Differentiated Services is a very promising approach toachieve quality of services in the Internet.However, settlingup static Service Level Agreements (SLA) between differentInternet Service Provider domains lacks flexibility andmay reduce quality of service as resource reservationscannot be adapted to the actual traffic.With the introductionof Bandwidth Brokers, a significant step towards acompletely dynamic Differentiated Services environmenthas been made.Bandwidth brokers negotiate and automatically Set up SLAs according to network load and provider policies.Nevertheless, this automatic set-up mayfail if there are bottlenecks in the network caused byphysical limitations or policy issues and may lead to congestion.In this paper, we propose a scalable mechanismto handle these congestion situations, that uses 4 phaseseach solving a different level of congestion. Our mechanismdoes not need any destination information thus makingIt applicable for the majority of Internet applications
