Dear all, Draf 08 was just submitted. Thanks goes to all the reviewers and commenters. As a general note, we have removed the option to advertise an IPv4 / IPv6 address in both redirect target and fallback target and left only the CNAME option. The reason is that in the CDNI docs there is only reference to CNAME option for DNS routing, not AAAA/A records, and this is also aligned with Open Caching specification. Fixes list by commenter: *Alissa Cooper* + EDNS0 client-subnet - a note was added to new section 2.1 regarding the privacy drawbacks and reference to guidance in RFC 7871. *Roman Danyliw* + EDNS0 client-subnet - see comment above. + Add references to SVA and Open Caching - added to the introduction + Typos - all fixed. *Alvaro Retana* + Add references to SVA and Open Caching - added to the introduction *Éric Vyncke*+ Router definition - Request Router definition added to section 1.1 + Switching / preserving of URI scheme - we have added a "scheme" property to the redirect target object, to determine if the scheme is preset or to be the same as the original request (if the property is absent) + Expand FCI in Abstract - done + Requirement Langague - moved to the introduction + Typos - all fixed *Benjamin Kaduk* + Geo DNS reference - there is no RFC or other official standard, instead we have added a short explanation of that we mean by "Geo DNS" + The dCDN's advertisements interaction with the uCDN's DNS redirection decision - we have elaborated more about how uCDN is expected to use the dCDN advertisement + Change reference from section 5 of RFC8008 to sections 5.1 and 5.2 of the same - accepted and done + IP address examples - see first comment in this email, we have removed the options to route to IP addresses and left only CNAME + Redirection to TLS - we have added "scheme" property to the Http redirect target. Regarding SNI, an implemenation should avoid using an IP address for hostname if it is using HTTPS, that makes certificates more complex and creates SNI problems, but that is a general issue, not specific to CDNI. + swapping of redirecting and target host in the figures - correct, I have fixed it. Thanks for catching it. + nits - all fixed + Attacks on the fallback - we have added an explanation on how the fallback should be designed to have the same level of load balancing and redundancy as the original uCDN nodes, so that the fallback would be not expose a new attack surface (beyond the original uCDN architecture) + Scheme in fallback address - the same as in the redirect target, we have added a "scheme" property. The default is to use the same scheme as the received request. One can set a specific scheme if needed using this property.

This draft is a work item of the Content Delivery Networks Interconnection WG of the IETF. Title : CDNI Request Routing Extensions Authors : Ori Finkelman Sanjay Mishra Filename : draft-ietf-cdni-request-routing-extensions-08.txt Pages : 19 Date : 2019-11-20 Abstract: Open Caching architecture is a use case of Content Delivery Networks Interconnection (CDNI) in which the commercial Content Delivery Network (CDN) is the upstream CDN (uCDN) and the ISP caching layer serves as the downstream CDN (dCDN). The extensions specified in this document to the CDNI Metadata Interface (MI) and the Footprint and Capabilities Interface (FCI) are derived from requirements raised by Open Caching but are also applicable to CDNI use cases in general.
