2. NTT 2005 © 2 Introduction Major requirements for multicast AAA –draft-ietf-mboned-maccnt-req-01.txt Access Control for Multicast Packets Bandwidth Resource/ QoS Management for NP Cooperation between NP and CP for accounting Distinguishing Users or Receivers for Accounting Fast Join and Leave Issues related to current multicast AAA architectures –draft-ietf-mboned-rac-issues-01.txt Current architectures do NOT fully cover above requirements for multiple entity network A new framework for multiple-entity NW is needed

NTT 2005 © 3 NP (B) Functional Roles of Multiple-Entity Networks CP is responsible for authentication of content request NP’s edge routers control multicast packets and collect Join/Leave based accounting information NP is responsible for packet level QoS (if necessary) edge NP (A) NNI CP (A) AAA Server CP (B) AAA Server Authentication Multicast Control Accounting QoS management NP= Network Provider CP= Content Provider User ex. Fixed line access ex. Mobile access UNI User

5. NTT 2005 © 5 Conclusion Start to discuss multicast AAA frameworks for the multiple-entity networks. Desire feedback from WG Wish for acceptance as WG item
