Presentation Transcript

  1. CDNI Metadata Interfacedraft-ietf-cdni-metadata-00 CDNI Working Group IETF 85 Atlanta, GA November 7, 2012 Matt Caulfield (mcaulfie@cisco.com)

  2. Working Group Draft Submitted formerly draft-cjlmw-cdni-metadata-01 Matt Caulfield, Kent Leung, Francois Le Faucheur, Ben Niven-Jenkins, Grant Watson, Rob Murray resolved conflicts with draft-ma-cdni-metadata-03 Kevin Ma

  3. Base Set of Metadata What is the default set of metadata that all CDNs must support to interoperate? Current metadata:Acquisition sourcesLocation, Time Window, and Protocol ACLsAuthentication

  4. XML vs JSON How should metadata be encoded? draft-ietf-cdni-metadata-00 includes both encodings Pick one to use consistently across all CDNI interfaces

  5. Relationship with Capabilities Should CDN capabilities be tied to metadata? i.e. CDN capabilities are summarized by a list of metadata properties that the CDN supports e.g. CDN A advertises to CDN B that is supports metadata properties x-feature-1 and x-feature-2. If CDN B receives a request for delivery with x-feature-1 then it can redirect to CDN A

  6. Metadata Rewriting Should metadata be rewritten between CDNs? CDNI Metadata may include URIs pointing to a uCDN If passed through multiple CDNs, how should these URIs be rewritten?

  7. Next Steps Solicit comments on draft-ietf-cdni-metadata-00 Close on open discussion items Verify alignment with other drafts
