Hi Tom,One question that may have been discussed before. What if we directly use UDP-Lite to encapsulate GUE? Then the checksum in UDP-lite could provide similar function as the checksum option you defined. RegardsLizhong---------- Forwarded message ----------This draft is based on feedback from Honolulu. This adds a checksum option in GUE that should hopefully be adequate to protect against address corruption when using zero checksums with UDP over IPv6. Also, made it UDP-lite like so that some portion of payload can optionally be checksummed. Comments are appreciated. Thanks, Tom ---------- Forwarded message ---------- From: <internet-drafts at ietf.org> Date: Wed, Nov 26, 2014 at 2:42 PM Subject: New Version Notification for draft-herbert-guecsum-00.txt To: Tom Herbert <therbert at google.com> A new version of I-D, draft-herbert-guecsum-00.txt has been successfully submitted by Tom Herbert and posted to the IETF repository. Name: draft-herbert-guecsum Revision: 00 Title: Checksum option for Generic UDP Encapsulation Document date: 2014-11-26 Group: Individual Submission Pages: 8 URL: http://www.ietf.org/internet-drafts/draft-herbert-guecsum-00.txt Status: https://datatracker.ietf.org/doc/draft-herbert-guecsum/ Htmlized: http://tools.ietf.org/html/draft-herbert-guecsum-00 Abstract: This specification defines the Generic UDP Encapsulation (GUE) checksum and an associated header option. This checksum covers the GUE header, IP addresses, UDP ports, and optionally all or part of the encapsulated payload. It provides verification of protocol header elements, and is particularly relevant in the case where the UDP checksum is set to zero. 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. The IETF Secretariat
