Networks with Quality of Service (QoS) provisioning rely on QoS routing schemes to select paths between end-to-end hosts that can satisfy the requested service requirements. In this paper, the authors focus on networks that use a new service paradigm as a nested DiffServ model, which has been described as service vectors in combination with the Explicit End-point Admission Control (EEAC) scheme. The main objectives of service vectors are to improve the QoS granularity and service routing flexibility. These improvements enhance both network utilization and user benefits.
