A flexible and distributed architecture for adaptive end-to-end QoS provisioning in next-generation networks

摘要

In this paper, a novel distributed end-to-end quality-of-service (QoS) provisioning architecture based on the concept of decoupling the end-to-end QoS provisioning from the service provisioning at routers in the differentiated service (DiffServ) network is proposed. The main objective of this archi- tecture is to enhance the QoS granularity and flexibility offered in the DiffServ network model and improve both the
