Split Network Virtualization Edge (Split-NVE) Control-Plane Requirements
Abstract
In the Split Network Virtualization Edge (Split-NVE) architecture,
the functions of the NVE are split across a server and a piece of
external network equipment that is called an "External NVE". The
server-resident control-plane functionality resides in control
software, which may be part of hypervisor or container-management
software; for simplicity, this document refers to the hypervisor as
the "location" of this software.
One or more control-plane protocols between a hypervisor and its
associated External NVE(s) are used by the hypervisor to distribute
its virtual-machine networking state to the External NVE(s) for
further handling. This document illustrates the functionality
required by this type of control-plane signaling protocol and
outlines the high-level requirements. Virtual-machine states as well
as state transitioning are summarized to help clarify the protocol
requirements.
