background
Background
  • CSF launched mid-February 2011.
  • The committee includes the concepts of the previous SON Forum with a broader scope.
  • Initial set of deliverables identified during inaugural meeting focused on inter-provider telepresence, content distribution and VPNs.
    • Subsequently, it was agreed that the primary focus would be to complete Content Delivery Network Interconnection (CDN-I) work in a short time interval.
    • Additional information can be found at the following link

cdn i release 2
CDN-I Release 2
  • CDNI-I Release 2, targeted for completion by the end of 2011, will develop use cases and requirements for:
    • Multicast-based content delivery with applicable content types (e.g., live streaming)
    • Federated CDN-Interconnect
    • Cloud services charging (generic function driven by CDN Use Cases)
  • Other Release 2 objectives:
    • Group comprehensive requirements per applicable interconnection domain
    • Develop reference architecture for CDN-I NNI with other impacted ATIS Committees
    • Evaluate protocols including the output of the IETF CDNi Working Group (when available) to support use cases and requirements

inter carrier telepresence
Inter-Carrier Telepresence
  • Objective is to develop, by year-end, an ATIS specification describing the high-level, end-to-end message flow diagrams for access-agnostic, inter-provider telepresence
  • Both private and public cloud domains will be considered
  • End user may access these cloud domains by using wired or wireless devices
  • The focus is to use functional service enablers as defined by ATIS CSF
  • Abstracted messages between the functional elements will be used rather than specific network elements and protocol messages
  • This output is expected to be the basis of subsequent ATIS CSF service architecture specifications
cloud lifecycle checklist
Cloud Lifecycle Checklist

The checklist is being developed to facilitate the following six functions from a cloud provider:

  • Assessmentand acceptance(i.e. build) of services onto the cloud platform/infrastructure
  • Ongoing audit(i.e. capture) of services on the cloud platform/infrastructure
  • Augmentation, abridging, and annulmentof services within the cloud platform/infrastructure
virtual desktop infrastructure vdi
Virtual desktop infrastructure (VDI)
  • An initial baseline document was developed mid-year to describe the virtual desktop client requirements for CSF-defined services, to include both enterprise and consumer domains.
  • The scope of the initiative was recently revised to limit context to enterprise services (and related network architecture) only.
virtual private network vpn oriented data center services vdcs
Virtual Private Network (VPN)-Oriented Data Center Services (VDCS)
  • Initial baseline document created in support of VDCS - a generic framework to provide virtual private cloud services.
  • Objective is to develop use case specification for using the VPN network as the common control point for end–to-end services on interconnected data center resources.
in summary
In Summary
  • CSF continues on a fast track as it focuses on the next priorities.
    • CDN-I
    • Telepresence
    • Cloud Lifecycle Checklist
    • Virtual desktop infrastructure (VDI)
    • Virtual Private Network (VPN)-Oriented Data Center Services (VDCS)
  • Important synergies exist with the work on
    • Framework Development,
    • Service Enabler Definition, and
    • Vertical Service Creation.
  • The Cloud Services Forum looks forward to continued interaction with ITU-T SG13 on these important topics.
