Comments regarding scalability issues with STUN/TURN/etc...

Hi everyone, it has been awhile since I last posted.

 

These were some items posted to a common list for VoIP which I responded
to regarding considerations that should be made for any protocol being
used to address traversal of VoIP via middle boxes (in this case
firewalls).

 

Statements have been made that the solutions mentioned in the title
provide scalability over the emerging session border controller
technologies. 

 

Also the latest draft by Melinda brought up some additional points with
direct statements naming a couple of these vendors. I would like to
bring this discussion up a bit more to investigate the true scalability
factors.

 

I believe that we do need an IETF solution to the problem at hand that
does not present yet another issue to the mix, and that the current
protocol proposals need to consider scalability factors for a number of
reasons.

 

Let the attachments be a start to the discussion, while I formally write
up some more examples, which were between me, Johnathan, and Jiri.

 

Thanks in advance,

Chris
