NSPlacer: A Tool for Evaluating Service Placement Algorithms in Post-5G Networks
Résumé
Network Function Virtualization (NFV) has been a remarkable shift from dedicated network devices towards reusable Virtual Network Functions (VNF). A network service is defined as a set of VNFs connected via Virtual Links (VL), and it is realized by assigning its elements to their corresponding substrate network nodes and links. Efficient placement of the network services is one of the most important challenges introduced by NFV. We propose a demonstration of the "Network Service Placer (NSPlacer)" tool, as an implementation of several popular state-of-theart placement algorithms, to pave the way to study the placement problem for the researches in this field of interest. By being able to adjust various parameters, related to the substrate network, the service and the placement algorithm, our online tool provides nearoptimal and optimal results to serve as a comparison with many placement solutions.
