Virtual optical network embedding with sdn architecture based on memetic algorithm

Taking constraints of optical network into account, this paper studies the survivability of virtual optical network embedding in different domain based on Software Defined Network. Optical network virtualization in different areas can promote the efficiency of physical infrastructure among different users and applications. An integrated control model is established in this paper based on the Network Operating System architecture, which separates the route analysis and data transmission. This paper also proposes a failure probability Memetic algorithm to handle the network embedding problem by comparing with the existing baseline algorithm. Simulation results show that the optimized model has a flexible control in multi-domain and significantly improves the failure probability of virtual optical network.
