This report summarizes progress on Washington University's Terabit Burst Switching Project, supported by DARPA and Rome Air Force Laboratory. This project seeks to demonstrate the feasibility of Burst Switching, a new data communication service which can more effectively exploit the large bandwidths becoming available in WDM transmission systems, than conventional communication technologies lik...

Technological innovation in the telecommunications sector is a key contributor to the rapid diffusion of e-business. The steady drive towards semiconductor miniaturisation leads to a continuous decline in the price of telecommunications equipment and increase in performance. Technological change therefore continues to transform the way telecommunications services are provided and used. Telecomm...

In this paper, we consider an optimal (i.e., minimum scheduling length) time slot assignment (for short, TSA) problem in variable bandwidth switching systems. In previous studies, the interdependencies between two consecutive switching con"gurations were neglected. However, it is highly probable that the amount of change between the switching con"gurations will be small. Therefore, it is unnece...

This paper presents an analysis of a cyclic-service tandem queue (M/C/l type queue) with exhaustive services and multiple server vacations, in which a single server takes repeated vacations until it finds at least one message in the first queue after emptying the queueing system. It is assumed that the vacation time is generally distributed, and switch-over times are zero. This paper analyzes q...

In current switching systems, all packets are divided into equal-sized cells before being scheduled. This is because of the fact that cell-based scheduling is easier to be implemented in hardware. In this paper, we consider the case in which the switch does not split packets and the scheduling is done over the whole packets. In this paper, we classify packet-based scheduling algorithms into wai...

The paper deals with the stability properties of linear discrete-time switched systems with polytopic sets of modes. The most classical way of studying the uniform asymptotic stability of such a system is to check for the existence of a quadratic Lyapunov function. It is known from the literature that letting the Lyapunov function depend on the time-varying switching parameter improves the chan...

This paper analyzes two popular heuristics for ensur ing packet integrity in ATM switching systems In particular we analyze the behavior of packet tail dis carding in order to understand how the packet level link e ciency is dependent on the rates of individual virtual circuits and the degree of the imposed over load In addition we study early packet discard and show that the queue capacity nee...

With wide spread use of sensitive nonlinear electronic devices the switching transients are capable of degrading the quality of power. Utilities often switch the shunt capacitor banks to cope up with sagging voltage levels, thereby generating transients, which travel into the network of end users. Capacitor switching can cause over voltage, resonance and in advert tripping of Adjustable Speed D...
