Abstract :
This work deals with the survivable optical network design problem for static multicast traffic, subject to simple node fails. Given a set of multicast request, it is proposed an algorithm based on Multi-Ojective Ant Colony Optimization which tries to find the best network design, as well as the primary and back-up multicast trees, with protection against node fails. The proposed algorithm simultaneously minimizes the network design cost and the maximum end-to-end optical delay. The experimental results over different instances show the benefits of three protection approaches based on total or partial network reconfiguration.
