The design team has updated this document based on comments we received
in the meetings and hallways in the Dallas.
I think the chairs are planning to ask for WG adoption, so it would be
good for folks to take a look at the draft.
The change log section summarizes the changes:
The changes from draft-rtg-dt-encap-01 based on feedback at the
Dallas IETF meeting:
o Setting the context that not all common issues might apply to all
encapsulations, but that they should all be understood before
being dismissed.
o Clarified that IPv6 flow label is useful for entropy in
combination with a UDP source port.
o Editorially added a "summary" set of bullets to most sections.
o Editorial clarifications in the next protocol section to more
clearly state the three areas.
o Folded the two next protocol sections into one.
o Mention the MPLS first nibble issue in the next protocol section.
o Mention that viewing the next protocol as an index to a table with
processing instructions can provide additional flexibility in the
protocol evolution.
o For the OAM "don't forward to end stations" added that defining a
bit seems better than using a special next-protocol value.
o Added mention of DTLS in addition to IPsec for security.
o Added some mention of IPv6 hob-by-hop options of other headers
than potentially can be copied from inner to outer header.
o Added text on architectural considerations when it might make
sense to define an additional header/protocol as opposed to using
the extensibility mechanism in the existing encapsulation
protocol.
o Clarified the "unconstrained TLVs" in the hardware friendly
section.
o Clarified the text around checksum verification and full vs.
header checksums.
o Added wording that the considerations might apply for encaps
outside of the routing area.
o Added references to draft-ietf-pwe3-congcons,
draft-ietf-tsvwg-rfc5405bis, RFC2473, and RFC7325
o Removed reference to RFC3948.
o Updated the acknowledgements section.
o Added this change log section.

Abstract:
The IETF Routing Area director has chartered a design team to look at
common issues for the different data plane encapsulations being
discussed in the NVO3 and SFC working groups and also in the BIER
BoF, and also to look at the relationship between such encapsulations
in the case that they might be used at the same time. The purpose of
this design team is to discover, discuss and document considerations
across the different encapsulations in the different WGs/BoFs so that
we can reduce the number of wheels that need to be reinvented in the
future.
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
