D6.7_PASSION_WDM_planner

The tool has been programmed in open-source R, making use of the igraph library for graph analysis. The tool is fed with the optical characterization of PASSION hardware (for OSNR calculations), hierarchical network topology and traffic matrix, and delivers as outputs, both primary and backup lightpaths, wavelength assignment per fiber link, and techno-economic metrics of the solution, including per-node design and inventory cost.

The objective of the tool is exploiting the specific capability of PASSION to perform IP-offloading at intermediate hierarchical levels, as explained in section 2, by automatically computing paths to interconnect all optically all edge nodes (starting at hierarchical level 4) to the closest core nodes via disjoint primary and secondary paths. The computed deployment cost assumes a pay-as-you-grow business model where the operator is charged only for the licensed active VCSELs it is using.
