Aims and objectives throughout the project
Questions of availability and rapid configuration remain at the core of the
network; in contrast, quality of service problems are moving more and more
from the core of the network toward access points and stub site. With the
arrival of IPv6, networks are going to spread out and cover new application
domains, such as home automation. The PRATIC project deals with several
aspects related to this architectural evolution. In the core of the network, we
define the optimal meshings permitting the best reliability with regard to
resource use. However, our research focuses more on access networks and
terminal networks. In access networks, we study the mechanisms of ensuring
quality service during congestion or degradation of bandwidth, as in the case
of UMTS networks (radio linking modeling, auctioning techniques, metrology,
packet marking as a function of flow semantics, performance of transport
protocols). In terminal networks, we look at the auto-configuration of
networks, as well as the level of the addressing plan, and quality of service
routing.
