scope:

The present document studies inter-site and intra-site connectivity technologies, and how these can be used to realize the intra-site and inter-site connectivity services and fulfil networking requirements regarding VNF connectivity within the scope of NFV framework.

The present document also analyses the intra-site interactions on the [NF-Vi]/N reference point, network provisioning across network domain boundaries, OAM aspects for intra and inter-site connectivity, overlay and underlay network provisioning, and management and operations for connectivity services with recent traffic engineering technologies.

Finally, based on the analysis the present document provides a set of recommendations for enabling intra- and inter-site connectivity services within the NFV framework.
