Responding to the Last Call for comments, I think the draft is well done and will be very useful in helping people understand what the CDNI effort is all about. My only substantive comment is that there is another use case related to IPv6 that could be spelled out under section 4.1, "Device and Network Technology Extension": The text for the additional use case could be: ---- 3. CDN-A only supports IPv4 within its infrastructure but wants to deliver content over IPv6. CDN-B supports both IPv4 and IPv6 within its infrastructure. CDN-A interconnects with CDN-B to serve out its content over native IPv6 connections. ---- In truth this could be seen as a variation of use case #1 in this section, "CDN-A cannot support a specific delivery protocol," and is similar to the reference to HTTPS in use case #1. However, when I read that use case I find myself thinking about higher level delivery protocols and not something as fundamental as IP. Plus, given that we'll be in the IPv4/IPv6 transition for some time, it may be useful to specifically highlight how CDNI could assist in the transition to IPv6. Again, I think it's a good document that should be published. My 2 cents, Dan P.S. Well, I will also admit that the comma in the first sentence of the abstract bothers me: "Content Delivery Networks (CDNs) are commonly used for improving the End User experience of a content delivery service, at a reasonable cost." I think that comma could be removed... but I'll leave that for the grammarians to duke it out... :-) On Jun 20, 2012, at 9:14 AM, The IESG wrote:
