QoS Technology of Ethernet-based IP Access Network
Zhi Li · 2006
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- cess 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 ar- chitecture for support of dynamic and per-session QoS control over Ethernet-based IP access network is discussed, mo- reover the QoS-related control interfaces and their requirements are briefly introduced.
