    Abstract :

    Survivability of a network refers to a network's capability to provide continuous service in the presence of failures. In a WDM network, as a single channel may be carrying tens of gigabits of data per second, a single failure would cause a huge amount of service disruption to a large number of users. Design of survivable optical networks has therefore attracted the attention of the research community. This paper deals development of an efficient technique for designing survivable routing schemes for optical networks and comparison of the proposed work with the conventional algorithms.In this thesis,we have presented a quick and efficient heuristic for survivable routing. In current WDM networks, it is possible to support hundred sof WDM channels on a single fiber.Therefore,the cost of the transmitters and the receivers and hence the number of light paths is becoming the main factor in determining the cost of a WDM network. We have tried to keep the number of light paths required to implement a topology as low as possible. The results shown in thesis prove that the blocking probability of the proposed algorithm increased with the increase in the offered load per unit link. We have also compared the two conventional algorithm first fit routing algorithm and best-fit routing algorithm. The comparison clears proposed algorithm is effective routing algorithm and it can be used for the networks with larger load.
