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. Fisher, David W. Jenkins

Patent number: 8942558Abstract: Due to demand for more network bandwidth, a need for multi-user optical network topologies has, and will continue to, increase. A method or corresponding apparatus in embodiments of the present invention provide for an availability determination tool for determining and displaying wavelength and subrate availabilities within a network. Benefits of embodiments of a tool include allowing a user to identify the availability and capacity of any wavelength on any network, via an interactive graphical user interface, such as by using three-dimensional representations. In one embodiment, the disclosed availability determination tool allows users to locate and view any combination of available wavelengths between nodes in an optical network topology, and generate graphical and tabular reports of the availability in order to maintain an efficient and organized method or apparatus for determining and controlling wavelengths in a network.Type: GrantFiled: May 15, 2013Date of Patent: January 27, 2015Assignee: Tellabs Operations, Inc.Inventors: David W. Jenkins, Ramasubramanian Anand, Hector Ayala, Dion Kwun Kit Leung, Kenneth M. Fisher

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.

Patent number: 8321547Abstract: A method for planning a multi-phase network includes storing initial parameter values for parameters associated with first and second growth phases in a multi-phase network plan, wherein each of the first and second growth phases is characterized by sets of the parameters. The method also includes calculating an initial growth scenario including the first and second growth phases based on the initial parameter values, and adjusting a value for at least one of the parameters to produce a modified parameter value. The method further includes automatically calculating a new growth scenario based on the modified parameter value and at least a portion of the initial parameter values, and displaying the new growth scenario. A computer readable medium for implementing the method described herein is also provided.Type: GrantFiled: May 22, 2008Date of Patent: November 27, 2012Assignee: Tellabs Operations, Inc.Inventors: Ramasubramanian Anand, Hector Ayala, Abhishek J.

Patent number: 8078435Abstract: Optical regeneration is expensive to implement and maintain. A method or corresponding apparatus in an example embodiment of the present invention enables a user to plan an optical regeneration in a network with a reduction of optical regeneration compared to unplanned deployment. An optical regeneration planning tool according to an example embodiment of the present invention can graphically display a representation of a network topology with optical regeneration sites and enable the user to plan optical regenerations at a subset of the sites as a function of characteristics of models of optical network elements and paths within the network topology. Through use of the optical regeneration planning tool, a service provider can save on network deployment and future servicing of optical regeneration equipment.Type: GrantFiled: August 15, 2008Date of Patent: December 13, 2011Assignee: Tellabs Operations, Inc.Inventors: David W.

Publication number: 20100287403Abstract: Fault management and providing resilience against failures is an useful for many networks. Protection techniques are used to ensure that networks can continue to provide reliable service and to provide redundant capacity within a network to reroute traffic in presence of a failure. A method or corresponding apparatus according to an example embodiment of the present invention relates to determining availability in a network. The example embodiment calculates availability on a per demand basis for working, protection, and restoration paths among all demands in the network and reports the availability. The reported availability may be used to plan and suggest changes to the network or to recommend addition of equipment to improve the availability of the network while ensuring that service level agreements are satisfied.Type: ApplicationFiled: May 6, 2009Publication date: November 11, 2010Applicant: Tellabs Operations, Inc.Inventors: David W.
