The IP Networking Lab (INL) of the Departement of Computing Science and Engineering at Université catholique de Louvain(UCL) in Louvain-la-Neuve, Belgium gathers about ten researchers, both PhD students and postdocs.

Today, IP networks are mainly used for data communications and Internet access. Within the next five years, it can be expected that IP networks will also be used to carry other more stringent applications such as telephony, IP TV, ... The INL is actively working on scalable tools, techniques and protocols to allow IP network operators to better support such demanding applications in an Internet that will grow by several orders of magnitude.

The INL has strong commitment to both applied and academic research. We collaborate with other research groups in Belgium and abroad, network manufacturers and network operators. We also contribute to standards within the IETF and IRTF.

Internet transport protocols usually evolve slowly.
Any significant evolution to TCP, the dominant transport protocol,
takes years of efforts to be widely deployed. There are several
factors that explain this slow evolution. QUIC,
initially proposed by Google, addresses those issues
and brings back innovation in the transport layer.
The results obtained by Google with QUIC combined
with its security features have convinced the IETF to standardise a new protocol starting from Google’s initial design.

How to measure the impact of the research conducted in a university lab ? There are many metrics that could be used, funding bodies have a tendency to look at quantitative metrics such as number of publications, number of citations, ... Within the IP Networking Lab, our main objective is to perform good and useful work. Some of this work has been recognised with prestigious awards :
