  1. Discussion Issues on Receiver Access Control in the Current Multicast Protocols(Update)draft-ietf-mboned-rac-issues-01.txt November 9th, 2005 Tsunemasa Hayashi (hayashi.tsunemasa@lab.ntt.co.jp) Haixiang He (haixiang@nortelnetworks.com) Hiroaki Satou (satou.hiroaki@lab.ntt.co.jp) Hiroshi Ohta(ohta.hiroshi@lab.ntt.co.jp) Susheela Vaidya (svaidya@cisco.com)

  2. Introduction Key Point: In our experience, many issues raised in the I-D are NOT currently well covered by existing standards. Goal: In multiple-entity networks, • to achieve the same capabilities such as access control & accounting used in unicast content delivery while taking advantage of multicasting’s resource efficiencies • To achieve admission control

  3. Network models MULTIPLE ENTITY MODEL SINGLE ENTITY MODEL Content provider (CP) and network provider (NP) functions are realized by one company Content providers and the network providers are different companies Content Provider A Content Provider N Content provider function AAA AAA Network provider function AAA Multicasting QoS Mgt Network ProviderA edge edge Multicasting and QoS Mgt edge edge Hosts / Users A user subscribes to only one CP (NP) Hosts / Users A user may subscribe to more than one Content Provider

  4. Major Changes • updated draft-hayashi-rac-issues-01.txt to draft-ietf-mboned-rac-issues-00/01.txt based on WG comments. • remove unnecessary overlap with the requirement draft (draft-ietf-mboned-mac-req-01.txt) • 4.1 Access limits and resource issues • 4.3 Capability to distinguish between users • change the title of 5.2 to clarify the method • “IGMP/MLD plus L2/L3 Authentication with Access Control Policy “ • add detail description to “IGMP/MLD with unicast control “ in 6.1 • malicious users may send join in disregard of unicast control • add detail description to “L2/L3 authentication with access control policy” in 6.4 Maintain guaranteed QoS • NW login/out based QoS control, not stream request based (Continued on next slide)

  5. Major Changes (continued) • remove 6.8 “Triple Play capability, compared by architecture” • Capability of triple play is independent of architecture. • add 6.8 “Comparison summary ” • To clarify arguments of this I-D • add draft-ietf-mboned-mac-req-01.txt to “Normative References”

  6. Issues with current architectures • Current architectures do NOT fully cover requirements (yes=satisfies the major requirements)

  7. CONCLUSION Key Point: - Currently many operational issues raised in the I-D are NOT perfectly covered by existing standards. Goals: • In multiple-entity networks, • to achieve same operational capabilities such as access control & accounting used in unicast content delivery while taking advantage of multicasting’s resource efficiencies • To achieve admission control capabilities. Next Steps: • To update this I-D reflecting comments in ML and this meeting -To start discussion on multicast AAA frameworks for multiple-entity networks.
