  1. Welcome to the ATIS CSFTutorial • March 30, 2011; 11 AM ET • 866-742-2029, passcode 202-662-8663 • We appreciate your cooperation in making this a successful call, please: • Introduce yourself and state your company’s name and committee affiliation before contributing to a discussion • Do Notplace the phone bridge on hold • Turn Off other communication devices or Move Them Away from the phone you are using • Mute Your Phone if you are not speaking, to avoid unnecessary echoing (*6 to mute, #6 to unmute if your phone is not equipped) • Dial “00” for Operator Assistance

  2. Cloud Services Forum Tutorial Andrew White Cloud Services Forum ChairGary MunsonCloud Services Forum Vice Chair March 30, 2011

  3. Tutorial Objectives • What is Cloud? • How is this relevant to communications? • What is the Cloud Services Forum? • How did this group come into being? • What are the goals and objectives? • How can the CSF interact with other ATIS groups to leverage the current work and knowledge base for Cloud Standards? • How can we ensure compatibility in the Cloud across the related committee standards?

  4. The Creation of CSF • The CSF is the newest ATIS Forum. • The CSF was formulated in part to address how service providers will leverage core network and service attributes to adopt, advance and deliver Cloud computing services. CSF is emphasizing an integrated network/IT perspective in its approach. • This CSF work draws heavily on business use cases that demonstrate Cloud services' potential.

  5. The Early Cloud Standard User Interface Common Platform Global Communications + = • Uniform addressing plan • Single, automated user interface • Attach anywhere, call anybody • On demand, scalable

  6. Broadening Perspective on Cloud (illustrative) Traditional view Expanding the view. Examples: Web-based applications Internet apps (e.g., Facebook, Android Marketplace) Network APIs & Device ( e.g., Parlay X / ParlayREST, Presence, MMS, Content Delivery) Inter-Provider networking services (e.g., Control Plane, VPNs)

  7. Service Enabler Packaging User End Users End users interact with the business application oblivious of the component parts. Subscriber Service Applications Service Interaction Management is used to blend service enablers into a business application. Service Interaction Reuse Service Enablers Service Resource Applications Storage and Computing Networks App App App The Service Enablers expose resources (applications, data, and connectivity) through a defined, reusable interface. Data Data Data Access & Transport

  8. Service Enabler Characterization Partial Illustration

  9. Service Creation in the Cloud Service Enabler Characterization provides key non-functional data to populate Service Catalog Service Catalog Core Competency Service Interaction Management Partner Enablers Service catalog and service interaction managers speed time to market and improve service enabler reuse

  10. Fast Forward to Today • Intuitive • Indispensible • Service-oriented • Integrated into your life Same Concept, More Apps

  11. Quiz The most important aspect of cloud is: • A fast, always available network • The most intuitive user experiences • The best services infrastructure • Skilled people to put it all together • All of the above

  12. Inter-Provider Content Distribution Network • Network Providers cooperate to cache/distribute content into each other’s networks to download content more locally to users. • Reduced consumption of network resources • Reduced download latency • Consider the arrangement for doing this as cloud service infrastructure. • General interest/resonance/willingness to have this item be the initial priority focus in CSF.

  13. Inter-connected CDN Delivery Model Between Carriers (Cache based distribution) Carrier-2 Network & CDN Carrier-1 Network & CDN Content Delivery Node. Content Delivery Node. Routing, Back-office, etc. Routing, Back-office, etc. Content Delivery Node. Network Peering Storage, Origin, etc. Storage, Origin, etc. Content Delivery Node. Content Delivery Node. Content Delivery Node. Note: only data path is shown for clarity. Request & back-office path not shown. User Content Data Path Node Cache Fill Data Path User is getting content sourced from Carrier 1; delivery node is Carrier 2’s, i.e., local.

  14. Inter-connected CDN Delivery Model Between Carriers (Multicast based distribution) Carrier-1 Network Carrier-2 Network Back-office Back-office AMT Relay Network Peering AMT GW Content Delivery Node. Content Delivery Node. Multicast Source Multicast content Note: only data path is shown for clarity. Request & back-office path not shown Tunneled multicast content Users are getting content sourced from Carrier 1; Replication occurs only in Carrier 2’s network.

  15. Peer-Peer Inter-connected CDN Model Interface Domains Bi-Lateral Agreement Between Two Carrier CDNs. Assume that each carrier peers with another carrier at the CDN Level Operations & Customer Care Operations & Customer Care SLA/outages/ticketing, Special customer requests Back-Office Back-Office Provisioning, Logs, settlement Routing Routing Traffic distribution, load management, AMT Relay addresses Delivery Delivery Features, Capacity reservation, Origin access, multicast sources/groups Network Interconnection Network Interconnection Access, Security Carrier-2 Carrier-1

  16. CDN Federation Model Interface Domains Federation Exchange: Assume that there is a trusted 3rd party for facilitating federation SLA/outages/ticketing, Special customer requests Operations & Customer Care Operations & Customer Care Provisioning, Logs, settlement Back-Office Back-Office 3rd Party Routing Routing Traffic distribution, load management, AMT Relay addresses Features, Capacity reservation, multicast sources/groups Delivery Delivery Origin access Network Interconnection Network Interconnection Access, Security Carrier-1 Carrier-2

  17. Inter-Provider Content Distribution Network(Near Term Issue Focus) • Goal is to achieve implementable specifications quickly. • Initial milestones: • CSF Issue #011 Cloud Service Framework for CDN (AT&T, ZTE) • March 31 – Description of Cached & Multicast Models • CSF Issue #013 Cloud Services Network-Network Interconnect (AT&T, Cisco, Fujitsu) • April 30 – Service Level Functional Requirements for Peer-Peer NNI

  18. CSF Issues • Cloud Service Framework for CDN (AT&T, ZTE) • Cloud-Based Inter-Provider Telepresence: Access Agnostic End to End Service Flow (Service Architecture Document): In considering Telepresence and VPNs Service Definitions (Cisco, ZTE) • Cloud Services Network-Network Interconnect (AT&T, Cisco, Fujitsu) • Charging for Cloud Services (AT&T) • Cloud Service Logging and Auditing (ZTE) • Cloud Services Control Plane (Cisco, Huawei, ZTE) • Guidelines for COTS/Third-Party Software Installation in a Cloud Environment (Qwest, Harris)

  19. Cloud Activities in other SDOs • Cloud Security Alliance • IETF CDNI Birds of a Feather • ITU-T SG 13 • NIST • TM Forum • Others…

  20. Synergies with other ATIS Committees • IIF • Security and Identity Management in the Cloud • Reusability of SEs • Content Distribution Concept • PRQC • Quality of Service in the Cloud • PTSC • Cloud Interconnection in the NGN • Identity Management

  21. Q&A • How can Cloud Services Forum work with you?
