why should it include a token?
orignal
btw need to check how we handle different ip address type in SSU
zzz
if charlie can send a token to alice with the agreement, then alice doesn't have to send a token request, and it saves one round trip
orignal
I see you mean token not relay tag
orignal
good point
zzz
I was also thinking, should hole punch be a real message instead of an empty message
zzz
or, we could send the token in a retry message instead of a new hole punch message
zzz
hole punch could be used for protocol identification, because what other protocol sends empty packets?
zzz
do you handle hole punch and start the handshake or do you ignore them?
