  1. ATISIIFUse Cases and Relevance to CDNI Presented to IETFCDNIBoF March 2011 Bruce Thompson, Cisco

  2. ATIS-0800042 IPTV Content on Demand Service • Published on 11 January, 2011 • Built on ATISIIF, ITU-T, 3GPP & IETF Specifications • ATIS Internet Source Content • Builds on Architecture Defined ATIS-0800042 • CoD Services between Content, Network, and Service Providers • Two Use Cases Relevant to CDNI • Off Net Delivery, Internet Sourced Content • ATISIIF Relation to CDNI • ATISIIF architecture group focuses on developing architectures • Prefers to reference existing protocols where ever possible • ATISIIF will be evaluating protocols defined by CDNI for inclusion in Internet Sourced Content Architecture

  3. ATISCoD to CDNI Functional Mapping • ATIS Location Control =CDNI Request Routing • Interface to DownstreamCDN Through ATIS Location Control • ATISC2 = CDNIRequest + Acquisition • ATISC2 = HTTP + Extensions for Media Resources, Scheduled Delivery • Media Resource Metadata Describes Media Resource Structure • Profiles Defined for Different Media Resource Classes • MPEG-TS, ABR, etc. • Includes Bandwidth, etc. of Media Resources

  4. Off Net Delivery • Content Hosted by ATIS Service Provider Delivered to Roaming Subscribers • Roles • ATIS Service Provider Operates Upstream CDN • Network Service Provider Operates Downstream CDN • CDNI Interfaces / Protocols Between Upstream / Downstream CDN • Matches Current CDNIProblem Statement & Requirements

  5. Internet Sourced ContentTransparent Operation • Internet Sourced Content • Content Hosted by ATIS Content Provider • Content Delivered to ATIS Service Provider Subscribers Through SP CDN • Service Provider Owns Access Network • CDN Path = ATIS Content Provider >> Network SP>> ATIS SP >> Subscriber • CDNI Transparent Operation • ATIS SP Appears as CDNI User Agent; Plays No Role in CDN Selection • Matches Current CDNIProblem Statement & Requirements • Approach May not be Optimal for Service Provider • Service Provider Provides Quality Guarantees to Subscribers • Path from Content Provider to Service Provider May be Bandwidth Constrained

  6. Internet Sourced ContentCDNSelection Influenced by ATIS Service Provider • Internet Source Content Use Case – Same as Slide 5 • CDNSelection Influenced by ATISService Provider • ATIS SP Appears as CDNI User Agent; Influences CDN Selection Path • Implementation Approach • ATIS SP Signals Attributes Required for Path Selection Via CDNI Request Protocol • Example: ATISC2 Scheduled Transmission Service Request Header • Upstream CDN Includes Required Attributes in Request Routing Requests • Matches Current CDNI Problem Statement – Adds New Requirements • Additional Attributes for CDNI Request Routing Protocol
