For several years, more and more people are joining the Internet and various kind of packets (so called transaction-, block-, and stream-types) have been transmitted in the same network, so that poor network conditions cause loss of the stream-type data packets, such as voices, which request smaller transmission delay time than others. We consider a switching node (router) in a network as an N-...

Abstract: The dead-time effect, as an intrinsic problem of the converters based on the half-bridge unit, leads to distortions in the converter output. Although several dead-time effect compensation or elimination methods have been proposed, they cannot fully remove the dead-time effect of blanking delay error, because the output current polarity is difficult detect accurately. This paper utiliz...

The optical switching time of twisted-nematic liquid-crystal cells using the liquid crystals, 5CB (C(5)H(11)-Ph-Ph-CN), 5OCB(C(5)H(11)-O-Ph-Ph-CN) and PCH5 (C(5)H(11)-Cy-Ph-CN) have been characterized as a function of temperature, bias voltage and switching voltage, V. The transition time from 90% to 10% transmission scales as V(-1.9) and is limited to 30 to 50 ns by the liquid-crystal breakdow...

First, we will discuss the limitations and difficulties of MPλS, and we will address that the photonic packet switching will be an ultimate solution to solve the problems of MPλS. Next, we will focus on the OC-based photonic packet switching. The advantages of OC-based photonic packet switching include ultrafast photonic label processing capability, optical buffering using WDM fiber delay lines...

Data traversing packet networks experience varying delays, resulting in inter-arrival jitter. This can result in degraded performance in real-time multimedia communications applications if the jitter delays are large or unaccounted for in the receiver application. This paper examines modeling and simulation of network jitter delay for real-time multimedia communications applications. We examine...

The provision of real time services through a Packet Switched Network, requires the adoption of end-toend synchronization methods. Several of these methods, are compared and a specific hardware solution is discussed. Results obtained through a specially designed Simulation Programme are included, for several network time delay jitter distributions and synchronization methods. These results are ...

Delay jitter control for real-time communication in a packet switching network.

In this work, it has been demonstrated through experiments that Long Range Dependence (LRD) in internet traffic is indeed affecting the queueing performance. Queueing performance is being degraded as the self-similarity of the packet arrival process increases. Here, the link buffer capacity and queueing delay exhibits super-linear relationship. This in turn has led to the proposal of resource p...

Optical burst switching networks have received a lot of attention in the research community in the recent years. The JET protocol, first proposed by Qiao and Yoo in 1997 in [YQ97a, YJQ97], is used for resource allocation in these networks. Up to the present, the JET protocol has been studied in networks that use wavelength conversion [YQ97b, GDSB01a]. In this paper the JET protocol is discussed...
