http://www.lip6.fr
) is one of the largest computer science
laboratory in France (>350 researchers) covering a wide spectrum of topics
ranging from theoretical computer science to VLSI, among them, the Network and
Performance Analysis group covers issues related to networking. LIP6 is a lab associated
with CNRS (National Scientific Research Center).
The Networks and Performance Analysis (NPA) group aims at developing a vision for the future
Internet as well as designing solutions to shape and manage it. The target of
the group is the control of ubiquitous, mobile and versatile networks that
expand everywhere in our private and professional environments. The core of our
work concerns problems related to multimedia and mobile networks, resource
management, scalability, ambient networks and peer-to-peer. Moreover, significant
work is developed in the area of Internet measurement, modelling and virtual
reality.
We are established
since the early 80s, and have developed a strong experience in networking
design and analysis. We have contributed to many emerging technologies with an
emphasis on modelling, internet protocol design and more recently mobility.
The main projects of the group have addressed various critical issues in networking, among them :
Quality of service and traffic engineering, modelling and simulation of packet networks
Our background comes from queuing systems, simulation and networking. Therefore, we have been early involved in the analysis of
emerging protocols and the design of mechanisms to improve their behaviour as well as maximize the network resource utilization. This
activity has conducted to a continuous work in traffic engineering; QoS architecture design (queue management, shaping, scheduling);
protocol development and test-beds (Wireless, IPv6); network and traffic modelling and performance evaluation of ad hoc or cellular
networks.
Network measurements and tomography
We have inititaied in France and developped an important research activity in network measurement with the leading research groups
worldwide in this area. We now contribute to the OSCAR RNRT project that associates the most active groups in network measurements.
It has also played a significant role as a meeting place for researchers coming from other backgrounds with strong interest in data
analysis (graph theory, signal processing, information theory). The association of these skills will allow us to address new emerging
challenges in various networking areas (mobility, security, modelling).
Routing : multicast, mobility, cross layer, self-organised networks, delay tolerant netwo
rks, network coding
Routing is the key issue in networking and enables the success of the internet by providing connectivity to a large set of end-users.
However, a stronger stress is expressed on this basic function as new requirements emerge. Routing can be considered as a transfer
function between the address of the destination and the location of that given host in the addressing space. Therefore, the routing
algorithm is completely dependant of the addressing structure. As a consequence, routing to mobile hosts (hosts move in space: ad
hoc, mesh or delay tolerant networks), routing to a group of host (multicast, where hosts moves in time) or addressing and routing
designs in self organized networks when no management infrastructure is available are complex tasks for today~Rs Internet. Routing in
a large-scale network where a large set of hosts is mobile as in pervasive networks. The variability of network connexions, either
due to the use of wireless links which strongly impacts routing performances (wireless mesh networks) require the study of new
solutions based on cross layer or network coding designs.
Peer-to-Peer and content Networks
Major evolution in networks and in their usage are driven by the applications. In this context, we aim at studying and developing new
architectures to support the transmission of new content. Target applications could be live video and radio, massive multiplayer
online games, sensor networks. Our main research interest are handling of live streaming, overlay optimization, end user behaviour.

ENST (Télécom Paris)
A pioneering institution in the area of Information Technologies
The school was founded more than a hundred years ago and is classed among the Grandes Ecoles d'Ingénieurs.
Because of its high scientific standards and the extremely competitive admission procedures, ENST can be
compared to the highest level engineering schools and universities that one would find abroad.
ENST is one of France's leading graduate engineering schools and is considered the leading school in the
field of Information Technologies.
Its disciplines include all the sciences and techniques that fall within the term "Information and
Communications": Computer Science, Networks, Communications, Economics and Business, Electronics, Signal and Image Processing, Social and Human Sc
iences as well as the study of economic and social aspects associated with modern technology.
Programme objectives
The two guiding principles of ENST educational policy are providing engineering training of the highest standards and developing centres
of excellence in research. ENST provides training and education in all the sciences and technology related to Information Technologies. Its students d
evelop the skills needed to design, to develop, to operate and to manage information processing and transmission systems, skills that are also necessar
y to assess networks and information systems strategically. Both training and education are stimulated by the high level research activities conducted
by the school. ENST also places great emphasis on developing the human and social qualities of the future engineers it produces, as well as their under
standing of economics and management skills. In view of their future careers, students will acquire the special skills that will enable them to work in
multi-lingual and multi-cultural environments. They must dispose of an excellent command of English and practical knowledge of a second language.
Student body and faculty
ENST today has a faculty of about 150 full-time staff
(full professors, associate and assistant professors), over 200 part-time
lecturers and a student body of about 1000 students (including 750 in the three
year diploma program, 100 in one of the Master's level programs, and 200 PhD
students. ENST's four scientific departments carry out research and teaching
activities in the school's central areas of expertise:
Department of Communications and Electronics,
Department of Computer Science and Networks,
Department of Signal and Image Processing,
Department of Economics and Social Sciences.
The Department of Modern Languages and Cultures (LC)
provides students with the skills to carry out a successful international
career. Teaching is on a term basis.
As part of their schooling, ENST students are strongly
advised to spend a period abroad. They can do this by carrying out a placement
or by enrolling in a degree programme in a foreign university. Placements
abroad can be either for short periods (2 months), between a student's first
and second year, or longer more technical placements, generally carried out at
the beginning of the student's third year. The latter are generally between
five and six months long, during which time the students carry out their first
real engineering project. Over 50% of the third year students go abroad to do
their project work. They virtually cover the globe. In descending order, the
most distant destinations are the U.S, Canada, Australia, Japan and China. Europe attracts a third of final year students, in particular Great Britain,
Scandinavia, Germany, Spain and Italy.
ENST welcomes qualified foreign engineering students in
its own laboratories and also organises for them placements with partner
companies.
Research
ENST's scientific policy is in phase with the rapid
evolution of the Information Technologies sector and the central role played by
networks and information systems today. Over the last few decades, ENST has
gained a recognised position internationally in its technical domains. In
addition to working on developments in the basic sciences, research at ENST
also aims at broadening its field of study, moving in particular towards
systems integration, innovative services on the internet and in other media,
and the analysis of users' communication practices and their social impact.
ENST thus covers all aspects of Information Technologies.
ENST is committed to maintaining an optimal balance
between scientific research, where themes remain fairly stable, and applied
research, which changes more rapidly. Research projects are organised
principally in collaboration with universities and major research groups,
notably the CNRS (Centre National pour la Recherche Scientifique). Applied
research is pursued through contractual agreements between ENST and its
corporate partners.
ENST laboratories belong to GET (Groupe des Ecoles des
Télécommunications) Research, a single research organisation that also includes
the laboratories of ENST-Bretagne and INT.

Technology
A hierarchical architecture is implemented to manage equipments, multimedia, Internet flows, customers and the growth in services and coverage.
All the best technologies and standards are combined and optimized within the architecture: DVB-S satellite technology offers the best radio quality fo
r multimedia broadcast and uses the cheapest multimedia management, modulators and terminal set top box.
The Gigabit Ethernet at the Net Head provides the best cost/performances Internet networking, compatible to all wireless IEEE standards 802.11a & 802.1
1.b/g Thus BluWan implements the best standards for cost efficiency with a high degree of scalability. Then Internet down load (the biggest flow) is pa
ssed over DVB containers (IP/DVB) to profit of the bandwidth, the DVB performances, and the low cost of equipments (set top boxes). The internet return
path and VoIP are then set on 802.xx chain, a pipe line arrangement of WiFi 5 (called hiperlan) and 2.45 (802.11a & 802.11b/g), these equipments capac
ity are compatible of enhanced return path needs.
The coverage is ensured by relays nodes; relay nodes simply retransmit the down load wide band containing multimedia and IP packets for subscribers. T
hey collect the IP return path and ensure VoIP on a dedicated VLAN Access level or "last mile" which will cover some km in dense areas up
to several tenth of km in "rurban" areas, capable of serving 400 to 1000 subscribers. Finaly, relay nodes feed several WiFi Access Point for
group of individual houses or hot spots and serve directly buildings or enterprises.
