Abstract
Merging of new international
competitors in a global deregulation context leads to new optimization
problems in telecommunications. This presentation addresses Least Cost
Networking, a strategic issue in a competitive environment. Mainly Voice
services are considered in their international context and related modeling
and optimization issues are examined. Two complementary topics are presented.
The first focuses on basic
network design and routing strategies for new inter-national operators.
Traffic is flowed on a meshed overlay network build on own leased lines
but can be overflowed to competing operators. All layers: Transmission,
Voice trunk and Call, and best balance between overlay and external routing
are simultaneously optimized, taking into account several services (off
net and on net traffic, prepaid cards, etc.). A model is presented and
heuristically solved using a combination of Tabu Search and Erlang fixed
point. Some results from real life problems are presented and analyzed.
The second topic addresses
the impact of deregulation on international networking and least cost routing.
The first part deals with impact on accounting rates of new refile and
alternernate calling procedures. Issues from both public administrations
and new competitors are examined. Finally, opportunities for members of
an international alliance in sharing some common ressources are examined.
Biographical Sketch
Alain Sutter obtained
a PhD in Operation Research at CNAM University, Paris. For three years
(87-90), he pursued an academic research activity, published in international
journals, mainly in combinatorial optimization, and taught O.R. at an Engineering
School of CNAM University.
In 1990, he joined CNET,
the Research Division of France Telecom, as a researcher and, in the last
three years, as the head of the "Optimization of Transmission and Transport
Networks" Group, in charge of important strategic studies for deployment
of SDH rings in the France Telecom network.
In 1996, he left CNET to
found, with Dr. Boissin, a spin off company from CNET, called Boissin &
Sutter Optimisation (BSO), which develops optimization software for Telecom
operators.
