我们提出了一种新的光组播树设计算法的层次光路网络，利用波带路由。为了有效地将波长组播树梳理成波带树，我们定义了节点组之间的广义包容关系，该关系识别相邻的目的地组。然后，该算法建立一个最小的重量波带树，包含波长组播树，包括相邻的目的地。数值实验表明，提出的波带组播可以显着减少光交换端口的数量。
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.
