Be Scalable and Rescue My Slices During Reconfiguration

Abstract : Modern 5G networks promise more bandwidth ,less delay, and more exibility for an ever increasing number of users and applications, with Software Defined Networking. Network Function Virtualization, and Network Slicing as key enablers. Within that context, effciently provisioning network and cloud resources of a wide variety of applications with dynamic users' demands is a rea lchallenge. In this work, we consider the problem of network slice reconfiguration. Reconfiguring regularly network slices allows to reduce the network operational cost. However, it impacts users' Quality of Service by changing the routing. To solve this issue, we study solution simplementing a make-before-break scheme. We propose new models and scalable algorithms ( relying on column generation techniques) that solve large data instances in few seconds.
