Hi Fred, Change the GUE header to treat the first nibble as a next header selector. 4 means IPv4, 6 means IPv6 and X means GUE. [Lucy] As I mentioned in several previous mails, I don't think that this is a good design for GUE. Even if a compression is required, the solution SHOULD use a separate UDP port to indicate IP first and then check the first nibble for IPv4 or IPv6, which, in fact, is the IP-in-UDP proposal.
However I agree with Tom that the compression concept does not align with GUE principal. GUE encapsulation should not assume IP payload in first place!
