TLDR
The fundamentals of OCSPNs are reviewed and a set of efficient RWA algorithms based on ant colony optimization and genetic algorithms are presented, which improve the performance of this network.Abstract:
Polymorphic optical networks simultaneously support several optical switching paradigms over a single physical network. In this way, they provide service differentiation at the optical layer by employing the most appropriate paradigm for each service. One type of such architecture is the optical circuit-switched polymorphic network (OCSPN), which combines optical circuit switching paradigms with different grades of dynamism. The performance of this network relies on the utilization of efficient routing and wavelength assignment (RWA) algorithms. In this article, we review the fundamentals of OCSPNs and present a set of efficient RWA algorithms based on ant colony optimization and genetic algorithms.read more

Blocking probability evaluation of end-to-end dynamic WDM networks
Nicolas Jara,Alejandra Beghelli +1 more
TL;DR: Two mathematical methods for blocking probability evaluation of end-to-end dynamic WDM networks are proposed and the match between simulation and the proposed methods is excellent, and better than assuming link blocking independence, in all the topologies studied.

Adaptive wavelength routing in all-optical networks
Ahmed Mokhtar,Murat Azizoglu +1 more
TL;DR: This work adopts a more general approach in which all paths between a source-destination pair are considered and incorporate network state information into the routing decision, and performs routing and wavelength assignment jointly and adaptively, and outperforms fixed routing techniques.
