Abstract

With the demand for multimedia and computational science applications, guaranteed performance communication services have become a necessary feature of future high-speed networks. These communications services should possess a high level of sophistication so that they can easily adapt the network to the wide variety of applications soon to be seen, thereby allowing the network to increase its availability and flexibility. Availability is the ability of the network to accommodate as many real-time clients as possible without violating any client's performance guarantees, while flexibility is the ability to adapt to changing network state and client demands in order to maintain the performance guarantees and quality of service promised to the client. Flexibility also refers to the ability of the network to easily increase the variety of real-time services that it offers. It is our contention that availability and flexibility can be enhanced in a network by providing the network with the ability to modify the performance parameters and/or the route of any guaranteed performance connection in the network without violating the previously made performance contracts.In this paper, we present a scheme for dynamically managing guaranteed performance service connections and experimental results to verify the correctness and usefulness of the scheme. The motivation for this scheme, Dynamic Connection Management (DCM), is discussed, and detailed descriptions of the DCM modification contracts and algorithms are provided. A survey of guaranteed performance services protocols, architectures, and routing algorithms are presented together with their relevance to this work. A simulator has been built, and preliminary experiments and analyses were done on the scheme. The paper concludes with a summary and some topics for future work.
