AMT draft status:
Joel Ja- AMT is close, only nonce discuss to review proposed text
BCP draft preso (Percy Terapore):
Chairs - Will work with authors to coordinate outreach to operators for feedback
Joel Jaglie- Change ‘AD’ to ‘Admin Domain’ if you want this to move faster
Stig Venaas - send to NOGs
Mike McBride - Have you presented at nanog? But we work with operators and this is really good .
Percy Terapore - will change AD to admin domain
Chair - Any feedback from security?
Michael Abrahamsen - mcast for 10 years. Lots of protocols to mcast running. here’s list of more protocols to operational reqs. It’s already operationally hard. Even LDP req for MPLS is a bit much. Setting up PIM and MSDP etc is already complex. There a tendency to invent new stuff which is operationally hard
Bill Attwod - the original proposal suggested changes to IGMP which was too much to ask.
Stig Venaas - I don’t understand all of the security protocols 100%. This seems to make sense from a protocol point of view. Is this the right way to solve this? This is also in PIM. This does have benefits compared to the early proposals. Do we need to protect content, restrict access or restrict distribution
Bill Attwood - If ACL is enough then this isn’t needed
Stig Venaas - shared medium could distribute content to non-authenticated users
Bill this doesn’t protect that case
- there’s a whole group missing from your diagram, switches
Bill Attwood - I’m aware of this issue, but haven’t yet explored.
Michael Abrahamsen - when you invent something new you need some spoofing protection - back to the shared medium issue. Some people provision ACLs for mcast distribution
Bill Attwood - for IPTV, ACLs are implemented based on purchased agreements
Toerless Eckert - love to hear from operators that this solution solves problems they have
Michael Abrahamsen - Is this tied to SPRING
Ice Wjiands- There are some similarities, but there are no SPRING procures we depend on for SPRING
Michael Abrahamsen - Its more of an operational question, its not much different
Dino Farinacci - I think what your saying is Spring has a new paradigm for both Uni and Multi, are you asking the BIER people to just use SPRING?
Michael Abrahamsen - When you’re telling people about it, it could benefit to tell them about it at the same time.
Ice Wjiands - Spring is source routing which is effectively impossible for multicast.
