Modeling and performance analysis of ATM LANs

Asynchronous Transfer Mode (ATM} is a method of data transmission using small fixed-length cells. This thesis presents a model of an ATM LAN which provides a realistic representation of data transmission over the system by explicitly modeling both the ATM network and the applications running over that network. Coloured timed Petri nets are used to create a compact model that is capable of representing a variety of different protocols at a high level of detail. The model is designed to allow easy reconfiguration or addition of detail at different levels of the system. Simulation is used to evaluate the performance of the model, and results are compared to actual data gathered from the Memorial University campus network

Paying for high speed networking services

The idea of a free network is a myth of the past. Networking costs are expected to remain a burden to future IT budgets, no doubt raising questions regarding the payment of such services. Users do not normally pay to use local area networks, as companies tend to own their LANs. However, when wide area or international networks are considered, the situation is different. It is argued that in these cases the invoicing and payment system should be integral to the network's communication protocol. This implies changes to the networking protocol (to handle invoicing) as well as a new look at customary ideas of representing currency (to handle payment). In this dissertation, an invoicing and payment scheme that uses electronic cash and is implemented as part of the basic ATM protocols is discussed. The main advantages of this scheme can be summarized as a low administrative overhead and user privacy.Computer ScienceM. Sc. (Computer Science

Satellite Networks: Architectures, Applications, and Technologies

Since global satellite networks are moving to the forefront in enhancing the national and global information infrastructures due to communication satellites' unique networking characteristics, a workshop was organized to assess the progress made to date and chart the future. This workshop provided the forum to assess the current state-of-the-art, identify key issues, and highlight the emerging trends in the next-generation architectures, data protocol development, communication interoperability, and applications. Presentations on overview, state-of-the-art in research, development, deployment and applications and future trends on satellite networks are assembled
