Pim van Pelt is known for SixXS, a global IPv6 tunnelbroker which ran from 2001-2017. In this journey, he found that kernel routing at scale (many interfaces, many prefixes or many packets/sec) were better handled in userspace than server kernels (either FreeBSD or Linux). Today, Pim operates IPng Networks GmbH, a small internet provider in Zurich, Switzerland. IPng Networks is using software-based off-the-shelf PC routers which will give silicon-based routers a run for their money. In this talk, we will explore Intel's DataPlane Development Kit (, open source dataplane solutions such as VPP (, DANOS (, DPDK based loadtesting ( and discuss performance benchmarking results from the field.
