Hello Chairs and All,

Tom (new co-author) and I have worked out another revision and would like to get people's feedbacks on it. This version has quite changes in technical and editorial. Here are the key changes.

1)	Adapt the text of UDP checksum with IPv6 from the MPLS/UDP draft to fit in GRE/UDP. (Section 4.2)
2)	Adapt the text of Congestion Considerations from the MPLS/UDP draft (Section 6)
3)	Change the title to GRE-in-UDP encapsulation (was: Generic UDP encapsulation in IP Tunneling)
4)	Reorder the sections.
5)	Modify the text in applicability statement (Section 1.1)
6)	Modify the text for UDP checksum with IPv4 (Section 4.1)
7)	Modify the text for UDP source port (now same as the MPLS/UDP draft)
8)	Add Tom Herbert as co-author and Gorry Fairhurst as a contributor
9)	Various editing changes  

FYI: the MPLS/UDP draft is the draft-ietf-mpls-in-udp-11 that is in RFC editing queue now. Two drafts need to address the same issues as of a UDP application, the design term decided to work out mpls/udp first, and gre/udp.

Look forward to seeing your input here. 

Thanks,
Lucy

Abstract:
   This document describes a method of encapsulating network protocol
   packets within GRE and UDP headers.  In this encapsulation, the
   source UDP port can be used as an entropy field for purposes of load
   balancing, while the protocol of the encapsulated packet in the GRE
   payload is identified by the GRE Protocol Type. Usage restrictions
   apply to GRE-in-UDP usage for traffic that is not congestion
   controlled and to UDP zero checksum usage with IPv6.

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.
