• Proposed name for the project: SDN distributed routing and VPN
• Proposed name for the repository: sdnvpn
• Project Categories: Collaborative Development

Many telecom network functions are relying on layer-3 infrastructure services, within a VNF between components, or towards existing external networks. In many cases, these external networks are implemented in MPLS/BGP technology in existing service provider wide-area-networks (WAN). This proven technology provides a good mechanism for inter-operation of a NFV Infrastructure (NFVI) and WAN.

This has lead to a number of activities both in OpenDaylight andOpenStack targeting to implement such functionality, including:

• OpenDaylight Project VPN Service: https://wiki.opendaylight.org/view/Project_Proposals:VPN_Service
• OpenStack Blueprint on Neutron API extension for BGPVPN:https://review.openstack.org/#/c/177740/
• OpenStack neutron project on bgpvpn: http://git.openstack.org/cgit/openstack/networking-bgpvpn

The proposed architecture in the VPN Service proposal both links NFVI networking services seamlessly into the WAN network architecture and provides a solution for distributed routing functionality in the virtual Switches using standard ODL southbound interfaces.

To assure integration into the NFVI, a collaborative project is needed, linking the work done in ODL and OpenStack on this item and assuring the integration of these functions into the OPNFV reference platform. A key objective is to validate the solution and to create visibility for that OPNFV has a viable solution.

Scope of the project is, in collaboration with the related projects in ODL and OpenStack, make sure that the functionality can be integrated on the OPNFV reference platform for the R2 delivery. Included in the scope are:

• Alignment of ODL Neutron NBI interface with OpenStack neutron API for BGPVPN, as soon as that is finalized
• Development of OPNFV R2 requirements on L3VPN reference implementation and related test cases
• Analysis and implementation of required OVS features to support performant distributed routing
• Identification of DC gateway reference platforms and functional requirements on them
