DATA COMMUNICATIONS

(selected excerpts)

Developed a set of alternative designs for a shipboard radio trunking network for the U.S.S. Eisenhower that will become the model for the next generation carrier network, and the U.S.S. Ponce that will become the model for the next generation amphib network. The networks are based on radiating transmission line (RTL) cable.

Completed the design and installation of a fiber-optic/AUI LAN for SUBLANT. The LAN serves several work groups located over two different floors of the building, and includes a file server containing the technical maintenance database presently used by SUBLANT, a communications server providing support for a modem pool used for outside communications, and a print server.

Teach graduate courses in data communications and networking at Old Dominion University. These courses include networking over both guided media and radio/microwave applications. Designed local area networks (LANs) and interfaces for several of the laboratories.

Developed the networking design and requirements for the U.S. Army Computer-aided Acquisition and Logistics Support (CALS) system. This system consisted of IBM mainframes, DEC VAX minicomputers, AT&T communications processors, IBM compatible PCs, Apple Macintoshes, Sun workstations, and Intergraph CAD/CAM workstations, connected by Ethernet subnetworks and Token-ring subnetworks with a high-speed fiber optic network backbone.

Led a team that designed a smart building system for an office building in Dayton, Ohio. The multifunctional backbone was designed along with the subsystem interfaces. The system was designed to handle multiple local area network (LAN) communities, terminal-to-host communications, security badge readers, video, and an energy monitoring and control system for the building.

Was the head of a team that designed a local area network for Charleston Naval Shipyard that would link over 1500 stations in over 100 buildings with computer equipment made by a variety of vendors. The network spans an area of approximately 1 square miles and uses over 100 bidirectional amplifiers and 10 miles of broadband coaxial cable. A redundant fiber optic backbone was provided for future expansion. The system was designed to provide not only links to different computer systems, but also incorporate teleconferencing, video surveillance, secure digital telephone, bar code and security badge readers, and external interfaces to such networks as the Defense Data Network (DDN).

Developed MIL-STD 188-256 for digital signaling and supervision in tactical communications systems. This involved reviewing existing Joint Tactical Communications (TRI-TAC) Office specifications, communications systems specifications, and communications procedures to determine areas to be included in the MIL-STD and appropriate performance criteria to be required of tactical communication systems in the area of digital signaling and supervision.

Developed the U.S. Army standard and the protocol specification for Digital Variable Message Formats (VMF) for U.S. Army Center for System Engineering and Integration (CENSEI) while at BDM. Subsequently performed analysis of applications of VMF to TADIL A, TADIL B, TADIL C, TADIL J, SHORAD, and the PJH-CCS2 interfaces.

Participated in the development of several NATO Standardization Agreements (STANAGs). These STANAGs specified the data communications protocols for functions in Layers I, II, and III as delineated by the ISO OSI model.

Led a team in the development of the Army Command and Control System (ACCS) Protocol Reference Model. This task utilized the ISO OSI seven-layer reference model as a baseline and made changes to that baseline to meet peculiar military requirements and to resolve inconsistencies in the OSI model. Assisted in the development of interface specifications for the Army CCS2 control elements. These specifications covered the electrical, procedural, and format requirements for information transfer between two CCS2 control elements.
