Network design for multi-layered photonic IP networks considering IP traffic growth

摘要

In order to transport ever-increasing IP traffic effectively, Photonic IP networks that employ wavelength routing and layer 3 cut-through are very important. This paper proposes a network design algorithm that minimizes the network cost considering IP traffic growth for multi-layered photonic IP networks that consist of electrical LSPs (Label Switched Paths) and optical LSPs. We evaluate the network cost obtained from the developed network design algorithm that considers IP traffic growth and compare it with the static zero-based algorithm. The static zero-based algorithm does not consider the progressive IP traffic growth. The comparisons show that our proposed algorithm is very effective; the cost increase from the cost obtained with zero-based algorithm was marginal.
