Traffic Grooming in PCE-based Architecture Combined with RWA Utilizing Dynamic Fiber State Information

Abstract

Wavelength routing in the backbone of pure optical networks is the future. Wavelength division multiplexing and generalized multi-protocol label switching are the control plane technologies imbibed in futuristic pure optical networks. To improve the overall connection blocking probability of pure optical networks, efficient information scheduling algorithm is required to be imbibed with the in-use dynamic routing and wavelength assignment techniques. The traffic scheduling algorithm which has been introduced in this research work decreases the blocking probability of the connections in pure optical networks by assigning weights to every connection request according to certain connection parameters. The above results in noticeable improvements in the resource utilization of pure optical networks and can be practically implemented in present day and future pure optical telecommunication networks. © 2016 IETE.
