Content Distribution Networks (CDN)
Interconnection
Use Case Specification and High Level Requirements

(ATIS

(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.

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


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


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
i
nfrastructure priority drives
framework for structuring service enabler
interaction.


Cloud VPN controls increase network value and
add to the framework inventory.

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…

The 15
th

Global Standards Collaboration meeting

(
Beijing, 30 August


2 September 2010
)

Recognizing:

a)

c
ontinental
electric grids
,
global
telephone systems, and the Internet
all
facilita
ted
economic growth by
expanding access to customers and
resources in

a way that
led to
demand for new products and services
;

b)

Cloud C
omputing
also has the potential to
fue
l

a virtuous cycle of
technological and
economic growth


new services

spur global demand for cloud access
, which

in turn
leads to
innovative produc
ts to
enhance cloud performance;

c)

t
he
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 C
omputing will build on existing network components and functionality, e.g.
securit
y, privacy
.


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 privatel
y developed systems were linked

-

Each provided a venue that people grew to
trust for facilitating commerce

-

Each provi
ded greater opportunities for competition among market part
icipan
ts
;

b)

t
hese same characteristics will

be important in ensuring that Cloud C
omputing r
ealiz
e
s

its
full potential
as an efficient vehicle
for conducting
global
commerce
;

c)

s
trong interoperability
to facilitate communication between new and existing cloud
service
s and infrastructure
requires well defined identity and authorization technologies
to securel
y span across cloud providers;

d)

C
loud
C
omputing
must become
a
trusted foundation for new development,
with

transparency on securi
ty, privacy, and management policie
s within

the
cloud
, in
cluding
how data is protected;

e)

C
loud
C
omputing
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)

t
hat many GSC Memb
ers and other organizations have wo
rk efforts underway to address
C
loud
C
omputing standardization
.


Resolves:

1)

i
nternational standards can play a significant role
in facilitating the success of Cloud
C
omputing as a vehicle for global economic growth by esta
blishing standards setting

The 1
6
th

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 enabler
s

or service
s

as

the fundamental unit of interoperability in
abstracted

arch
itectures
including Web 2.0, IMS, and SOA;

d)

the use of
a

service supply chain as a means of blending service enablers from multiple
application
s
, network
s
, and service providers into consumable products
; and

e)

service enabler creation is occurring in many PSO
s as well as outside the traditional
standards process
.


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 increas
es 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
explor
ation

of
a
global
ly

compatible

service catalog
/registry
;

3)

t
o encourage PSOs and Observer Organizations of the GSC
to build on the ATIS
Servi
ce
Enabler Characterization Technical Report

associated with service description and service
inventory, and to evaluate, enhance, and adopt best practices appropr
iate for local markets
where ap
propriate; 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 develope
r

community.

This ma
y include a common developer download
package that includes information such as API definition, non
-
functional service enabler
characterization, and other applicable documentation.
