Hello, This is version 5 of the GUE draft.
Most of the changes are clarifications based on Bob Briscoe's in-depth review. Some highlights: - Added a terminology section - Clarified that ports are set either for connection semantics or for source port entropy - Added motivation for random access of flags and fields - Added an example of a GUE header with fields - Clarified definitions of data messages and control messages - Added reference to TOU about details of L4 encapsulation (need to update TOU draft now) - Adding diagrams to show how a received packet is reinjected for protocol processing - Added references to STUN and ICE in NAT discussion - Added reference to RFC6438 in discussion about methods to get flow entropy - Added "Benefits of GUE" section to motivations - Added bit to security field (discussion with Lucy) by moving checksum bit to end of allocated ones. Need to update extensions and GUE security for this. - Added guidelines about paramter negotian - Fixed references Our intent is to move GUE to be a WG item in int-area since it is a generic protocol not really nvo3 specific. After Berlin IETF there was call to take it up in int-area, however we didn't get official acknowledgment of it being a WG item. Once we have that I assume the draft name will change to reflect that. Comments and review are greatly appreciated!
