Abstract
ABSTRACT This project aims to design a DWDM optical network for PALTEL Company. The design includes performing link budget taking into account the fiber span and the losses that may on the network. Moreover, studying and analyzing the services that must be carried on the network to determine the required number of lambdas needed for the transmission in addition to provide the right paths for routing the services between the nodes in the network, providing protection for the design to ensure that the network is fault- tolerant and impervious to outages. This is done by assigning secondary paths that work as backup in the case of link failure. In this project we have also implemented a desktop application based on Java Language for the purpose of monitoring and managing the DWDM network. It includes set of modules, the first module works on finding the best available route between two nodes when a new lambda needs to be defined on the network. The second module is used in the case of link failure or fiber cut, it retrieves all the customers available on the affected link , estimates their carried traffic and finds a new temporary route to carry the traffic. The rerouting is done for the highest priority customers only. The third module keeps tracking for the utilization of the traffic on the international links , and gives an indication when the capacity exceeds the limit on a certain link .
