| Abstract: | QoS mechanism in access network is a key factor to end-to-end QoS guarantee of NGN, and Ethernet pre dominates in the access network.. This paper discusses the study on QoS control architecture for Ethernet based IP ac eess network of ITU NGNFG. The definition of Ethernet-based IP access network and the reference architecture are firstly introduced,then the QoS problem of Ethernet-based IP access network is analysed,and then the QoS control architecture for support of dynamic and per-session QoS control over Ethernet based IP access network is discussed,moreover the QoS-related control interfaces and their requirements are briefly introduced. |
