Is Light-Trail Worse Than Light- Tree for Multicast Provisioning in Elastic Optical Networks?
2022 20th International Conference on Optical Communications and Networks (ICOCN)(2022)
摘要
The problem of multicast provisioning in EONs considering splitting loss is formulated by integer linear programming for both light-trail and light-tree. Results show that the light-trail with negligible tapping-power loss can outperform the light-tree. © 2022 The Author(s)
