CeroWrt is a routing OS built on the OpenWrt firmware . It is a research project intended to resolve the bufferbloat epidemic in home networking today, and to push forward the state of the art of edge networks and routers. SubProjects include proper IPv6 support, tighter integration with DNSSEC, and most importantly, reducing bufferbloat in both the wired and wireless components of the stack.
The final CeroWrt 3.3 “Sugarland” build is
3.3.8-26 , built
on 18 Sept 2012.
