Please see response below Kevin: >>Wrt CDNI, what is it that draft-krishnan-cdni-long-tail-00 is proposing? >>The CDNI requirements (specifically META-14) already discuss distribution control policies, including preventing delegation. Beyond the ability to >>prevent delegation, are you proposing that CDNs be required to implement analytics-based delegation policies? That seems somewhat beyond our scope. Ramki: The CDNi req META-14 is about the selection of dCDN, but what long tail draft is proposing is the selection of uCDN the selection of uCDN by whom? based on the content attribute, i.e. whether the content is long tail personalized or not. The long tail draft also brings in the concept of no caching in the uCDN The intra-CDN decision of the uCDN to cache or not is generally outside the scope of CDNI. We are not disagreeing that the uCDN may elect to not cache some content (and in that case to not redirect to a dCDN), but this does not seem directly related to CDNI. and dCDN for certain types of content based on the content attribute, for e.g. long tail personalized content. The impacts of this on CDNi request routing is also explained. Can you summarize again very briefly the interaction you see between the desire to not cache some content and the CDNI interfaces? (when discussing Request Routing, please separate the impact you see on the Request Routing/Redirection interface vs Request Routing/Footprint & Cap Interface).
