The Differentiated Services (DS) framework is one of the basic architectures that have been proposed for provision in the Internet. One of the most significant advantages of DS is ability to distinguish management plane of the network to provide the customer Quality of Service. A DS architecture proposed by IETF alone is not sufficient to address the end-to-end guaranties in a network layer but it does show great potential for scalability. To fulfill negotiated QoS services Bandwidth Broker - an additional management entity, has to be implemented. The main tasks of the Broker are: limiting the traffic volume carried through the managed domain and services nego-tiation on behalf of domain with customers and adjacent brokers. The authors concentrated on the concept of distributed Broker as a more scalable and efficient solution. The different bandwidth allocation scenarios are presented and compared with regard to signaling overhead, admission control delay and control complexity. The quota-based admission control algorithm has been briefly described and discussed. The new style of reservation has been proposed to decrease the amount of signaling traffic between core and edge routers. The example of its functioning has been given at the end of the presented paper.
