Experimental Evaluation of Orchestrating Inter-DC Quality-enabled VNFFG Services in Packet/Flexi-Grid Optical Networks

44th European Conference on Optical Communications (ECOC 2018)An implemented Cloud/Network Orchestrator to dynamically serve VNFFGs in remote DCs through a Multi-Layer Network (packet/flexi-grid optical) is evaluated. Two network information and path computation approaches are adopted by the Orchestrator being experimentally benchmarked with a number of performance metrics.This work is partially funded by the Spanish MINECO DESTELLO project (TEC2015-69256-R) and the EU H2020 5G TRANSFORMER project (761536)
