[02:20:02] <craigt> Caching and policy enforcement in the enterprise use case. IWF etc.
[02:22:26] <craigt> As a content owner, we are approached by service provider networks to engage on various caching models for Media Delivery. Especially true where Metro to edge is charged by the bit...These include transparent, authorised or SPN CDN models

[02:25:10] m&m joins the room
[02:27:35] <hildjj> craigt: is that caching on behalf of the sender or the receiver?
[02:27:46] azet leaves the room
[02:28:07] <craigt> Mutually beneficial in many cases
[02:28:17] nwgh joins the room
[02:28:24] <craigt> QoS for content owner
[02:28:31] <hildjj> not who does it benefit.  who is paying for it?
[02:28:32] <craigt> financial for service provider
[02:28:52] <craigt> son
[02:28:55] <craigt> spn
[02:29:02] <craigt> typically
[02:29:17] <hildjj> so, not the content provider.
[02:29:26] <craigt> it represents a huge cost saving
[02:29:52] <craigt> with media traffic et al. no longer needing to go through policy enforcment and dpi platforms
[02:30:11] <craigt> as well as over wholesale purchased links
[02:30:25] <craigt> the cost/benefit stacks up very quickly
[02:30:42] <hildjj> but that's only for static media, right?  it doesn't work for realtime media?
[02:30:55] <craigt> live streaming also valid
[02:31:05] <craigt> which is pseudo static
[02:31:09] azet joins the room
[02:31:14] <hildjj> what about 1-1 live streaming with low latency, like phone calls.
[02:31:34] <hildjj> i can't see what help caching would provide for those.
[02:31:35] <craigt> main benefit is the 1:n
[02:31:42] <craigt> agreed
[02:31:56] <craigt> it's a bulk delivery issue
[02:32:03] <hildjj> As long as there are a number of people >1 on a given link that want the same content.
[02:32:13] <hildjj> (*exact* same content)
[02:32:47] <hildjj> including the same anti-piracy markings, e.g.
[02:32:54] <fielding> The easy technical distinction is that when a user agent uses a proxy it always sends an absolute URI as the request target, whereas when it does not know about a proxy it will send only the URI path.
[02:33:06] resnick leaves the room
[02:33:35] <craigt> Currently SPN all solve this differently...
[02:33:51] <craigt> and the content owner engages on demand (in the uk)
[02:39:12] Natasha Rooney leaves the room
[02:42:38] <=JeffH> SPN = Service Provider Network ?
[02:42:51] <craigt> Sorry, yes.
