Talk Title: Multi-objective Optimization for Service Chaining

Abstract:

To cope with high capacity and low latency requirements of 5G services, the service function chains placement problem is solved, for the first time, by the multi-objective optimization approach combining the virtual layer, IP layer, and optical layer. We approximate the Pareto-fronts and propose a weighted-sum algorithm as a building block for 5G management and orchestration architecture by interacting with the NFVO (e.g., OSM). Both simulation and experiment are conducted over a real testbed composed of multiple OpenStack deployed servers interconnected via optical fibers. Results prove that our algorithm can optimize resource usage in multi-access edge computing nodes under diverse workload scenarios while maximizing service acceptance rate.
