Patent number: 10616074Abstract: A procedure for evaluating a network, and a system, apparatus, and computer program that operate in accordance with the procedure. The procedure includes aggregating packet information from one or more sources in a network, and executing a correlation algorithm to determine traffic flow information based on the packet information. The aggregating includes obtaining information from a header of a packet being communicated in the network, in one example embodiment. In another example, the executing includes tracing a traffic flow from a source node to a destination node, and the tracing includes determining, based on the packet information, each link by which the traffic flow is communicated from the source node to the destination node.Type: GrantFiled: October 6, 2017Date of Patent: April 7, 2020Assignee: Coriant Operations, Inc.Inventors: David W.

Patent number: 10469193Abstract: Method and apparatus of a network configuration configured to permit a dense wavelength division multiplexing (“DWDM”) element to connect to a storage server, an Internet Protocol (“IP”) router, and DWDM network are disclosed. The configuration includes the DWDM network, storage area network (“SAN”) server, IP router, and optical transport network (“OTN”) switch. While the DWDM network transports information via optical fibers, the DWDM switch is coupled to the DWDM network for transporting optical signals. The SAN server is coupled to a port of the DWDM switch and is configured to store data at a remote location. The IP router which is coupled to the DWDM switch facilitates IP traffic between a user and the DWDM network. The OTN switch, coupled to the first DWDM switch, is capable of processing at least a portion of the optical signals.Type: GrantFiled: October 19, 2018Date of Patent: November 5, 2019Assignee: Tellabs Operations, Inc.Inventors: David Jenkins, Ramasubramanian Anand, Joel Butz

Patent number: 9252904Abstract: The disclosed methods and apparatuses provide a unique and cost efficient approach to using traffic channels of an optical mesh network, and sometimes optical supervisory channels, for carrying timing information (e.g., BITS timing signals), thus eliminating the need to use external BITS sources at remote add/drop nodes of a network. Planning the distribution of timing in such an optical mesh network includes identifying in the network a source node associated with an external timing source, identifying optical light paths between nodes in the network, and, for nodes other than the source node, selecting optical light paths originating either directly or indirectly from the source node to use to derive timing information.Type: GrantFiled: June 1, 2011Date of Patent: February 2, 2016Assignee: Coriant Operations, Inc.Inventors: Abhijit S.

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: 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.

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.
