The technological evolution of telecommunication networks in recent years has shown that the availability of transmission bandwidth has been growing at a faster pace than the STNitChing bandwidth inside network nodes [4]. This means that in the near future electronic switching will become the perfonnance bottleneck of high-capacity networks. The cost of a Switching device (be it an IP router, a...

A discrete-time communication framework is studied under an approximate socalled "stop protocol" related to the lost-calls-held protocol. An explicit insensitive product form expression as recently obtained under a less realistic recirculated protocol is shown to remain valid. This extension seems of both practical and theoretical interest. Applications include: • Circuit switching structures •...

Circuit-switched Banyan interconnection networks can be built from simple switching elements that do not have logical processing or buffering capabilities. This paper describes a distributed technique for dynamic control of such a network, so that circuits can be established in response to the changing needs of a parallel application. Control information is interleaved with data, thus avoiding ...

The goal of this paper is to address why MPLS (Multiprotocol Label Switching) is necessary, limitations of ATM, how MPLS performs fast routing, the architecture of MPLS, the protocols used in MPLS, how MPLS will support multiple Quality of Services, the applications of MPLS.

This paper reports on an optical packet switching network demonstrator, constructed under the EPSRC-funded WASPNET project. Header deletion and insertion, routing, switching and contention resolution were demonstrated, facilitating optical packet transmission over 14 nodes. 2001 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (060.4250) Networks

The paper presents a new type of parallel router architecture based on a combinatorial arrangement of routing processing elements. The suggested approach reveals some properties of combinatorial designs, useful for economical implementation of parallel routing. In particular, such an architecture has explicit advantages for packet switching and multicast routing implementation. Key-Words: packe...

This paper addresses the design of an application-specific processor with emphasis on packet processing applications. In this domain, demands for increasing the performance and the ongoing development of network protocols both call for flexible and performance-optimized engines. We present a flexible engine that is optimized for packet switching operations. The architecture and instruction set ...

| Developments in telecommunications technology have outpaced progress in teletraac methods and practices. As a result, the planning and dimensioning of even the latest information-age services is, by default, commonly done on the basis of classical teletraac methods developed for circuit switched voice networks. In this paper, we will discuss recent traac measurement studies which have demonst...
