[13:12:06] <joel jaeggli> draft-zhang-mboned-multicast-service-yang-00
[13:14:12] <joel jaeggli> comments?
[13:14:30] <joel jaeggli> stig - question about the transport?
[13:14:47] <joel jaeggli> can you use multiple stransports for this s,g
[13:15:20] <joel jaeggli> percy - in general the concept of yang model is good
[13:15:50] <joel jaeggli> since this is a general yang model that you can use and then modify or do we need one specifically for multicast
[13:16:02] <joel jaeggli> zhang - maybe l3sm?
[13:16:26] <joel jaeggli> shibon lu ? -
[13:17:11] <joel jaeggli> what's the relationship bewteen this and the l3sm?
[13:17:39] <joel jaeggli> zhang - this model is generalized
[13:17:53] evyncke joins the room
[13:20:25] <joel jaeggli> lu - providers don't want vendors to define their service model
[13:23:07] <joel jaeggli> sjshep - do we have a yang docotor assigned to this SM?
[13:23:14] <joel jaeggli> gjshep?
[13:24:04] <joel jaeggli> next is percy
[13:24:36] <joel jaeggli> presentation use of multicast  across interdomain peering points
[13:30:56] <joel jaeggli> shep - show of hands on reading the draft
[13:31:07] Christian Hopps joins the room
[13:31:36] <joel jaeggli> stig - you still talk about asm as well?
[13:31:51] <joel jaeggli> percy - there are competing views
[13:33:01] <joel jaeggli> gjshep - we'll get the usuals suspects on board
[13:33:30] <joel jaeggli> charlie perkins - presentation multicast consideration over ieee 802.11
[13:34:20] cjbc joins the room
[13:41:08] <joel jaeggli> dino - does the mean the ap doesn't forward the broadcast?
[13:41:30] <joel jaeggli> charlie - the intention is to not wake up the station
[13:41:39] <Christian Hopps> hmm audio died
[13:42:10] Christian Hopps leaves the room
[13:44:12] Christian Hopps joins the room
[13:45:08] <Christian Hopps> restarted firefox and rejoined, audio still dead.
[13:45:49] <Meetecho> fixing that
[13:46:16] Nigel Bragg leaves the room
[13:46:24] Nigel Bragg joins the room
[13:48:31] <joel jaeggli> dino - what mac address do they resolve with?
[13:48:51] <joel jaeggli> chairle no engineering arp sponging right now
[13:49:25] <Meetecho> in the meantime (restarting streamer) the mp3 feed is live
[13:50:28] <joel jaeggli> related wg topics
[13:50:38] <Meetecho> audio back
[13:50:43] <joel jaeggli> intarea mboned 6man pim
[13:53:37] <joel jaeggli> dino - did IEEE consider running a solution a three decade old protocol between bsses and stations
[13:54:06] <joel jaeggli> dorothy stanley - directed multicast reqires cahnges but the ap and the station
[13:54:40] <joel jaeggli> in vendor specific implementions the decision is on the ap only
[13:55:15] <joel jaeggli> dms provides a facility for the station to request this
[13:56:15] <joel jaeggli> the discuss yesterday was very productive and a number of additions will ensue
[13:56:35] <joel jaeggli> neighbor discovery extensions may require l2 knowledge
[13:57:08] <joel jaeggli> dino - to make the arp proxy stuff work the sending station should unicast it
[13:57:45] <joel jaeggli> dorothy - traffic on a dot.11 system is only multicast from the station not the client.
[13:57:58] <joel jaeggli> greg- handing over to pim
[13:58:06] <joel jaeggli> welcome to the pim working group

[14:08:24] <joel jaeggli> dino - did you consider advertising specific sources to reduce the amount of state e.g. subnet,g
[14:09:22] <joel jaeggli> stig - how many people have read this draft?
[14:09:30] <joel jaeggli> ok great   few
[14:09:41] Anish Peter joins the room
[14:10:08] <joel jaeggli> dino - do it as a seperate protocol, modify the igp to advertise subnets as multicast capable
[14:11:13] <joel jaeggli> dino - you do have a mapping database you can use so that they don't have to be flooded
[14:15:49] Anish Peter leaves the room
[14:16:02] <joel jaeggli> alvaro -
[14:16:11] <joel jaeggli> stig - we'll take it to the list

[14:18:00] Anish Peter joins the room
[14:28:28] <joel jaeggli> stig - thanks for work on this  
[14:28:49] <joel jaeggli> there are a handfull of vendors on the design team
[14:29:13] <joel jaeggli> it might be that you implementation doesn't work with this  so it's good to take a look
[14:29:21] <joel jaeggli> have you tried to get review of this

[14:38:02] <joel jaeggli> plus the authros
[14:38:24] <joel jaeggli> people in the dt are probably in favor
[14:38:49] <joel jaeggli> we should consider adoption as this is something we need.
