NGN Architecture.
Vision for Networks.
Telco Service
Application
Plane
Delivery and management of content and application functionality
Control
Plane
Set-up, management and tear-down of voice and rich media connections between two or more parties
Transport
Plane
Transport of media and signalling messages and adoption of these at the edge
Aggregation Plane
Aggregation of dedicated traffic type and
Transmission to the transport plane
Access
Customer Equipment
Connection of customer equipment with the network
Interface for the customer (directly or indirectly) with the network

Slide 3

Network and IT Visions.
Similarities ?
Good enough to treat them equally!
r q p o n s n physical “terminal” device o creates location independence p abstracts transport, makes all look equal r q p o n n q controls mapping/session, virtualizes allocation r creates the service s manages functional/non-functional req.

Slide 4

Raise abstraction level.
Resource becomes service.
Makes objects self½ able services.
“Discovery” matches
Requirements and
Capabilities of Resource and Job , treats them both as services.
Introduces the Concept of Obligations on both sides.

Steering of self½ able services via SLA.
WS-Agreement as a base.
Enhancements by UBL, WSDM etc…
Whole term is an Obligation on the Customer or the Provider
Interval of Values and Definition of
Unit to describe success
Get current value and eventually perform statistical expressions
Manage the lifecycle; provision support services, manage using WebServices and get help if cannot decide at this level
Special actions and payments if this term gets violated
