November 2013: Update on CeroWrt

Posted on Nov 1, 2013 by Rich Brown.

Although the CeroWrt site (http://www.bufferbloat.net/projects/cerowrt/) has been quiet, that doesn’t mean that we haven’t been working.

The CeroWrt-Devel mailing list (https://lists.bufferbloat.net/listinfo/cerowrt-devel) has been bubbling with lots of energy all summer and fall, and we’re getting close to a new release that we can recommend to everyone. Here’s what’s we’ve been working on:

  • Significant refinement to the CoDel code, to further knock down bufferbloat
  • Update to Linux 3.10 kernel that incorporates much of our earlier work on bufferbloat
  • All the good effort from the OpenWrt Barrier Breaker development firmware
  • And too many other improvements to mention here

You can check out any number of Bufferbloat videos at http://www.bufferbloat.net/projects/cerowrt/wiki/Bloat-videos to learn more about the problem and our solutions.

If you just want good router firmware, purchase a Netgear WNDR3800 and burn the current 3.7.5-2 firmware. You can also follow our activity on the CeroWrt-devel list to see what’s happening and learn when experimental builds or solid new releases are available.
