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;

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.

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.

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.

Challenges
GSC16-PLEN-84
• 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.

Next Steps/Actions
GSC16-PLEN-84
• 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.

Proposed Resolution
GSC16-PLEN-84
• 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

RESOLUTION GSC-15/32: (Plenary) Cloud Computing (New)
The 15th Global Standards Collaboration meeting (Beijing, 30 August – 2 September 2010)
RESOLUTION GSC-16/31: (Plenary) Service Oriented Networks (Revised)
Recognizing:
a) continental electric grids, global telephone systems, and the Internet all facilitated
economic growth by expanding access to customers and resources in a way that led to
demand for new products and services;
b) Cloud Computing also has the potential to fuel a virtuous cycle of technological and
economic growth – new services spur global demand for cloud access, which in turn
leads to innovative products to enhance cloud performance;
c) the cloud’s global nature holds the promise of new entrants from all parts of the world
fueling economic opportunity on a global level; and
d) Cloud Computing will build on existing network components and functionality, e.g.
security, privacy.
The 16th Global Standards Collaboration meeting (Halifax, 31 October - 3 November 2011)
Recognizing:
a) the increasing use of service architectures for bringing software-based products to market;
b) the increasing abstraction or virtualization of network, hardware, and software resources
into services;
c) the use of service enablers or services as the fundamental unit of interoperability in
abstracted architectures including Web 2.0, IMS, and SOA;
d) the use of a service supply chain as a means of blending service enablers from multiple
applications, networks, and service providers into consumable products; and
e) service enabler creation is occurring in many PSOs as well as outside the traditional
standards process.
Considering:
a) electric grids, phone systems and the Internet have some common characteristics that
contributed to their success:
- Each promoted greater inclusion by expanding access to markets and resources
- Each established appropriate industry standards for connectivity and use
- Each gained greater value when privately developed systems were linked
- Each provided a venue that people grew to trust for facilitating commerce
- Each provided greater opportunities for competition among market participants;
b) these same characteristics will be important in ensuring that Cloud Computing realizes its
full potential as an efficient vehicle for conducting global commerce;
c) strong interoperability to facilitate communication between new and existing cloud
services and infrastructure requires well defined identity and authorization technologies
to securely span across cloud providers;
d) Cloud Computing must become a trusted foundation for new development, with
transparency on security, privacy, and management policies within the cloud, including
how data is protected;
e) Cloud Computing solutions must respect the fact that cloud users own the data that they
create and maintain in the cloud and must support the ability of users to extract such data;
and
f) that many GSC Members and other organizations have work efforts underway to address
Cloud Computing standardization.
Considering:
a) using today’s methods, significant work is required to integrate service capabilities from
different organizations;
b) integration and normalization of incompatible service enablers increases overall cost;
c) the use of common services for a common purpose improves consistency of user
experience; and
d) the reuse of service enablers where practical reduces deployment and lifecycle
maintenance costs of new products.
Resolves:
1) to identify national, regional and international initiatives and activities in the area of
Service Oriented Networks;
2) to encourage exploration of a globally compatible service catalog/registry;
3) to encourage PSOs and Observer Organizations of the GSC to build on the ATIS Service
Enabler Characterization Technical Report associated with service description and service
inventory, and to evaluate, enhance, and adopt best practices appropriate for local markets
where appropriate; and
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 Cloud Services Forum, that enhance accessibility of service standards work to the
application developer community. This may include a common developer download
package that includes information such as API definition, non-functional service enabler
characterization, and other applicable documentation.
Resolves:
1) international standards can play a significant role in facilitating the success of Cloud
Computing as a vehicle for global economic growth by establishing standards setting
