Implementing Software Virtual Routers on Multi-core PCs using Click

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

Incentives for BGP Guided IP-Level Topology Discovery

Internet topology discovery has been an attractive research field during the past decade. In particular, the research community was interested in modeling the network as well as providing efficient tools, mostly based on traceroute, for collecting data. In this paper, we follow this track of rendering traceroute-based exploration more efficient. We discuss incentives for coupling passive monitoring and active measurements. In particular, we show that high-level information, such as BGP updates, might be used to trigger targeted traceroutes.
