NGN (Next Generation Network) architectures are constantly evolving towards solutions that allow the operator to provide QoS-guaranteed services in heterogeneous, multi-domain and multi-services networks. In this context, DiffServ-aware Traffic Engineering (DSTE) is one of the most advanced technologies, which performs Traffic Engineering (TE) in a differentiated service environment by applying routing constrains with class granularity. This approach requires the definition of an efficient bandwidth constraint model to allocate the available link resources in a per Class Type (CT) basis, which influence both resource utilization and provided QoS.
