Space switch fabric architecture is shown in figure. The switch consists of N incoming and N out going fiber links, with n wavelengths running on each fiber link. The switch is slotted, and the length of the slot is such that an optical packet can be transmitted and propagated from an input port to an out put optical buffer.

The switch fabric consists of three parts; optical packet encoder, space switch, and optical packet buffer. The optical packet buffer works as follows. For each incoming fiber link, three is an optical demu ....etc

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc

ABSTRACT
The current fast growing internet traffic is demanding more and more network capacity everyday. As telecommunication and computer communications continue to converge, data traffic is gradually exceeding telephony traffic. This means that many of the existing connection-oriented or circuit-switched networks will need to be upgraded to support packet-switched data traffic. The concept of wavelength division multiplexing has provided us an opportunity to multiply network capacity. Current pho ....etc

Abstract
Dense Wavelength-division multiplexing (DWDM) technology offers tremendous transmission capacity
in optical fiber communications. However, switching and routing capacity lags behind the transmission
capacity, since most of today’s packet switches and routers are implemented using slower
electronic components. Optical packet switches are one of the potential candidates to improve switching
capacity to be comparable with optical transmission capacity. In this paper, we present an optically
transparent ATM (OPATM) switch t ....etc

1. INTRODUCTION

The growth -of existing and new services will create a large increase of traffic flow in telecommunication network in the coming years .The demand for bandwidth in a communication network increase continuously .The world wide web alone Ëœfor example require a yearly 8 fold increase in bandwidth per user . All optical networks may be the only solution to cope with such increasing bandwidth .In these network transmitter signals remain in optical format on the way from source to destination

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc
