2. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Highlight of Current Activities ATIS Cloud Services Forum (CSF) inaugural meeting held February 2011 CSF is focused on standardizing the inter-operator interconnection required for horizontal integration of high priority commercial applications. Initial objectives that are being discussed include: –Content delivery network interconnection; –Inter-carrier telepresence; –Virtual desktop infrastructure; –Cloud-based VPN control; and –Cloud lifecycle checklist. 2

3. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Highlight of Current Activities Content Distribution Networks (CDN) Interconnection Use Case Specification and High Level Requirements (ATIS-0200003) (a.k.a., CDN-I Release 1) published June 2011: –Addresses software content items, a cache delivery model and peer-to-peer CDN to CDN. –The Use Cases and supporting requirements cover the life cycle of interactions between a Primary CDN Provider and a Supporting CDN Provider whose network serves as the access vehicle for End Users requesting the content. –The objective is to derive a set of interaction requirements to gain an initial understanding of necessary routing request capabilities and provide a framework for an eventual multi-provider CDN federation concept. –CSF offered a CDN-I webinar in July 2011. 3

6. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Highlight of Current Activities CDN-I Release 2 targeted for completion in 2011, develops use cases and requirements for: –Multicast-based content delivery with applicable content types (e.g., live streaming); –Federated CDN-Interconnect; and –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; and –Evaluate protocols including the output of the IETF CDNi Working Group (when available) to support use cases and requirements. 6

7. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Highlight of Current Activities Fast track work occurring on inter-carrier telepresence: –Multiple carriers; multiple suppliers. Work plan includes: –Initial draft specification; –Prototype activity; and –Published standard incorporating lessons learned from the prototype. 7

9. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Highlight of Current Activities ATIS CSF is developing a Cloud Lifecycle Checklist/Standard that facilitates management of the following six functions with a cloud provider: Assessment and acceptance (i.e., build) of services onto the cloud platform/infrastructure; Ongoing audit (i.e. capture) of services on the cloud platform/infrastructure; and Augmentation, abridging, and annulment of services within the cloud platform/infrastructure. 9

10. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Challenges Increasing the tempo of standards development to meet the commercial needs of operators; Horizontal integration and compatibility of work across SDOs enabling best of breed implementations; and Encouraging developers to use multi-vendor, standards-based software over single supplier verticals. 10

11. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Next Steps/Actions There are two fundamental models that the CSF needs to address: –Integrated service supply chain (e.g., CDN-I); and –Inter-carrier communications (e.g., telepresence). Telepresence and CDN-I provide commercial priority to accelerate timelines and provide focus while delivering reusable infrastructure enablers. Virtual desktop infrastructure priority drives framework for structuring service enabler interaction. Cloud VPN controls increase network value and add to the framework inventory. 11

12. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-PLEN-84 Proposed Resolution ATIS supports the revision of GSC-15/31: Service Oriented Networks as follows: – Resolves #4: –to encourage PSOs and Observer Organizations of the GSC to evaluate and adopt common standards, administrative practices, and data models, similar to what has been done in ATIS SON Cloud Services Forum, that enhance accessibility of service standards work to the application developer community… ATIS supports the reaffirmation of GSC-15/32: Cloud Computing 12
