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

Yes, DiffServ itself is scalable, however, don't forget the 
management/control systems (e.g., bandwidth bokers etc.). Depending on the 
architecture, the services you want to provide, and the number of customers 
you want to service, the mgt systems might be a bottleneck.
