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

In optical WDM networks, since each lightpath can carry a huge mount of traffic, failures may seriously damage the end-user applications.As a result, fault-tolerance is an important issue in these networks. The primary path is the light path which carries traffic during normal operation. in case of a failure, the traffic is rerouted on a backup path. a reliable and fault-tolerant routing algorithm is discussed in this paper for establishing primary and backup path. load balancing is used to establish the primary path. In this method, the pag ....etc

CWDM
ABSTRACT
Sending and receiving of messages from one place U) another has always been a matter of great importance. So we should select the proper ! communication systems. Today optical fiber communication is widely used because of its advantages.
An important issue in the field of communication is the effective utilization of the capacity of a communication channel. Inorderto increase the capacity we use multiplexing techniques. WDM is a technique where modulated light from several sources of distinct wavelengths a ....etc

WDM Concept and Components


Why WDM?

Capacity upgrade of existing fiber networks (without adding fibers)

Transparency: Each optical channel can carry any transmission format (different asynchronous bit rates, analog or digital)

Scalability Buy and install equipment for additional demand as needed

Wavelength routing and switching: Wavelength is used as another dimension to time and space

WDM, CWDM and DWDM

WDM technology uses multiple wavelengths to transmit info ....etc

Switching and Traffic Grooming in WDM Networks at java

Abstract: We consider the role of switching in minimizing the number of electronic ports (e.g., SONET ADMs) in an optical network that carries sub-wavelength traffic. Providing nodes with the ability to switch traffic between wavelengths, such as through the use of SONET cross-connects, can reduce the required number of electronic ports. We show that only small switches distributed among the nodes in the ring are needed for significant reductions in the number of ports. We charac ....etc
