I am interested in knowing what are typical maximum sizes for IKEv2 messages
and UDP messages
in implementations.
The reason is that the IKEv2's spec has a must and a should being 1280 and 3000
bytes
respectively for IKEv2 messages, but does not have a maximum limit.
As you know some of the post quantum cryptographic candidates in our
standardization process
have large or very large public key , signature and/or ciphertext sizes.
My guess is that some updates to the spec and/or implementations would make
them work.
Your data points and discussions are appreciated.
