Single-link failure detection in all-optical networks using monitoring cycles and paths

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(s). For ....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 pa ....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.

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

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—Radio Frequency Identification (RFID) has been developed as an important technique for many high security and high integrity settings. In this paper, we study survivability issues for RFID. We first present an RFID survivability experiment to define a foundation to measure the degree of survivability of an RFID system under varying attacks. Then we model a series of malicious scenarios using stochastic process algebras and study the different effects of those attacks on the ability of the RFID system to provide critical services even ....etc
