Optimal Allocation Of Multi-Service Concentrators

View page
US Patent:
6760310, Jul 6, 2004
Filed:
May 20, 1999
Appl. No.:
09/315271
Inventors:
Lev B. Sofman - Plano TX
Assignee:
WorldCom, Inc. - Ashburn VA
International Classification:
H04L 1226
US Classification:
370238, 370252
Abstract:
This is a system and method for optimally allocating multi-service traffic concentrators in telecommunications network. A problem model representing the telecommunications network topology is formulated and input to a linear programming algorithm for an optimal solution. In the model, data set indices are defined as those components and/or factors in the telecommunications network which affect various operations of the network, and include origination, concentration, and destination sites as well as different multiplexer levels at each of the sites. Decision variables representing measure of efficiency in the network and whose optimal values are to be computed by the linear program are defined to include concentrator node selection, concentrator to destination site connection status, and the number of optical carrier trunks for each concentrator. The values for each of the three variables provide the equipment quantity for optimally allocating multi-service traffic concentrators. The objective function to be minimized is defined as minimum of the sum of total transmission cost between selected origination sites and selected concentration sites, total transmission cost between selected concentration sites and selected destination sites, total unit cost of concentrators, total port cost on the low side of the concentrators, and total optical carrier level port cost on the high side of the concentrators and the destination switches.

Alien Wavelength Channel Balancing And Line Amplifier Optimization

View page
US Patent:
8055129, Nov 8, 2011
Filed:
May 7, 2008
Appl. No.:
12/116480
Inventors:
David Butler - Richardson TX, US
Lev B. Sofman - Allen TX, US
Assignee:
Alcatel Lucent - Paris
International Classification:
H04B 10/00
H04B 10/08
H04J 14/02
US Classification:
398 33, 398 37, 398 38, 398 94, 398160
Abstract:
An algorithm is disclosed for performing alien-wavelength channel balancing on channels between optical network elements within an optic-fiber communications system. The algorithm determines initial values of various optimization parameters for each of the channels, such as the input launch power and operating conditions of optical amplifiers in the optical path, and calculates an initial total optimization offset for the channels based on the initial values of the optimization parameters for each of the channels. The algorithm then adjusts the optimization parameters to new values and calculates a new total optimization offset based on the new optimization parameter values. The algorithm repeats this process until the relative channel launch powers and optical amplifiers are optimized.

System And Method For Determining Cache Memory Size At A Network Node Of An Iptv Network

View page
US Patent:
8201206, Jun 12, 2012
Filed:
Jul 31, 2009
Appl. No.:
12/533027
Inventors:
Lev B Sofman - Allen TX, US
Bill Krogfoss - Frisco TX, US
Assignee:
Alcatel Lucent - Paris
International Classification:
H04N 7/173
US Classification:
725 94, 725109, 711112
Abstract:
In an IPTV network, cache memory assigned to each DSLAM, Central Office (CO) or Intermediate Office (IO) can be determined by defining a network cost function having cache memory per DSLAM, cache memory per CO and cache memory per IO as decision variables. The network cost function can be minimized to determine the optimal cache memory size for the network. The network cost function can be subject to boundary constraints that the cache memory is between zero and a maximum cache memory size for each network node type, allowing the network cost function to be solved as a 3-ary tree.

System And Method For Determining A Cache Arrangement

View page
US Patent:
8464303, Jun 11, 2013
Filed:
Sep 18, 2008
Appl. No.:
12/284079
Inventors:
Lev B. Sofman - Allen TX, US
Bill Krogfoss - Frisco TX, US
Anshul Agrawal - Plano TX, US
Assignee:
Alcatel Lucent - Paris
International Classification:
H04N 7/173
US Classification:
725115, 725 92, 725145
Abstract:
In an IPTV network, one or more caches may be provided at the network nodes for storing video content in order to reduce bandwidth requirements. Video content titles may be stored in the cache in accordance with a calculated cache arrangement that minimizes the total incremental transport cost of the content traffic.

Access Node Capable Of Dynamic Channel Caching

View page
US Patent:
8510787, Aug 13, 2013
Filed:
Dec 19, 2005
Appl. No.:
11/311081
Inventors:
Anshul Agrawal - Plano TX, US
Bill Krogfoss - Frisco TX, US
Lev Sofman - Plano TX, US
Assignee:
Alcatel Lucent - Paris
International Classification:
H04N 7/173
US Classification:
725127, 725 91, 725 92, 725 93, 725 95, 725119
Abstract:
An access node (e. g. , DSLAM) is described herein which can limit bandwidth usage in a transport network by incorporating an enhanced rapid TV channel changing functionality/enhanced BTV server in which TV channels from a multicast TV stream are dynamically selected based on past TV channel clicking statistics and then stored therein so there is a good chance that it can respond to a TV channel change request from a STB.

Method And System For Automated Voice Quality Statistics Gathering

Lev Sofman - Plano TX, US
International Classification:
H04L001/00
US Classification:
370/229000, 370/252000
Abstract:
A method of monitoring the quality of a communication system is described. A first telephone user initiates a telephone call with a second telephone user. The service provider connects the first telephone user with the second telephone user so that the telephone conversation can be conducted.

Intrusion Detection In Optical Fiber Networks

View page
US Patent:
20080018884, Jan 24, 2008
Filed:
Jan 18, 2007
Appl. No.:
11/624330
Inventors:
David Butler - Richarson TX, US
Scott Thompson - Lucas TX, US
Lev Sofman - Allen TX, US
International Classification:
G01N 21/00
US Classification:
356073100
Abstract:
A method for intrusion detection in an optical fiber communication network. The method includes at a first location on an optical fiber segment, receiving a set of multiple optical signals having wavelengths differing from each other, measuring received signal power for each of the received multiple optical signals, and repeating the receiving and the measuring steps. Each optical signal in the repeated steps has same wavelength as corresponding received optical signal in the initial steps. The method further includes computing a signal power loss between each received optical signal in the repeated set and the corresponding optical signal in the initial set, fitting a curve of signal power loss vs. wavelength to the computed signal power losses using a statistical analysis, and if the signal power loss of the curve over a preselected wavelength band is at least as great as a preselected minimum loss level, providing intrusion notification.
