Slogan: 
A tool for evaluating the deployment of Add-Paths in an ISP network

This work is supported by Cisco URP grand and Trilogy project

The Add-Paths Analyser is a tool that evaluates the cost of enabling Add-Paths on the routers of an ISP. Based on a model of the network, it runs simulations to compare the behavior of the network using classical BGP versus the behavior of the same network using Add-Paths. Different Add-Paths selection modes can be explored and compared with each other.

SyClick Symposium on Click Modular Router

Multi-core CPUs, along with recent advances in memory and buses,
render commodity hardware a strong candidate for software router
virtualization. We would like to share the experience of a 3-year
research project on the design and implementation of a platform
for high-performance and flexible virtual routers on multi-core
general purpose PCs.

The Click software suite is a core component of our platform and has
been extensively used to prototype the data plane of our virtual
router platform. In particular, we exploited Click to analyse the bottlenecks of our

Nivelles adhère au projet FON: danger ou opportunité ?

Mon, 01/04/2010 - 19:53 by Damien Leroy • Categories:

La ville de Nivelles a annoncé il y a quelques mois son intention d'adhérer au projet FON [1,2], un projet de partage de WiFi communautaire. Ce qui peut s'apparenter à une très bonne idée au premier abord, pose pas mal de questions à la fois techniques et juridiques. N'étant pas juriste, je ne ferai que mentionner les côtés juridiques, sans entrer dans leurs détails.


Google launches public DNS resolvers

Fri, 12/04/2009 - 01:48 by Olivier Bonaventure • Categories:

During the 1990s, most DNS resolvers were open, i.e. any host could send a query and obtain an answer from a DNS resolver and most of them handled recursive queries as well. Then, during the 2000s, open DNS resolvers suffered from more and more security problems and best current practices suggest that DNS resolvers that are installed inside company networks should only be accessed by the users of company and that requests from remote users would be blocked.
