1. 1 IPv6 Multicast Technology Protocols: multicast BGP PIM Sparse Mode and PIM-SSM Multicast Listener Discovery (MLD) - replaces IGMP IGMPv2 == MLD IGMPv3 == MLDv2

2. 2 IPv6 Multicast Technology ASM - Any Source Multicast what you’re used to in IPv4 but... no MSDP?! one global Rendezvous Point (RP)

3. 3 IPv6 Multicast Technology SSM - Source-Specific Multicast the next big thing in IPv4 and IPv6 source is discovered out of band limited OS and application support Cisco DNS mapping - a useful hack, for now

4. 4 IPv6 Multicast Technology Embedded-RP only possible with v6’s huge addresses RP is encoded in the group address no stack or app support needed to be turned on... soon? requires pre-planning for your RP address still in draft

5. 5 Current Status The m6bone RP and main tunnel router at RENATER tunnels to lots of places mostly software-based routers and PCs

6. 6

7. 7 But we need Native! Tunnels have lots of problems: encap/decap hits router CPU tunnel overhead adds to b/w use tunnels concentrate the utilization, mostly defeating the point of multicast lots of points of failure

8. 8 Progress on native connections GÉANT SURFnet, SWITCH, GRnet, FCCN, NORDUnet, RedIRIS, HUNGARNET, GARR UNINETT, FUNET, CESGA, CESCA Endpoints - Østfold University College, SWITCH, UNINETT RedIRIS (and probably others) Abilene NYSERNet, Merit Endpoints - NYSERNet Office, NYU, I2 Ann Arbor

9. 9 Demonstration Setup Office 7609 Syracuse 7609 NYC 12410 LAN 6500 Edge 7600 Abilene NYCM T640 to WASH NYSERNet SyracuseNYU

10. 10 Demonstration Setup HP switch Internet2 M10 Abilene IPLS T640 Merit Juniper Abilene CHIN T640 to NYCM Internet2 Ann Arbor

11. 11 Demonstration Setup Extreme switch Meeting M320 Abilene WASH T640 Member Meeting - Philadelphia Force10 switch

12. 12 Demonstration Sources NYSERNet Syracuse Mac desktop, DVTS with external DV converter, analog camera New York University Mac Mini, VideoLAN with stored video Internet2 Ann Arbor WinXP PC, Conference XP with camera Mac Mini, DVTS with DV camera

13. 13 Bumps in the Road limited experience - network engineers, vendor support, application developers limited toolset - loss testing, fault isolation everything is new everything is recent equipment limitations, bugs, incomplete features

14. 14 Bumps in the Road switch flooding - this is a big one! But help is coming, and things will get better as we add more endpoints (hint, hint!)

15. 15 Why? to build experience and expertise to drive features and fixes to encourage developers to add support because IPv6 won’t be accepted if it can’t do multicast because we can! and someday soon we’ll need to...
