Frame level H.264/MPEG encoded VBR video traffic is highly bursty in nature because of inherent coding techniques employed. Multiplexing traffic from many VBR sources results in smoothing of generated traffic from the multiplexer, and improves Statistical Multiplexing Gain (SMG). An efficient multiplexing methodology can greatly enhance resource utilization. Performance of multiplexer can be es...

The control of source-coded traac at a multiplexer has been a topic of extensive research. Traditional approaches typically use feedback information on the buuer level in designing the control policy. While important , buuer levels capture only part of the information about the overall system state. By setting up this problem as a Markov decision process, we show that using information on the s...

We describe a heuristic scheduling approach for optimizing floating-point pipelines subject to input port constraints.The objective of our technique is to maximize functional unit reuse while minimizing the following performancemetrics in the generated circuit: (1) maximum multiplexer fanin, (2) datapath fanout, (3) number of multiplexers, and (4) number of registers. For a set of systems biolo...

The determination of packet loss rates in multiplexers is an important problem that has received much attention in the literature. This paper considers the problem of estimating, via simulation, extremely low packet loss rates in a voice-data multiplexer. The multiplexer gives priority to voice packets, unless the data queue length exceeds a threshold. To eeciently simulate such low loss rates ...

In this paper, the possibility of using a silicon waveguide based microring resonator as a nonlinear all-optical switch is described under low power operation through a two-photon absorption effect. All-optical multiplexer/demultiplexer scheme based on two cascaded microring resonators has been proposed and described. The proposed circuits require smaller number of ring resonators and a single ...

The emergence of space division multiplexing (SDM) for ultrahigh capacity networks has heralded pioneering Petabit-class optical transmission systems. In parallel to novel SDM fibers, a new class of components to enable scalable, low-loss schemes for unlocking fiber capacity is being developed. In this work, an all-fiber mode selective photonic lantern mode multiplexer designed for launching in...

Estimating the cell loss probability in an ATM multi-plexer is a key issue in network management and traac control such as call admission control and bandwidth allocation. In this paper, we derive a new approximation to estimate the total and individual cell loss probabilities in an ATM multiplexer fed by a superposition of heterogeneous on-oo sources with exponentially distributed on and oo pe...

A key problem for modern network designers is to characterize/model the “bursty” traffic arising in broadband networks with a view on predicting and guaranteeing performance. In this paper we attempt to unify several approaches ranging from histogram/interval based methods to “frequency domain” approaches by further investigating the asymptotic behavior of a multiplexer carrying a large number ...

A method to evaluate internal voltages through a builtin test structure is presented. Multiplexers are used to increase accessibility. The test structure does not affect normal operation of the circuit. Individual subcircuits can be tested selectivel,v based on evaiuated internal voltages.

We develop a methodology for characterizing the superposi-tion process of N 2 discrete-time arbitrary on/oo sources. The superposition is a discrete-time semi-Markov process with O(2 2N) states. We use the superposition model to analyze a nite-buuer statistical multiplexer with multiple arbitrary on/oo input sources. We study the eeect of various traac parameters on the queueing performance.
