Patent number: 8774627Abstract: The design of telecommunication networks is such that there is provision of end-to-end path protection to multiple demands under a single link or node failure in the networks. Restoration routes are provided on Preconfigured Virtual Cycles (PVC's), where each demand is assigned one restoration route and specific restoration wavelengths on a segment of one cycle. Multiple demands may share restoration wavelengths, and the number of restoration wavelengths may vary among the PVC links. First, a plurality of candidate PVC's are generated where each demand may be assigned to multiple candidates. Assignment of demands with common failure scenarios are allowed, under certain conditions, to the same PVC. Next, a set of PVC's is selected from among the candidates, while minimizing total reserved restoration capacity and ensuring that all demands are protected. Next duplicate assignments are eliminated. Finally, conflicts of wavelength assignments are resolved. The invention focuses primarily on optical networks.Type: GrantFiled: August 16, 2012Date of Patent: July 8, 2014Assignee: Telcordia Technologies, Inc.Inventors: Hanan Luss, Martin Eiger, David Shallcross

Patent number: 7463892Abstract: Traffic flows of data packets from respective packet queues in wireless stations to a shared transmission medium of a wireless network are scheduled in accordance with Hybrid Controlled Channel Access (HCCA) and Enhanced Distributed Channel Access (EDCA). HCCA is applied by eliminating from consideration for HCCA access flows for which the sum of a desired minimum age of an oldest data packet in the respective packet queue and the time of creation of the oldest data packet is greater than the present time. For flows that are not eliminated from consideration, HCCA access is granted to the flow having a smallest sum of the desired maximum age of the oldest data packet and the time of creation of the oldest data packet. When all traffic flows are eliminated from consideration for HCCA access, EDCA is applied so that traffic flows compete for access to the medium.Type: GrantFiled: August 12, 2005Date of Patent: December 9, 2008Assignees: Toshiba America Research, Inc., Telcordia Research Associates Inc.Inventors: Martin Eiger, Moncef Elaoud, Raquel Morera

Patent number: 7082401Abstract: A method for placing equipment in a network begins with a baseline network on which demographic data is analyzed statistically to produce a demographically-driven driven demand forecast model. The demand forecast model yields a predicted demand for each census block group. This can be visualized as one map layer with a GIS. The layout method takes the predicted demands as input and produces new attribute information for network nodes, the central office and cross-connects. By the layout method the cost of placing equipment at available placement sites or nodes is minimized based on various constraints, e.g., the capacity of the equipment to be placed, the distance a user is located from a potential node. Once the minimum cost for a given set of placement sites, subscribers, equipment capacity, and other known constraints is determined the equipment are then placed at these sites. These include the number and type of DSLAMs assigned to each node.Type: GrantFiled: March 23, 2001Date of Patent: July 25, 2006Assignee: Telcordia Technologies, Inc.Inventors: Clifford Allen Behrens, Tamra Carpenter, Martin Eiger, Hanan Luss, George Seymour, Paul Seymour
