after deployment of installation configurations.Type: GrantFiled: August 15, 2008Date of Patent: August 18, 2015Assignee: Tellabs Operations, Inc.Inventors: Ramasubramanian Anand, Hector Ayala, Kenneth M.

Patent number: 8712237Abstract: Signals propagating in wavelength division multiplexing (WDM) optical networks suffer from loss, which decreases optical signal-to-noise ratios (OSNRs) and degrades a quality of received transmissions. Present methods of boosting OSNRs involve regeneration using transponders, which scale in complexity with the number of WDM channels. Optical amplifiers may boost signal strength, but amplified spontaneous emission (ASE) noise often reduces OSNR despite increases in signal strength, although changing the amplifier operating settings may reduce emitted ASE noise power. A method or corresponding apparatus in an example embodiment of the present invention provides a planning tool for deploying optical amplifiers in an optical network in a manner that reduces the need for optical regeneration, reducing cost and complexity of the deployed network.Type: GrantFiled: August 15, 2008Date of Patent: April 29, 2014Assignee: Tellabs Operations, Inc.Inventors: David W.

Publication number: 20140093231Abstract: A procedure for recovering a communication network, and a system, apparatus, and computer program that operate in accordance with the procedure. The procedure comprises aggregating network related information. A determination is made, based on the network related information, of whether one or more predetermined failure thresholds have been exceeded, to generate a determining result. The one or more predetermined failure thresholds are based, at least in part, on an aggregation of a predetermined number of failures. A re-provisioning algorithm is executed to re-provision one or more portions of the communication network based on at least one of the network related information and the determining result.Type: ApplicationFiled: October 2, 2012Publication date: April 3, 2014Inventors: KENNETH MARTIN FISHER, DAVID W.

Publication number: 20130272697Abstract: Increasing data rates in next-generation optical networks requires a change in the type of optical modulation used to encode optical signals carried by the optical networks. Different types of optical modulation incur different optical impairments, which may degrade the fidelity of the optical signals by reducing the optical signal-to-noise ratio (OSNR). A method or corresponding apparatus in an example embodiment of the present invention provides a planning tool for deploying an optical network in a manner based on the optical modulation that reduces the cost and complexity of the deployed network. In one embodiment, the disclosed planning tool may adjust a model of the optical network to be deployed by changing the topology and/or the number and/or type of optical network elements in response to optical impairments for a given optical modulation.Type: ApplicationFiled: June 10, 2013Publication date: October 17, 2013Inventors: David W.
