Restorable routing algorithm in optical networks by reducing blocking probability

Restorability of a network refers to a capability of a network to provide continuous service in the presence of failures and it also defines how a network restores to the actual position after overcoming a failure. In a WDM network, a single channel may be carrying no of gigabits of data per second. A single failure may cause a disturbance in a large amount of services. A network that is built on fiber-optics technology sends data digitally in the form of light through connected fiber. Optical networks increase the Transmission capacity and speed of the network. This paper presents a restorable routing algorithm that reduces blocking probability and compares the proposed work with the conventional algorithms. In this work, we have presented a quick and efficient heuristic for restorable routing.
