The IESG has approved the following document: - 'Split Network Virtualization Edge (Split-NVE) Control Plane Requirements' (draft-ietf-nvo3-hpvr2nve-cp-req-17.txt) as Informational RFC This document is the product of the Network Virtualization Overlays Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-nvo3-hpvr2nve-cp-req/ Technical Summary In a Split Network Virtualization Edge (Split-NVE) architecture, the functions of the NVE (Network Virtualization Edge) are split across a server and an external network equipment which 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. Control plane protocol(s) 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. Working Group Summary The document was developed to provide input from the IETF community to help guide the development of extensions for VDP (VSI Discovery and Configuration protocol) that took place in parallel at the IEEE. The draft also describes how VDP is applicable to these split-NVE scenarios. There are no IPR declarations on the draft . Document Quality No concerns about the quality of the document. It represents WG consensus, and it has been widely reviewed and discussed on the list over a number of years. There was also close interaction between NVO3 and the IEEE during the development of the draft and VDP, including liaisons and presentations at NVO3 WG meetings by IEEE participants. Personnel The document shepherd is Matthew Bocci (matthew.bocci@nokia.com). The responsible Area Director is Alia Atlas (akatlas@gmail.com).
