Analysis of Integrated and Nonintegrated Voice and Data Networks for DoD Communications


Book Description

The primary question to be addressed in this thesis is, What is the best switching approach, with or without voice and data integration, that will maximize mission essential needs of DOD communications? This question can be answered by modeling integrated voice and data networks and separate voice and data networks. Included in this modeling will be the analysis of different switching techniques to determine the best switching approach. Mathematical analysis results are used to verify a simulation model. This simulation model is used to analyze different possibilities of meeting DOD requirements. These DOD requirements and performance criteria for switching are defined and presented in Chapter II. Specific conditions are set to insure performance changes are based on the switching techniques, and the percentages of voice and data in a system. The approach taken in this research was to use analytical techniques and to develop a simulation model for analyzing different voice and data integrated and nonintegrated environments.







Economic Analysis of Integrated DOD Voice and Data Networks


Book Description

Alternative switching strategies for future integrated DOD voice and data networks are studied. Three fundamental problems are addressed: (1) The economics of integrating voice and data applications in a common communication system; (2) the comparison of alternative switching technologies for integrated voice and data networks; (3) the economics of low voice digitization rate devices. Strategies examined are traditional, fast, and ideal circuit switching, hybrid (circuit-packet) switching, and packet switching. These strategies are examined in conjunction with a data base representing future Defense Department voice and data requirements. The major conclusion is that packet switching is substantially more cost-effective for serving these voice or data requirements than the other alternatives examined. The sensitivity of the results are tested with respect to traffic variations, cost trends of switching and transmission, and network performance variables. The significant variables which affect the conclusions are identified and quantified. (Author).







Integrating Voice and Data Networks


Book Description

Annotation Voice/Data Integration on Cisco Networks is both a conceptual reference and a practical how-to book that bridges the gap between existing telephony networks and the new world of packetized voice over data networks. Technologies are explained in a context that gives the reader a holistic understanding of voice/data integration. Reader can then follow a complete process to design and implement a variety of network scenarios, leveraging the author's experience with real voice/data networks. The audio accompaniment on CD-ROM will be an excellent companion to demonstrate the expected voice quality using different voice/data networking scenarios. This will allow professionals in the field to demonstrate different sound quality levels to customers.










Integrated DoD Voice and Data Networks and Ground Packet Radio Technology Volume 3. Topological Gateway Placement Strategies


Book Description

Internetwork communication has become an increasingly active area of research in the last few years. However, up to now, most research efforts have been concentrated on the protocol and gateway design issues. The purpose of this study is to investigate the topological design related issues.




Integrated DoD Voice and Data Networks and Ground Packet Radio Technology


Book Description

New research results on the following major questions are reported: Methodology and algorithms for mixed terrestrial-satellite network design are developed. Simple cost functions for mixed network design are proposed and demonstrated to be good estimates. The algorithms are applied to AUTODIN 2 data and sensitivity to variations in cost, traffic level, and other design parameters are presented. A procedure for minimum cost design and for analysis of nonhierarchical circuit switched networks is presented. The problem of connectivity in mobile packet radio networks is solved and implications for predictable networks outlined. Approximate analytical models for initialization of packet radio networks are presented, initialization time is estimated, and operating parameters to obtain minimum initialization time are derived.
