US Navy training commands use a local area and a wide area network known as the Versatile Training System II (VTS). VTS furnishes word processing, electronic mail, and data base functions, all of which can be transferred throughout the network. Enabling this rather old system is a mainframe at each training site with user terminals dispersed throughout the command. The system was installed and is maintained by civilian contractors. VTS does not have the capabilities to develop and maintain curriculum, because advanced word processing and graphics are required. This results in the Navy's training commands having redundant computer systems. Due to the shortcomings of VTS, a need exists to establish local area networks at training commands. Additionally, a wide area network is required that would give a standard package of electronic mail and file transfer capabilities. All of this must be accomplished using existing command computer resources and at a more economical price than the remaining life cycle cost of VTS. To facilitate the design, the systems engineering concept is utilized. A specific design is developed to fill the identified deficiency. Existing resources and "off the shelf" material are to be used exclusively. / Master of Science

To achieve information superiority in a coalition environment the U. S. has to seamlessly integrate coalition members, both NATO and Non-NATO, into its command and control processes along all echelons of military operations. In a coalition environment, it is extremely challenging to fuse multinational information systems to achieve seamless integration. This thesis focuses on the security issues that are involved in establishing coalition network interoperability. The coalition environment is defined in terms of purpose, command structure, mission area, and control functions. Network and information protection are discussed in terms of minimizing the threats to information systems security. Coalition information system user requirements are defined and some of the security mechanisms required to meet those requirements are discussed. Current solutions to secure coalition network interoperability are surveyed, followed by conclusions, recommendations and areas for further study. / US Navy (USN) author

A thesis submitted to the Faculty of Engineering, University of the '\Vitwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy / THIS STUDY identifies and evaluates factors that affect call connections in the South African public data networks, modelling these factors to aid data network planning. The research shows the relationship between the economic rank of each region served and the data communication resources required for that region. Moreover, it shows the resources required between regions. THE THRUST of this thesis is that the volume of cans from a region can be estimated from its economic ...k and more than 75% olthe variation in the volume of calls between regions can be explained using the ranks of the originating and terminating regions. To prove this, records of more than four million calls are accumulated for all regions of the South African packet switched data network. An appropriate filtering and aggregation method is developed. EXISTING growth models including the gravity model are separately examined. Based on probability and dimensional arguments, the Bell System growth model is selected. It is revealed that the success of this model depends on one premise being satisfied: this model tacitly anti implicitly assumes that the originating and terminating calls are statistically independent. RETURNING to the data network, it is found that the call connections (after filtering and aggregation) display dependence of destination on origin. Reasons for the dependence are discovered. Multiple linear regression reveals the nature of this dependence. Surprisingly, distance is not a factor. The importance of regional ranks and an inter-regional indicator variable are also discovered. FINALL Y, call volume from a node is shown to be directly linked with the weighted Gross Regional and Industrial Product of the region. This quantity, in tum, is inversely related to the rank of the region. Call connections are then modelled to be equal to the call connections within the first tanked region divided by the product of the originating region's rank and the terminating region's rank. This simple and economical model explains 76% of the variations that occur in call connections. It has proved its use by being included in the data transfer services product-line report. / Andrew Chakane 2018
