RFC 8151 NVO3 Use Case May 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 goal of data
center Network Virtualization over Layer 3 (NVO3) networks is to
decouple the communication among tenant systems from DC physical
infrastructure networks and to allow one physical network
infrastructure to:
o carry many NVO3 virtual networks and isolate the traffic of
different NVO3 virtual networks on a physical network.
o provide independent address space in individual NVO3 virtual
network such as Media Access Control (MAC) and IP.
o Support flexible Virtual Machines (VMs) and/or workload placement
including the ability to move them from one server to another
