A Simulation Study of IPv6 to ATM Flow-Mapping Techniques

This paper presents a simulation study into the problem of conveying Internet protocol (IP) packets over an asynchronous transfer mode (ATM) network in cases where quality of service (QoS) is an important consideration. The main focus of the work is on mapping IP packet flows onto ATM cell streams, particularly for the purpose of maintaining the QoS requirements of continuous media (audio and video) traffic. Simulation models of two different flow-mapping scenarios are described, and results of an evaluation of the flow-mapping process are presented. These results are also used to validate an analytical solution to the problem, which has been developed in a separate but related piece of work.

A control framework to develop smart grid communications: possible pointers from multiservice network research

This paper addresses the challenge of developing an architecture for the smart grid with the particular focus to support smart grid communication. It considers the smart grid system in general to identify the relationship between the power distribution and communication networks, and then focuses mainly on smart grid communication requirements. It observes the similarity between the quality of service (QoS) requirements for smart grid communications and those identified in multiservice networking. It reviews the principles of open communication and introduces architectures for open communication that have been enhanced to meet the requirements of multiservice. It discusses previous research into multiservice with a review into recent work focused on meeting the multiservice requirements of smart grid communications. Based on these, the paper presents key specific pointers toward defining a contextual control framework for the data transport system of the smart grid.

An Architectural Approach for Integrating Performance Evaluation into the Systems Design Process

This paper presents work aimed at integrating performance evaluation into the systems design process. It considers the problem of providing a performance evaluation service to system designers that will allow practitioners from different application areas to specify the system in a level of abstraction that is readily understandable in their own particular application area, and then to use this specification to automatically generate a solution for the performance evaluation of that system. It presents the proposal for an open-systems-like architectural approach to the problem of providing these services and outlines the research issues that need to be addressed in the development of this architecture

A simulation study of IPv6 to ATM flow mapping techniques

This paper presents a simulation study into the problem of conveying IP packets over an ATM network in cases where quality of service (QoS) is an important consideration. The main focus of the work is on mapping IP packet flows onto ATM cell streams, in particular for the purpose of maintaining the QoS requirements of continuous media (audio and video) traffic. Simulation models of two different flow-mapping scenarios are described, and results of an evaluation of the flow mapping process are presented. These results are also used to validate analytical solutions to the problem, which have been developed in separate work.
