<p><a href="http://www.osa-jon.org/virtual_issue.cfm?vid=22">Feature Issue on Waveband Switching, Routing, and Grooming</a></p>We deal with the optimal design of a survivable optical mesh network supporting end-to-end and subpath waveband switching (WBS) in order to compare various WBS schemes according to a given cost function. An integer linear programming formulation is proposed to minimize the global network cost, which is expressed in terms of port cost, fiber cost, and propagation delay cost. We assume a single-layer multigranularity optical cross-connect (MG-OXC) node with a variable number of incoming fibers and a fixed number of wavelengths per waveband. The results show that on our case-study networks WBS with joint end-to-end and subpath wavebanding guarantees a gain of up to 22% and 85% in port number and global network costs, respectively.
