Hello,

I am replaying a message below that was originally posted on the routing-discussion
list yesterday. Follow-up discussion was then posted in two additional messages. The
messages are here:

http://www.ietf.org/mail-archive/web/routing-discussion/current/msg01949.html
http://www.ietf.org/mail-archive/web/routing-discussion/current/msg01950.html
http://www.ietf.org/mail-archive/web/routing-discussion/current/msg01951.html

I am cross-posting to transport area and int area now, because there seems to be
an overlap of interests with respect to UDP tunneling that may transcend traditional
area boundaries. Original message appears below; please post comments to the lists.

Thanks - Fred

Hello,

I am working on a spec for generic tunneling of any protocol over UDP, including
MPLS, GRE, IPsec, etc. The spec is called "AERO", and it includes:

  - an encapsulation format
  - a fragmentation and reassembly capability for MTU mitigation
  - a virtual link model
  - a control messaging mechanism
  - a routing and addressing system based on BGP

https://datatracker.ietf.org/doc/draft-templin-aerolink/

I understand that there have been discussions regarding protocol-specific
GRE and MPLS encapsulations within UDP, but I would like to offer up AERO
as a protocol-independent way of accommodating UDP encapsulations. I
also believe the routing system and other aspects of AERO should be of
interest to the routing area.

This work is derived from an earlier experimental RFC (RFC6706) which was
originally briefed to the routing area several years ago and published as an
AD-sponsored Individual Submission RFC. The current document can be
considered as a second edition of AERO, and the goal is to advance it to
standards track. Please send any comments or questions to the list.

Thanks - Fred
