Abstract:
=C2=A0 =C2=A0The Open Caching working group of the Streaming Video Alliance= is
=C2=A0 =C2=A0focused on the delegation of video delivery request from comme= rcial
=C2=A0 =C2=A0CDNs to a caching layer at the ISP.=C2=A0 In that aspect, Open= Caching is
=C2=A0 =C2=A0a specific use case of CDNI, where the commercial CDN is the u= pstream
=C2=A0 =C2=A0CDN (uCDN) and the ISP caching layer is the downstream CDN (dC= DN).





Please note that it may take a couple of minutes from the time of submissio= n
until the htmlized version and diff are available at tools.ietf.org.

If there are specific reasons that it couldn't work using the existing metadata structure, it would be good to highlight that, as well as provided a more concrete definition of where these new objects would sit in the structural metadata hierarchy, what the serialization impact of that might be, and how backwards compatibility with RFC8006 might be affected. As a more general question: do we have any sense of whether or not folks are using or planning to use any of the proposed delegation methods (ACME STAR, subcerts, etc.); and/or do we have a feel for which methods might be most useful to CDNs? thanx. -- Kevin J.

My initial thought is that this is something better suited for a Control/Bootstrap interface, but if the request router addresses change over time, then perhaps FCI is the right place for it. Either way, I agree some discovery mechanism would be useful. For Fallback address, I don't see any issue with adding a new metadata object for this purpose. For Triggers regex, I think this falls into the same category as the URI Signing glob question Phil posed. We have the simple pattern matching because we originally thought regex would be too heavy, but if folks like regex, conceptually I don't see a reason why we couldn't add it (or replace the pattern match with regex). For Triggers playlist, a long time ago we decided to not deal with HTTP adaptive streaming to simplify the initial scope, but I think video and HAS awareness is probably necessary and worthwhile for us to re-address. I think I like content.playlists better than playlist.urls, but that's a detail. For Triggers geo-limit and scheduling, I think the concepts are useful. The implementation probably needs to be hashed out more, per the discussions in the working group meeting. I think it would be good to use these as a first implementation of trigger extensibility. In general, I like the idea of having something like generic-metadata for triggers. We didn't have a use case for it originally, but I think you have provided valid use cases therefor. For Relayed token auth, this one I have concerns about. I'm not sure how the security folks will feel about this, but I think if you and Phil could iterate on this, perhaps there's a reasonable solution to be found. For Logging, it would be unfortunate if the logging interface we specified had to be completely bypassed. If there is a need, then we should address it, but I would be interested in hearing from vendors on this. For CORS, I think this is an interesting topic and unfortunately we did not have time to talk about it in the WG session. I will be interested to hear thoughts from the rest of the WG on the proposals. It doesn't really have to be in CDNI, but it might be useful to have. thanx. -- Kevin J.

Hi Ori,

=C2=A0 (As an individual) For r= equest router address, I think you may want to consider a prioritized list = of endpoints.=C2=A0 My initial thought is that this is something better sui= ted for a Control/Bootstrap interface, but if the request router addresses = change over time, then perhaps FCI is the right place for it.=C2=A0 Either = way, I agree some discovery mechanism would be useful.

=
=C2=A0 For Fallback address, I don't see any issue with adding a n= ew metadata object for this purpose.

=C2=A0 For Tr= iggers regex, I think this falls into the same category as the URI Signing = glob question Phil posed.=C2=A0 We have the simple pattern matching because= we originally thought regex would be too heavy, but if folks like regex, c= onceptually I don't see a reason why we couldn't add it (or replace= the pattern match with regex).

=C2=A0 For Trigger= s playlist, a long time ago we decided to not deal with HTTP adaptive strea= ming to simplify the initial scope, but I think video and HAS awareness is = probably necessary and worthwhile for us to re-address.=C2=A0 I think I lik= e content.playlists better than playlist.urls, but that's a detail.

=C2=A0 For Triggers geo-limit and scheduling, I think= the concepts are useful.=C2=A0 The implementation probably needs to be has= hed out more, per the discussions in the working group meeting.=C2=A0 I thi= nk it would be good to use these as a first implementation of trigger exten= sibility.=C2=A0 In general, I like the idea of having something like generi= c-metadata for triggers.=C2=A0 We didn't have a use case for it origina= lly, but I think you have provided valid use cases therefor.

=
=C2=A0 For Relayed token auth, this one I have concerns about.= =C2=A0 I'm not sure how the security folks will feel about this, but I = think if you and Phil could iterate on this, perhaps there's a reasonab= le solution to be found.

=C2=A0 For Logging, it wo= uld be unfortunate if the logging interface we specified had to be complete= ly bypassed.=C2=A0 If there is a need, then we should address it, but I wou= ld be interested in hearing from vendors on this.

= =C2=A0 For CORS, I think this is an interesting topic and unfortunately we = did not have time to talk about it in the WG session.=C2=A0 I will be inter= ested to hear thoughts from the rest of the WG on the proposals.=C2=A0 It d= oesn't really have to be in CDNI, but it might be useful to have.
=

thanx.

Dear CDNI working group,
I have just submitted a draft for extension proposals for= CDNI,=C2=A0
These extensions are derived f= rom the work done within the Open Caching working group of the Video Stream= ing Alliance (SVA).
Open Caching is a speci= fic case of CDNI and therefore we are looking to standardized these extensi= ons and proposed new functionalities under the CDNI wg.

Looking forward to get fe= edback from the cdni group.

Best regards,
Ori

=C2=A0 =C2=A0CDNs to a caching layer at the ISP.=C2=A0 In that aspect, Open= Caching is

Dear CDNI working group,

   focused on the delegation of video delivery request from = commercial
   CDNs to a caching layer at the ISP.  In that aspect, = Open Caching is
   a specific use case of CDNI, where the commercial CDN is = the upstream
   CDN (uCDN) and the ISP caching layer is the downstream CDN = (dCDN).

HI Ori & Colleagues,

I do not see anything in the use case described in section 3.3 (scheduled o= perations) that requires the local time support the draft proposes.

What does local time give over and above the ability to pre-position by geo= graphic region, given that timezones are defined geographically?

Thanks
Ben

Dea= r CDNI working group,
I have just submitted= a draft for extension proposals for CDNI,=C2=A0
These extensions are derived from the work done within the Open Cachi= ng working group of the Video Streaming Alliance (SVA).
Open Caching is a specific case of CDNI and therefore we are l= ooking to standardized these extensions and proposed new functionalities un= der the CDNI wg.

Looking forward to get feedback from the cdni group.

I would expect so. I think of the playlist URL more as an optional optimization. Without this optimization, the uCDN would be using individual urls/patterns anyway -- though for prepositioning, patterns are trickier and the playlist becomes arguably more useful.

Ideal= ly, the uCDN would not attempt to send a playlist URL if the dCDN has not a= dvertised the playlist URL trigger capability.

>= ; Is the uCDN expected to fallback to producing a trigger request with the = URLs from the playlist enumerated as *.urls/*.patterns?

I would expect so.=C2=A0 I think of the playlist URL more as an optio= nal optimization.=C2=A0 Without this optimization, the uCDN would be using = individual urls/patterns anyway -- though for prepositioning, patterns are = trickier and the playlist becomes arguably more useful.
