Abstract:
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.
