Re: [Diffserv-interest] size of a DiffServ domain

If that is the question, I think the answer will be "as large as possible". 
I haven't seen any simulations yet that seemed to be large enough to 
capture the edge-to-edge behaviour of a real network (tens or hundreds
of border routers and thousands of clients).
