IETF99 Bits-N-Bites demonstration on Multi-Provider NFV solution

A highly relevant proof of concept demonstration at the Bits-N-Bites session on 20 July 2017 at IETF99 (Prague, Czech Republic) by the EU 5GExchange project  on a Multi-provider NFV over IP BGP-VPN, IP/MPLS, PCEP, OpenFlow SDN, OpenStack and Docker technologies.

In this demonstration, we are showcasing a multi provider NFV orchestration system with a special focus on network services over mixed IP/MPLS and OpenFlow SDN networks. The system allows providers to offer end-to-end network services with VNFs operated by different service providers in heterogeneous technology and resource environments. We propose a new hierarchical orchestration architecture that, on one hand, builds on existing state of the art components from industry and standardization, and on the other hand, innovative in lifecycle integration and operational policy handling. The orchestration system is designed with special focus to enable a coopetitive 5G service ecosystem where VNFs and their operational components may be developed by or operationally belong to 3rd parties. These VNF as a Service (VNFaaS) components are also available for partner providers to accelerate their NFV Infrastructure offerings. We emphasize the growing importance of multi provider orchestration (federation) to exploit the potential of edge/distributed cloud for Industry 4.0. Our network service orchestration is fully automated and takes into account latency and redundancy requirements when selecting the deployment locations for the service components.

The current research prototype demonstrates a situational orchestration hierarchy with different primary providers for different customers, interworking of IP VPN and OpenFlow SDN based service components and the ability to reuse shared network functions depending on provider policies and 3rd party’s service policies. For the IP VPN part, we use the vPE concept implemented in OpenStack through the BGP VPN API and the BagPipe driver. Then this IP VPN is carried in the IP/MPLS backbone through dedicated RSVP-TE tunnel instantiate through OpenDayLight SDN controller by mean of PCEP protocol.

The work is part of the 5G Exchange European Union collaboration project ( and the shown components are developed within Ericsson Research (Cloud and SW Technology), Orange Labs and the Budapest University of Technology and Economics.
