Colleagues,

We have posted a new version of the CDNI Problem Statement, which can be found here:
http://tools.ietf.org/html/draft-jenkins-cdni-problem-statement-02

A diff from the -01 version can be found here:
http://tools.ietf.org/rfcdiff?url2=draft-jenkins-cdni-problem-statement-02.txt

A summary of the changes:
- Changed "API" to "protocol" following some private comments
- Included the 3GPP/MPEG text from Ali C. Begen & Ye-Kui Wang with some minor grammar/referencing changes
- Included the definitions for dynamic & pre-positioned content & metadata acquisition updates as discussed on the mailing list.
- Added a paragraph on data type/object naming & referencing with reference to draft-jenkins-cdni-names
- Added paragraph that uses draft-bertrand-cdni-experiments to show that the problem space is real & existing CDN technology is not sufficient to address it.
- Expanded text under "Request-Routing API" to try convey that it may cover both a "per-request" type of query as well as dynamic routing info specifically for request routing.
- Expanded the Reference model ASCII art to show "request API" between user-agent and CDN Request Routing System and added a bullet item for this under the list of items outside the scope of CDNI
- Moved "content Purge" and "Preprovisioning triggers" under the "CDNI Control API" (instead of under Metadata distribution).
- Changed Metadata API/protocol to Metadata distribution protocol as that better describes its function.

Looking forward to your comments & discussing it further in PRague.

Ben
