Lucent Technologies Inc. - Murray Hill NJ
International Classification:
G06F 15/173
US Classification:
709239, 709241
Abstract:
Systems and methods for provisioning QoS paths with restoration in a network. In one embodiment, one system includes: (1) a primary path generator configured to identify a suitable primary path between source and destination nodes in a network, (2) an auxiliary graph generator, associated with the primary path generator, configured to construct a directed auxiliary graph from an undirected graph representing the network by reversing each link in a primary QoS path of the undirected graph and replacing each other link in the undirected graph by two directed links, (3) a walk identifier, associated with the auxiliary graph generator, configured to identify a walk in the auxiliary directed graph corresponding to a set of bridges in the network and (4) a bridge identifier, associated with the walk identifier, configured to identify a set of bridges in the network such that at least one link of the primary path is protected by a bridge.

Seung-Jae Han - Basking Ridge NJ, US
Mark Anthony Shawn Smith - Jersey City NJ, US
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H04Q 7/00
H04Q 7/24
H04Q 7/20
US Classification:
370332, 370338, 455450
Abstract:
The adjacency of access points in a wireless, local area network is used to determine the existence of common overlapping access point coverage areas and to determine maximum distances between access points.

System And Method For Monitoring Link Delays And Faults In An Ip Network

View page
US Patent:
7472314, Dec 30, 2008
Filed:
Sep 26, 2003
Appl. No.:
10/672204
Inventors:
Yigal Bejerano - Springfield NJ, US
Rajeev Rastogi - New Providence NJ, US
Assignee:
Alcatel - Lucent USA Inc. - Murray Hill NJ
International Classification:
G06F 11/00
US Classification:
714 47, 714 4
Abstract:
A system for, and method of, monitoring link delays and faults in an IP network. In one embodiment, the system includes: (1) a monitoring station identifier that computes a set of monitoring stations that covers links in at least a portion of the network and (2) a probe message identifier, coupled to the monitoring station identifier, that computes a set of probe messages to be transmitted by at least ones of the set of monitoring stations such that the delays and faults can be determined.

Methods And Devices For Coordinating The Transmissions Of Access Points In Wlans

View page
US Patent:
7477610, Jan 13, 2009
Filed:
Mar 1, 2004
Appl. No.:
10/788458
Inventors:
Yigal Bejerano - Springfield NJ, US
Randeep S. Bhatia - Green Brook NJ, US
Assignee:
Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:
G01R 31/08
US Classification:
370252, 370458
Abstract:
The coordination of transmissions by access points (APs) in a wireless local area network (WLAN) is carried out by allowing APs to transmit during slots of a Contention Free Period (CFP). Prior to transmission, slots are assigned to APs using a 4-approximation technique. This technique allows an AP to transmit using multiple frequencies. The assignment of slots satisfies a maximal, lower bound of an AP slot-to-user ratio.

System And Method For Determining The Physical Topology Of A Network Having Multiple Subnets

View page
US Patent:
7535911, May 19, 2009
Filed:
May 27, 2003
Appl. No.:
10/445585
Inventors:
Yigal Bejerano - Springfield NJ, US
Yuri J. Breitbart - Silver Lake OH, US
Minos N. Garofalakis - Morristown NJ, US
Rajeev Rastogi - New Providence NJ, US
Assignee:
Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:
H04L 12/28
US Classification:
37039531, 370401, 370408
Abstract:
A system for, and method of, determining a physical topology of a network having multiple subnets. In one embodiment, the system includes: (1) a skeleton path initializer that uses addressing information from elements in the network to develop a collection of skeleton paths of direct physical connections between labeled ones of the elements, the skeleton paths traversing multiple of the subnets and (2) a skeleton path refiner, coupled to the skeleton path initializer, that refines the collection by inferring, from the direct physical connections and path constraints derived therefrom, other physical connections in the skeleton paths involving unlabeled ones of the elements.

Methods And Devices For Routing Traffic Using A Configurable Access Wireless Network

View page
US Patent:
7583602, Sep 1, 2009
Filed:
Jun 30, 2004
Appl. No.:
10/879064
Inventors:
Yigal Bejerano - Springfield NJ, US
Amit Kumar - New Delhi, IN
Assignee:
Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:
H04L 12/26
US Classification:
370238, 370913
Abstract:
A configurable access network (CAN) architecture is used to identify primary routing paths that allows each wireless station within a static, multi-hop wireless CAN to route packetized data in a way that simplifies the operation of each station and makes more efficient use of the limited energy available to each station.

View page
US Patent:
7606142, Oct 20, 2009
Filed:
Sep 30, 2004
Appl. No.:
10/955265
Inventors:
Yigal Bejerano - Springfield NJ, US
Joseph Seffi Naor - Haifa, IL
Alexander Sprintson - Pasadena CA, US
Assignee:
Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:
H04L 12/26
US Classification:
370217, 370228, 370252
Abstract:
A method comprises allocating a respective restoration path to protect each of a plurality of primary paths in a network. Each primary path has a plurality of nodes and at least two subpaths connecting the nodes of the primary path. Each restoration path includes at least one link. Each link protects at least one of the subpaths of the primary path. Each of the subpaths of the primary path is protected. None of the links in the restoration path is included in the corresponding primary path. At least one of the links is shared among at least two restoration paths corresponding to at least two of the primary paths.

Fairness And Load Balancing In Wireless Lans Using Association Control

View page
US Patent:
7836181, Nov 16, 2010
Filed:
Aug 17, 2005
Appl. No.:
11/205768
Inventors:
Yigal Bejerano - Springfield NJ, US
Seung-Jae Han - Basking Ridge NJ, US
Li Li - Iselin NJ, US
Assignee:
Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:
G06F 15/173
US Classification:
709226
Abstract:
Association control is utilized for associating wireless local area network users with at least one wireless local area network access point and thereby achieving simultaneous fairness and load balancing. In the present method, a network operation center receives user parameters from each user in the wireless network via the access points. It then sets out both to determine a set of associations between each user and one or more access points based on the user parameters using fractional load balancing and produce a second set of associations by rounding so that, in said second set, each user is associated with only one access point. The present method achieves close to optimal load balancing and max-min fairness while outperforming commonly-used heuristic approaches.
