As Chief Scientist, Dave Belanger is responsible for identifying pre-product technology important to the future of AT&T, evaluating technology, building alignment within AT&T on technology directions, and serving as AT&T liaison to external technical communities, specifically universities, government agencies, and industry laboratories.
His particular focus is in leading research in large-scale and real-time information mining related to operations of a (communications) service business; interactive, information visualization; scalable, reliable software systems; and new, information-based, communications services. It is also responsible for delivery and operations of very large-scale (e.g. >300TB), near real-time service management capabilities to AT&T and its customers. Dave joined AT&T Bell Laboratories in 1979 working in the area of database support for economic analysis for product lifecycles, later researching large-scale data and information systems, and program generation for data manipulation systems. He has subsequently led research efforts in software systems and engineering, and information mining, and visualization.
Prior to joining AT&T, Dave was on the Mathematics and Computer Science Faculty at University of South Alabama, a consultant for a variety of companies, and co-founder/VP of Gulf Coast Data Systems (a computing services company). He received his B.S. from Union College (NY) in Mathematics, and an M.S. and Ph.D., also in Mathematics, from Case Western Reserve University.
Dave was named AT&T Fellow in 2006 honored for a lifetime of outstanding and world-class contributions in the fields of software tools, software systems and information mining. In 2009, Dave received the IEEE Communications Society Industrial Innovation Award for pioneering, innovating, and leading the interdisciplinary execution of information systems that transform massive online data streams into actionable information for servcie businesses.
Method And Apparatus for Designing Radio Access Networks Including Broadband Wireless Links,
Tue Apr 19 16:02:03 EDT 2011
A technique for reducing costs associated with a radio access network of a mobile telecommunications network includes configuring the radio access network using a linear programming model of the radio access network subject to constraints. The technique includes selecting cellular sites and hub locations of the radio access network to be connected by broadband wireless links based on the linear programming model and constraints. In at least one embodiment of the invention, a method of designing a radio access network of links between a cellular site and a core network includes selecting at least one first link of the radio access network to be at least one first wireless link at least partially based on a linear programming model of the radio access network. The method includes configuring an output device of a computer system to indicate the selection.
Arrangement For Guiding User Design Of Comprehensive Product Solution Using On-The-Fly Data Validation,
Tue Mar 30 15:50:24 EDT 2010
A computer-implemented method guides a user in designing a product defined by data. The method involves examining (420) items of the data to detect whether each item conforms to rules (106) or violates the rules; performing (431 . . . ) at least one action in response to a detection of a rule violation; displaying (450) the data to the user in a manner emphasizing at least one particular data item that caused the rule violation; receiving (460) any new data input from the user; and repeating the examining, action performing, and displaying steps using the new data. The displaying step may involve displaying data defining a current state of the product in a tabular (spreadsheet) format, including displaying data detected to have caused the rule violation in a first manner that is visibly distinct from displaying other data that is not detected to have caused the rule violation.
Method And Apparatus For Evaluating Optimal Access Providers For Long-Haul Communication Providers,
Tue Oct 27 15:38:49 EDT 2009
A method and an apparatus to automate the process and procedure for long haul service providers to choose the best quote from a pool of quotes or RFP responses as the best supplier in a country or region. The disclosed method and apparatus includes a mathematical framework which determines the characteristics of each supplier option and a method to determine the cost effectiveness of each option. This method and apparatus reduces overhead and improves the evaluation process for choosing optimal access providers for long-haul communication providers.
Method for reducing congestion in packet-switched networks,
Tue Jun 05 18:12:04 EDT 2007
The present invention permits a network service provider to detect an operational condition--such as congestion--in a packet-switched network and to alleviate such congestion by providing customer incentives to avoid use of the network. The detection mechanism triggers an incentive such as the modification of the user's access charges and the customer can be immediately notified of either the occurrence of the congestion or of information regarding the incentive. Usage of the network during congested periods can be deterred by imposing additional access charges during such periods--similarly, customers can be given a discount to encourage usage during periods of low congestion. An incentive schedule can be tailored to dynamically change the usage patterns of the customers of the network to accommodate the operational conditions in the network. The present invention has application in the Internet, where a detection/notification mechanism, for example, can be implemented in a network node such as a router or in a network endpoint such as a client machine or a proxy or mail server.
