The IESG has approved the following document: - 'Network Virtualization Overlays (NVO3) Encapsulation Considerations' (draft-ietf-nvo3-encap-12.txt) as Informational RFC
This document is the product of the Network Virtualization Overlays Working Group. The IESG contact persons are Jim Guichard, Andrew Alston and John Scudder. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-nvo3-encap/ Technical Summary The IETF Network Virtualization Overlays (NVO3) Working Group Chairs and Routing Area Director chartered a design team to take forward the encapsulation discussion and see if there was potential to design a common encapsulation that addresses the various technical concerns. This document provides a record, for the benefit of the IETF community, of the considerations arrived at by the NVO3 encapsulation design team, which may be helpful with future deliberations by working groups over the choice of encapsulation formats. There are implications of having different encapsulations in real environments consisting of both software and hardware implementations and within and spanning multiple data centers. For example, OAM functions such as path MTU discovery become challenging with multiple encapsulations along the data path. The design team recommended Geneve with a few modifications as the common encapsulation. This document provides more details, particularly in Section 7. Working Group Summary Broad consensus on the document within the working group and issued raised seem to have been adequately addressed. Document Quality The document influenced choices made within BESS though as per the shepards write up, this did not require cross document review. Beyond that nothing of note. Personnel The Document Shepherd for this document is Matthew Bocci. The Responsible Area Director is Andrew Alston. _______________________________________________ nvo3 mailing list nvo3@ietf.org https://www.ietf.org/mailman/listinfo/nvo3
