Pretty much everything in ipv6 will be over the MTU... on ipv4 we disabled this because when you talk to things that don't speak TCP you have a packet over the MTU you try TCP it times out in 30 seconds then you send it anyway via UDP. So why have a 30 seconds timeout when you don't need too. /b On Dec 15, 2008, at 2:06 PM, Kristian Kielhofner wrote:
I thought (for the user) it might make sense to just force TCP. It might make sense to set TCP explicitly (less back and forth). However, keep in mind the higher overhead of TCP in the first place. I guess it would depend on what's in the body (obviously). Messages with smaller bodies (SDPs, etc) might eek through with UDP while those with larger bodies may have to requeue for TCP.
