Unified and Automated Fault Management Platform for Optical Networks

Abstract : A united and automated fault management platform for heterogeneous optical networks is quite important for telecom operators to monitor and respond to various levels of network events. In this demo, we are demonstrating the details of the design, implementation and evaluation of the proposed Optical router platform while targeting to manage the underlying optical network of a telecom operator in real time. The proposed system consists of three major building blocks i) a data collection layer that is integrated with the telecom operator infrastructure, (ii) data association and analysis layer that is used to measure the severity levels based on pre-de?ned alarm severity levels and constraints, and (iii) user interface layer that is on top of management and infrastructure layer which is used to demonstrate the faulty optical lines and is also integrated with fault management systems. Through the dashboard interface of the proposed Optical router platform, telecommunication operator’s network optimization experts can easily detect the problems related to either or DWDM link and can take appropriate actions.
 Location information is of paramount importance for wireless sensor networks (WSN). The accuracy of the collected data can significantly be affected by an imprecise positioning of the event of interest. Despite the importance of location information, real system implementations that do not use specialized hardware for localization purposes have not been successful. In this paper, we propose a location estimation scheme that uses a probabilistic approach for estimating the location of a node in a sensor network. Our localization scheme makes use of additional knowledge of topology deployment. We assume a sensor network is deployed in a controlled manner, where the goal of the deployment is to form a grid topology.
 The server is expensive to purchase A specialist network operating system is needed
 In this paper, we attempt to answer these and other related questions by following a careful analytical approach. Specifically, we first show that when the number of cheating destination client system is greater than or equal to a given threshold, there do not exist any two-dimensional distance-based localization algorithms that can guarantee a bounded link error in router. Furthermore, when the server transfers files, we configure the router and enable it to send to destination client. that can always guarantee a efficient data transfer from source to destination via router control if any error occurs in link while transfer it automatically reconfigure the router . Finally, we achieve efficient data transfer.
 All files are stored in a central location Network peripherals are controlled centrally.
