NetOS is a project led by Prof. Luigi Rizzo
Dipartimento di Ingegneria
Università di Pisa
and aimed at the development of production-quality implementations of
recent research results in the area of Networking and Operating Systems.
The project builds on over 15 years of activity in developing
open source software and contributing
to open source projects (FreeBSD
Software developed by NetOS covers most operating systems including
FreeBSD, Mac OS X, Linux, OpenWRT and Windows,
and is normally available under a BSD License.
Support for NetOS comes from own funds and contributions from
- netmap, a framework for fast access to network
devices, capable of generating/receiving 14.8Mpps
with a single core at 1.33 GHz.
- geom_sched, an infrastructure for
disk scheduling in FreeBSD. Initial release March 2009, integrated
in FreeBSD in April 2010.
- The dummynet emulator, linux and Windows
versions, released Feb.2010
- The qfq scheduling algorithm, part of dummynet.
Integrated in FreeBSD in Feb.2010.
