In this paper we present a new mechanism to provide an assured service in terms of target rate and fair excess bandwidth, like the Internet Assured Service. Research in Internet Assured Service faced up both questions in separate ways proposing different traffic conditioners to work with the RIO buffer management, and proposing different modifications to this buffer management, among others. In this work, we suggest using a buffer management scheme different from RIO that also treats in-of-profile and out-of-profile packets differently but avoiding interference between them. This scheme is used together with the Counters Based traffic conditioner because of its high accuracy in guaranteeing target rates. We evaluate and compare by simulation the performance of our proposal using TCP RENO sources. One important issue to be considered is that the proposal is a feasible alternative to the standard architecture for Differentiated Services in Internet.
