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

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

4 THERMODYNAMIC CYCLES



Abstract

Energy sources such as coal, natural gas, or petroleum cannot be used directly to
perform a work. These sources are burned to generate heat which is then converted to
mechanical or electrical energy. These processes are governed by thermodynamic
cycles and the efficiency of the overall process depends mainly on the choice or
efficiency of the cycle. A number of thermodynamic cycles using various working
fluids have been suggested. The description and analysis of these c ....etc

Design of p-Cycles for full node protection in WDM Mesh Networks


INTRODUCTION

WDM techniques enable a single fiber to carry multiple
non-overlapping channels, and a single channel can operate
at the speed of up to 100 Gbps. WDM networks carry huge
amounts of traffic. As optical WDM networks are occasionally
prone to a single failure of network infrastructure (e.g., a fiber
cut or a node failure), survivability is an essential requirement
in the design of WDM networks.

Single-Link Failure Detection in All-Optical Networks Using Monitoring Cycles and Paths

Abstract:

In this paper, we consider the problem of fault localization in all-optical networks. We introduce the concept of monitoring cycles (MCs) and monitoring paths (MPs) for unique identification of single-link failures. MCs and MPs are required to pass through one or more monitoring locations. They are constructed such that any single-link failure results in the failure of a unique combination of MCs and MPs that pass through the monitoring location( ....etc

Theoretical Analysis

The accurate analysis of the various processes taking place in an internal combustion engine is a very complex problem. If these processes were to be analyzed experimentally, the analysis would be very realistic no doubt. It would also be quite accurate if the tests are carried out correctly and systematically, but it would be time consuming. If a detailed analysis has to be carried out involving changes in operating parameters, the cost of such an analysis ....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
