Virtual networks mapped over a physical network can suffer from network disconnection due to disasters. We propose an integer linear programming model to restore physical links with maximizing connectivity of virtual networks.
We analyze the performance features of dynamic flexible grid WDM networks from the mathematical angle. A continuous-time Markov model for links is proposed and matches Monte Carlo simulation results exactly.
This paper analyzes the development tendency of optical networks under multi-service in the future, proposes an original ideology of transport adaptability in reconfigurable all-optical networks, researches on the key techniques of the complex coupling mechanism and dynamic controlling in the process of selecting lightpaths and tuning, such as the architecture of complex adaptability system (CAS)...
