                 5G-Datacenter Interconnection Use Case
           draft-defoy-nvo3-5g-datacenter-interconnection-00

Abstract

   Interconnection between 5G networks and datacenter networks provide a
   new use case for NVO3 and for the 3rd Generation Partnership Project
   (3GPP) "5GLAN" feature.  This document describes how layer-2 and
   layer-3 datacenter VPN technology can interoperate with anchor User
   Plane Functions (UPF) to interconnect 5G devices and datacenter
   servers over a virtual LAN.

1.  Introduction

1.1.  About the 5GLAN Feature

   In an ongoing work, 3GPP is seeking to enable LAN-like virtual
   networking between groups of end devices.  Appendix A provides
   references and additional details relative to the 5GLAN work.

   5GLAN requirements, defined in [_3GPP.22.261] can be shortly
   summarized as:

      A selected set of end devices can communicate with each other as
      if over a LAN, including over Ethernet or over IP, using a private
      addressing scheme.

      Unicast and multicast/broadcast communication is enabled between
      end devices, in some cases with a required latency (e.g. 180ms),
      or more generally a given consistent QoE.

      End device mobility is supported.

   General concepts and use cases were described in [_3GPP.23.734].

      In home and enterprise deployments, a goal of 5GLAN is to
      facilitate interworking with, and sometimes replacing, existing
      infrastructure, composed of fixed and wireless LANs.

      In enterprise deployments, 5GLAN will also provide a VPN-like
      service integrating mobile devices with enterprise networks.

      In industrial automation deployments, 5GLAN can enable low-
      latency, reliable and deterministic LAN traffic in manufacturing,
      machine control, packaging and printing use cases.

1.2.  Interaction between 5GLAN and Virtual Networks

   5GLAN connectivity does not have to be confined entirely within a 5G
