`
`Low Speed Data
`
`Functional summary
`Technical Analyses, Generic Requirements, Traffic Engineering
`
`I led the Bellcore effort to test and analyze a number of ISDN data applications on #5ESS, DMS
`100F and Siemens EWSD. I also analyzed various network elements in X.25 packet networks
`including products from Siemens, NTI and BBN. Had prime responsibility for traffic, network
`management and performance sections of Bellcore’s Packet Switch Generic Requirements
`documents. I developed algorithms to design low speed packet networks, which resulted in
`prototype software. I developed a fundamental new methodology to service packet networks using
`simple measurements of burstiness.
`
`High Speed Data
`
`Data Traffic Characterization, ATM traffic engineering
`
`I headed the Bellcore effort to demonstrate inadequacy of current traffic models for engineering of
`high-speed data and other ATM applications. One of the main areas of application was Internet
`

`

`
`

`

`Intelligent Network
`
`Switch Analysis
`
`traffic engineering. Was responsible for developing alternative, fractal and self-similar, traffic
`models which can accurately predict effects of actual high-speed data traffic on system
`performance. I developed a world-leadership position in developing ATM traffic engineering
`methodologies.
`I proposed and modified several Bellcore generic requirements for local access
`technologies.
`Network Integrity Analysis
`
`I was Bellcore’s prime technical leader for determining root causes and proposing solutions in
`several SS7 outages including the 1990 ATT outage and the 1991 DSC STP outages. I had
`responsibility for the performance and robustness testing of several key Intelligent Network
`elements and their network management protocols. These included most of the SSPs and STPs
`used by the RBOCs and two SCPs.
`
`IN Requirements
`
`I was responsible for refining the performance requirements for Intelligent Network elements and
`end-to-end objectives. Part of this responsibility included the development of mathematical models
`of AIN performance. This resulted in identification of several problems in the existing SS7
`protocols and the performance impacts of a number of proposed solutions were quantified.
`
`PCS & IN Architectures
`
`I had responsibility for determining the impacts of various architectures on PCS (cellular)
`performance. This included the placement of AIN triggers in switch configurations, various PCS
`architectures and their performance characteristics, and the real time impacts of selecting protocol
`parameters for key AIN features such as automatic-call-back.
`
`Technical Analyses
`
`I analyzed (and tested) traffic engineering algorithms, traffic performance during normal and
`overload conditions, and the adequacy of traffic measurements for a number of voice switches.
`Special emphasis was put on real-time capacities of processors. These switches included: AT&T’s
`Nos. 1/1A, 2, 4 and 5 ESS; DCT, Dimension PBX and VMS; NTI’s DMS 100F including the
`SuperNode SE, DMS 200, TOPS and QMS; Siemens’ EWSD; Ericsson’s AXE; DSC’s Megahub;
`Rockwell’s DCD and parts of others. I was first to quantify effects of non-stationary and non-
`Poisson traffic on SPC switch performance.
`
`Switch Requirements
`
`Network Management, Capacity, Traffic, and Overload Requirements
`
`I was responsible for developing and maintaining several sections of Bellcore’s Local Switching
`Systems Generic Requirements (LSSGR) including sections on switch capacity estimation, traffic
`engineering, overload performance,
`traffic measurements and essential service protection. I
`invented the Last- In-First-Out (LIFO) overload strategy used in most modern switches in the US
`market and required by the LSSGR. I discovered the “traffic synchronization” effect, which can
`produce undesirable chaotic behavior in switches, and I developed an easily implementable
`solution. I was part of team that wrote the original requirements for the #5ESS.
`
`Operator Services
`
`Forcing and Facilities Algorithms
`
`I had prime responsibility for over 15 years for developing and maintaining all call center force
`staffing algorithms for the pre-divestiture AT&T and later for the Bell Operating Companies. I also
`had prime responsibility for facilities engineering issues (see above under Switch Analysis). I was
`
`3
`
`000003
`
`

`

`a key supporter of the economic introduction of new technologies into call centers. I am currently
`an algorithm specialist for ISC, a company who makes call center staffing software.
`
`Network Vulnerability
`
`Overload and Outage Analyses, Priority Traffic, Network Management
`
`I was prime technical contributor to National Emergency Telecommunications System (NETS)
`study that characterized the impacts of various network outage scenarios on local switch
`performance. Proposed priority algorithms and quantified their effects in mitigating service
`impacts on high-priority users.
`I was
`sponsored by the NSF to represent
`the US
`telecommunications industry at a joint US-Japan earthquake symposium. I analyzed the impacts of
`earthquakes on local exchange service.
`
`Voice Networks
`
`Traffic Forecasting, Private network analysis, Faulty trunk analysis, Video on
`Demand
`
`Voice Mail Systems
`
`Communication and Control
`Theory
`
`I pioneered the introduction of Kalman filtering techniques for traffic forecasting. Analyzed, and
`resolved, chronic trouble conditions in private networks which included both voice and data. I
`analyzed trunk termination problems in switching system, as well as network engineering and
`design. I pioneered the performance analysis of faulty telecommunications trunks having short, but
`ineffective, holding times. I analyzed several alternatives for providing video on demand services.
`Analysis of V-Mail Systems, traffic engineering, switch impact
`
`I analyzed (and tested) the traffic handling capabilities of several voice mail platforms and
`analyzed their engineering algorithms. I determined appropriate engineering loading levels for
`switch access. I determined switch capabilities and SMDI link limitations for various products.
`
`Aerospace Applications, Satellite Communications, Air Traffic Control
`
`I developed optimum algorithms for an infrared tracking system, and optimal detection of initial
`positions of dynamic objects. I determined optimum radar pulse allocation algorithm, and bounds
`on transmission rate performance through unknown channels. I analyzed the performance of
`UPCM coding system.
`I
`applied Kalman Filtering algorithms
`to predict
`traffic
`in
`telecommunications satellite application. I developed models and a validation methodology for air
`traffic control management system.
`
`Teaching
`
`University Courses, In-Hours Courses, Outside Short Courses
`
`I developed and taught advanced undergraduate courses in circuit theory, system theory and
`communications theory. I developed and taught graduate university courses in Teletraffic Models;
`one emphasizing theory for Ph.D. students,
`the other emphasizing applications for industry
`students. I developed and taught several in-hours courses at Bell Labs and Bellcore: Linear
`Discrete-Time Filtering Theory, Congestion Theory, Advanced Traffic Theory, Real Time
`Capacity Estimation and Computer Performance Analysis. I also developed and taught short (1-2
`day) courses for industry, including the FCC: Introduction to Traffic Engineering.
`
`Publications and Professional Activities
`
`I have contributed extensively to various journals and conferences. I was session chairman at
`variety of conferences. I have over 39 external publications and talks. I was a reviewer for several
`technical journals and conferences. I also was a large grant reviewer for the Australian Research
`Council.
