Demo: Automatic Deployment and Dynamic Scaling of NFV Service Chaining on Bare Metal (SCBM)

Network functions virtualization (NFV) based service chaining is one of the key enablers to speed up innovations of 5G networks for differential service needs in terms of network slicing. In this demonstration, we showcase automatic deployment of a service chain or slice (i.e., a load-balanced web-database system with memory cache), consisting of 4 different virtual network functions (VNFs) connected with proper mutual relations, on a x86-PC bare metal server running with Linux. Dynamic scaling-up of such a service chain without service interruption is also demonstrated by adding one more web server, during the run time, based on the fact that its relations with the others can be automatically copied and established. Our stress tests show the load*duration responses with the stress level before and after the scaling-up, and their difference becomes dramatically amplified as the stress level gets high.
