Research question
 How to reduce telecommunications service
construction time while affecting non-negatively
other parameters (e.g. Cost, QoS, QoE) ?

RQ 1 Construction process

RQ 2 Software tools RQ 3 Tool building process


Agenda

 Challenges in telecom service life-cycle
 How to reduce telecom service construction time ?
 Solution/Contribution:
1.Telecom service construction process
2.Tool building process
3.Software tools for telecom service construction
 Conclusion and perspectives


Solution: Telecom

1.Model
2.Test
3.Collaborate
4.Interoperate


Solution: Telecom

Solution:
Tool building

Solution: Modeling
with DSMLs

Domain Specific Modeling
Language (DSML) = graphical 1.Model
language that offers
2.
●
expressive power focused 3.
on a particular domain, 4.
●
to visualize, specify,
construct and document the
artifacts of a software-
intensive system.

2000]


Solution:
Modeling

Solution: Testing
through leverage of COTS

Components Off The Shelf
(COTS) = ''a commercially 1.
available or open source 2.Test
piece of software that other
software projects can reuse
3.
and integrate into their own 4.
products''

[Torchiano, 2004]


Solution: Leveraging the COTS – Transform
to MM testing

the justification behind
decisions, the reasoning
that goes into
determining the design of
the artifact.

Solution/Contribution: advantages
 Provides a method
Method = - a set of modeling conventions (Modeling Language - ML)
- a process: - provides guidance as to the order of the activities,
- specifies what artifacts should be developed using the ML.
[Ramsin, 2008]

 Reflects current practices in industry
(more easily) accepted by practitioners
 Relies
on models and offers high automation
degree
more rapid software tool building
 Contributes
towards fulfilling all Service Providers'
and Developers' requirements

Solution/Contribution: perspectives
●
Introduce more flexibility
(e.g., iterative, agile) in the
construction process.
●
(Semi-)automatic integrating
of testing/simulation results
into models.

●
Construct Telecom
DSML MMs from e.g.
Frameworx ●
Implement the
●
Define alignment interoperability
measures to ensure process
viewpoint
interoperability (e.g.
