Abstract

We propose a novel optical multicast tree design algorithm for hierarchical optical path networks that exploit waveband routing. To efficiently groom wavelength multicast trees into waveband trees, we define a generalized inclusive relation between node groups that identifies neighboring destination groups. The algorithm then establishes a minimum weight waveband tree that contains the wavelength multicast trees that include the neighboring destinations. Numerical experiments confirm that the proposed waveband multicast can significantly reduce the number of optical switch ports.
