Multi-Domain Orchestration Of 5g Vertical Services And Network Slices

This paper presents an orchestration framework for the delivery of 5G vertical services and end-to-end network slices in a multi-domain scenario. The proposed architecture relies on a business model where verticals and service providers take the roles of digital service consumers, digital service providers and network service providers, each acting in its administrative domain. The interactions and delivery procedures among these entities leverage on standard solutions for interfaces and information models defined by ETSI and 3GPP. The paper also presents proof-of-concept applications of the proposed architecture in two H2020 European research initiatives.
