Seven years that have being turned into one, by Internet
Since 1993...
TINA consortium birth!
The 1993 main focus: IN / PSTN, ATM, QoS, VoD/Videoconferencing
 Telecommunication experts forecast: the value will be more and more on
the (value added) services and content provisioning (compared to
“pipe” provisioning, or “dumb network”)
TINA, a group of technical experts defining the basis of
an architecture that clearly splits the service layer and the transport
layer with a high focus on the above mentioned acronyms and services
the first business model based on the cooperation of different service
providers
the convergence between (up-to-date) Telecommunication Technologies
and (up-to-date) Information Technologies (IT), particularly through the
use of DPEs (Distributed Processing Environment)
... for a business case, not totally identified

Seven years that have being turned into one, by Internet
... to 2000
The technical evolution...
The Internet phenomena !!!
The mobile market boom !!!!
 330 millions subscribers in Europe, in June 2000
The NGN wave, ridden also by new entrant manufacturers
... associated with the regulatory and market evolution and pressure...
copper local loop unbundling
radio local loop unbundling
UMTS standard favouring the third party service providers
... bring the missing business cases and make some TINA principles more
up-to-date than ever :
the business model,
the need of a Service Architecture
the use of the latest IT technologies and off-the-shelves environments

Concepts That are Turning into Reality
The Business Model
Deregulation, market demands make necessary to define the business
responsibilities - An overall architecture is needed
various on-going activities (ITU-T, ETSI, IETF, MSF, ISC, OMG..)
The TINA work gets acceptance in various bodies
adoption of TINA business model by ITU-T SG11
adoption of (Ret) reference point by OMG TSAS
The separation between Service Provider and Network Resource Provider
Hot topic and spread concern (NGN, 3G mobile)!!!!
Various on-going activities such as Jain or Parlay (with TINA Access Session
semantic for the Parlay framework)
The result of this work has to be endorsed by bodies driven by specific
business cases
 Parlay phase 2 adopted in UMTS for VHE

Concepts That are Turning into Reality
The Retailer
TINA SA 5.0 definition: “...providing Customers access to services”
The concept was appealing but without clear business cases few years ago...
The telecommunication landscape evolution makes the separation between
access and services a cornerstone
local loop unbundling
NGN advent with access and residential gateways
customers’ portal accessible from different devices (WAP phone, PC,...) and access
networks (ADSL, GSM, GPRS)
A good ground is naturally the Retailer Platform specifications, and the notion of
TINA Access Session

Concepts That are Turning into Reality
The Service Architecture
TINA SA 5.0 objectives:
Objective 8: “Definition of partition and layering principles leading to the separation
of services from the network and computing infrastructure and related
resources”
Objective 9: “Definition of interfaces providing an abstract view of the network
and computing infrastructure that enables service applications to make use of
network and computing resources transparently”
Objective 10: “Definition of principles and mechanisms that allow third-party
development of services and applications”

Concepts That are Turning into Reality
The Need of API
Shortening time-to-market is also facilitated by the shortening the service
development process
The service development process must be open
in term of tools and environment - towards off-the-shelves tools & environment
in term of actors - towards open and published interface
The notion of API is a enabling factor to ease and speed this step
numerous tolls and environment (C++ libraries or Java packages) available
These tools and environment are already mastered by a large community of
developers - The Internet community
API vs Protocol: they are complementary
use of protocols for specifying interaction between remote systems
use of APIs to ease the service development process
The success of APIs in telecommunication business and market relies highly on
their ability to be consistent with legacy telecommunication protocols

Some technical issues that are still to be looked at
Multi-party Call Control :
A real requirement from service provider, that implies a sophisticated flexible
accounting system, not fully implemented yet
Hopefully, in the new NGN products, less constrained (SIP, H.323)
Intelligent Peripheral Integration in a NGN network
The Intelligent Peripheral will evolve toward an Internet Integration (IP-IP)
These will create IP subnetworks with specific QoS requirements to manage by the
service providers
Services Interaction
The profile notion and its externalisation that will be more and more crucial do not
solve the problem of consistency execution of various services.
First step : For a service provider, to list the information manipulated by its services
to be able to detect the potential concurrency access of various services on the
same information.
Second step : Build a consistent execution of the various services. Yet an open
issue with some solutions to investigate.

Conclusion
Not all specifications bodies manage to turn their results into standard de facto,
widely accepted by the market. Let us remind that TINA-C primary aim was
R&D cooperation, i.e. collaborative assessment of technology innovation
Even if TINA is not a standard de facto, the Consortium has been particularly
successful in anticipating, vulgarising, influencing, promoting concepts/ideas.
Since 1993, the telecommunications context has changed dramatically : IP,
mobile, NGN.
The best TINA concepts are naturally turning into specifications and products in
the bodies addressing specific market needs (3GPP, OMG, IETF, SoftSwitch,
etc)
