Storage Area Networks (SANs) have become an essential part of today’s enterprise computing. The paper reports the design of SANs based on metro Wavelength Division Multiplexing (WDM) networks technologies. It reviews related SAN technologies. It also presents analysis and simulation results of a proposed architecture. Throughput, delay and packet dropping probability results are presented under...

An H.263-based video transceiver is contrived, which maintains a near-constant bitrate and due to the proposed packetisation and packet dropping regime it provides near-unimpaired video quality for frame error rates upto 5%. The target frame error rate is maintained by invoking a novel power-control technique.

New generations wireless cellular networks, including 3G and 4G technologies, are envisaged to support more mobile users and a variety of wireless multimedia services. With an increasing demand for wireless multimedia services, effective Radio Resource Management (RRM) is needed to improve system performance by maximizing the overall system capacity and maintaining the Quality of Service (QoS) ...

In this paper we consider the problem of joint optimal power and admission control for a single user queue. The user may be in a finite set of channel fading states, each of which corresponds to a certain power-rate function. The user may choose a particular transmission power level and incur a cost that increases with the power. Packets arrive at the queue as a Poisson process with a constant ...

Buffer sizing in Internet routers is a fundamental problem that has major consequences in the design, implementation, and economy of the routers, as well as on the performance observed by the end users. Recently, there have been some seemingly contradictory results on buffer sizing. On the one hand, Appenzeller et al. show that as a direct consequence of desynchronization of flows in the core o...
