Title
Multicast Routing And Wavelength Assignment With Shared Protection In Multi-Fiber Wdm Mesh Networks: Optimal And Heuristic Solutions
Abstract
While the problem of multicast routing and wavelength assignment (MC-RWA) in optical wavelength division multiplexing (WDM) networks has been investigated, relatively few researchers have considered network survivability for multicasting. This paper provides all optimization framework to solve the MC-RWA problem in a multi-fiber WDM network that call recover from a single-link failure with shared protection. Using the light-tree (LT) concept to support multicast sessions, we consider two protection strategies that try to reduce service disruptions after a link failure. The first strategy, called light-tree reconfiguration (LTR) protection, computes a new multicast LT for each session affected by the failure. The second strategy, called optical branch reconfiguration (OBR) protection, tries to restore a logical connection between two adjacent multicast members disconnected by the failure. To solve the MC-RWA problem optimally, we propose an integer linear programming (ILP) formulation that minimizes the total number of fibers required for both working and backup traffic. The ILP formulation takes into account joint routing of working and backup traffic, the wavelength continuity constraint, and the limited splitting degree of multicast-capable optical cross-connects (MC-OXCs). After showing some numerical results for Optimal Solutions, We propose heuristic algorithms that reduce the computational complexity and make the problem solvable for large networks. Numerical results Suggest that the proposed heuristic yields efficient solutions compared to optimal solutions obtained from exact optimization.
