Internet-Draft               NVO3 Use Case                 January 2017

1. Introduction

   Server virtualization has changed the Information Technology (IT)
   industry in terms of the efficiency, cost, and speed of providing
   new applications and/or services such as cloud applications. However
   traditional data center (DC) networks have limits in supporting
   cloud applications and multi tenant networks [RFC7364]. The goals of
   data center network virtualization overlay (NVO3) networks are to
   decouple the communication among tenant systems from DC physical
   infrastructure networks and to allow one physical network
