This work presents a bandwidth management mechanism to be used with mapping mechanisms between Integrated Services (IntServ) and Differentiated Services (DiffServ) domains. The mapping mechanisms have a dynamic nature and are associated with the Admission Control functions such that the state of the network is reflected in the admission decisions of new IntServ flows into the DiffServ network. The work is focused in the mapping between the IntServ Controlled-Load (CL) service and the DiffServ Assured Forward (AF) Per-Hop-Behaviour group. The proposed bandwidth management mechanism evaluates the bandwidth needs of the AF classes in the DiffServ domain taking into account the behaviour of the previously mapped CL flows for the same IntServ destination network. The results obtained by simulation show that the mechanism improves the use of the available bandwidth for a given AF class. The mapping mechanisms detects Quality of Service (QoS) degradation occurrences and once detected the control mechanism allows the reestablishment of AF Class QoS.
