Zusammenfassung:	The paper presents integrated mechanisms for differentiated service (DiffServ) architecture consisting of active rate management (ARM) at the edges of the network and two-color active queue management (AQM) controllers at the core of the network. The AQM controller is a robust linear quadratic regulator based proportional-integral-derivative controller for two-color marking at the core. The proposed mechanism is for DiffServ assured forwarding per hop behavior for guaranteeing minimum rates for exact and over-provisioned systems. The performance of the proposed scheme is evaluated and compared with other approaches using the NS-2 simulator.
