A novel technique to protect multicast communication over WDM mesh networks

Protecting communication from network failure is a major concern in current days. Here we have proposed an efficient algorithm which provides full protection over single link failure in a WDM optical fiber network with limited wavelength channels and reduces blocking probability by reducing backup wavelength channel requirement, thus it maximizes throughput. In this paper at first we have formulated the multicast protection problem and then proposed our algorithm which reduces the wavelength channel requirement by scatter minimization technique. Finally, we have shown the efficiency of the proposed technique through simulation over physical optical fiber mesh network model.
