anything that should be added/modified (or just edit the etherpad). In
particular, if anyone has notes from Jake and Lorenzo's sections, that
would be great.

Agenda un-bashed
multicast-yang-model:
Sandy: Waiting on Jakes review, Jake apologized and will send by
next week

- should be done after addressing the last DISCUSS and few comments.
draft-ietf-mboned-multicast-telemetry
Mike McBride, 10 min
- Jake: do you need recommendations about scalability for the apps
handling multicast telemetry data?
Mike: maybe, good comment. well look into adding something.
EUMETSATs Use of Multicast over the MBONE
Oriol Espanyol, 30 min
Lenny: whats the encryption/authentication like?
Oriol: usb key to unlock some restricted data, done after file is
fully received.
Tim: Its the end site or the NRENs that wont multicast?
Oriol: Typically the NRENs, but GEANT is doing it well. We use GRE to
bridge, with some pain for setting up.
Jake: how many users?
Oriol: 4.5k for the satellite thing started 20 years ago. Few users
for the internet paths/terrestrial links, but we think in the future it
will only be available this way.
Lenny: what about unicast/CDNs? How much do you need this to be
multicast?
Oriol: data is very dynamic, the CDN data replication model does not
make as much sense, because its only useful during a certain window. cost
of multicast link is much lower than alternatives. Internal evaluations of
cost is that multicast is fixed cost regardless of user count, but
satellite capacity is very expensive, so were moving to the similar
concept with a fixed cost regardless of number of users. The multicast
approach is an order of magnitude less.
