atm switching systems are required to maintain ordering for cells within a given virtual circuit This is most commonly achieved using a switching system in which cells in a given virtual circuit are routed along a common path through the switch ing system This solution has the drawback that it can lead to signi cant virtual circuit blocking unless the switching network is engineered with a larg...

Recent research has shown that traffic in Ethernet and other networks tends to exhibit properties of self-similarity such as long-range dependence and a high degree of correlation between arrivals. This paper investigates the impact of the switching network on the self-similar properties of the traffic. This simulation study reveals that switching networks tend to reduce the self-similarity of ...

Multi-Channel/Port communication structures are often found in multiaccess networks and switching systems, where data packets from input channels/ports are directed to their destinations of output channels/ports, following certain traffic assignment rules. In this paper, we propose a simple algorithm, the K-HOL algorithm, to expedite the processing of multi-channel/port traffic assignment. Recu...

We study discrete time linear constrained switching systems with additive disturbances, in which the switching may be on the system matrices, the disturbance sets, the state constraint sets or a combination of the above. In our general setting, a switching sequence is admissible if it is accepted by an automaton. For this family of systems, stability does not necessarily imply the existence of ...

The resonant power conversion having many advantages over conventionally adopted pulse width modulation that includes a high efficiency, low electromagnetic interference, small volume, low switching losses, and light weight of components due to a high switching frequency, and low reverse recovery losses in diodes owing to a low di/dt at switching instant. This paper presents the doubly loaded r...

SONET technology has made high-speed self-healing ring (SHR) architectures practical and economical for use in intra-LATA telecommunication networks. This paper reviews a class of SONET SHR architectures and their control schemes. The SHR architectures can be divided into two basic classes: bi-directional SHRs (B-SHRs) and uni-directional SHRs (U-SHRs). Bidirectional SHRs using four fibers and ...

Switching elements are an essential part of many devices widely used in applications. For instance, appropriate switching circuits are used in power electronics to achieve the conversion of electrical energy from one form to another [1]. Also, in many areas of engineering, relay devices are often used to synthesize feedback strategies able to achieve a desired control goal [2]. Other examples c...

The self-consistent decay-of-mixing (SCDM) semiclassical trajectory method for electronically nonadiabatic dynamics is improved by modifying the switching probability that determines the instantaneous electronic state toward which the system decoheres. This method is called coherent switching with decay of mixing (CSDM), and it differs from the previously presented SCDM method in that the elect...

Optical Burst Switching (OBS) is an experimental network technology that enables the construction of very high capacity routers, using optical data paths and electronic control. In this paper, we study two designs for wavelength converting switches that are suitable for use in optical burst switching systems and evaluate their performance. Both designs use tunable lasers to implement wavelength...
