Federation of Cross-Domain Edge Resources: A Brokering Architecture for Network Slicing

Abstract

We present an architecture enabling a network operator to federate IT and network resources owned by private third-party actors located at the edge of the network. The cornerstone of this architecture is a brokering layer that relies on a graph-based resource database. The brokering layer contains all the necessary functions allowing such federation: exposure of cross-domain resources towards network operators and their qualification for deployment and provisioning. We have implemented a Proof-of-Concept of the proposed architecture which we illustrate through the federation of a Stadium infrastructure resources and then through the on-demand creation and deployment of end-to-end network slices over multiple domains for event services. Finally, we present and discuss performance evaluation results.
