Anew class of switching architectures for broadband packet networks, called Shumeout, is introduced in this paper. Its interconnection network is a multistage structure built out of unbuffered 2x4 switching elements. Shuffleout is basically an output-queued architecture in which the number of cells that can be concurrently switched from the inlets to each(More)
In this paper, we study the problems of resource allocation and admission control of traffic flows with guaranteed Quality of Service. Specifically, we deal with traffic flows regulated by Dual-Leaky Buckets and we establish the analytical expressions for (a) the minimum capacity to be allocated in order to guarantee the required delay performance and for(More)
The Internet is currently facing a twofold challenge: to increase network capacity in order to accommodate a steadily increasing number of users, and to guarantee the Quality of Service for existing applications as well as for new multimedia applications requiring real-time network response. In order to meet these requirements, the Internet Engineering Task(More)
The early identification of applications through the observation and fast analysis of the associated packet flows is a critical building block of intrusion detection and policy enforcement systems. The simple techniques currently used in practice, such as looking at the transport port numbers or at the application payload, are increasingly less effective(More)
This paper proposes a routing algorithm for the interconnection of multiple processors based on the shortest-path and deflection-routing principles. The routing algorithm, named SPDRA (Shortest Path and Deflection Routing Algorithm), is applied to multiprocessor systems with a single-stage shuffle physical topology. SPDRA is general-purpose, as opposed to(More)
