Elastic Multi-Layer Resilient IP-over-Flexgrid Networking: Detailed Cost Analysis with Bandwidth-Variable Transponders

Abstract
We introduce a mixed-integer optimization model for two-layer IP-over-Flexgrid networks, and present a cost study performed using the CPLEX package for the introduced model. The study concerns a generic German network with 12 nodes and 20 links in the optical layer, and a set of six IP traffic matrices with increasing demand volumes. The optimization assumes a hot-standby mechanism in the optical layer to make the network resilient to cable cuts. The dominant cost drivers are bandwidth-variable transponders. The numerical results reveal that due to the huge spectral capacity of a single fiber, the spectrum allocation problem simplifies significantly in practice. However, the routing problem minimizing the total cost of employed... (More)

The numerical results reveal that due to the huge spectral capacity of a single fiber, the spectrum allocation problem simplifies significantly in practice.
