Inside DiffServ, the Assured Forwarding per hop behavior defines a service that guarantees the contracted target rate to the users and allows consuming more bandwidth if the network load is low. In this paper we perform an experimental study, whose key contribution is that current techniques and commercial equipment do not meet the goals of the AF PHB service in a scalable way.
