IWL gave me time and space in their offices to try out their test tools against cerowrt. Bufferbloat, TCP, IPv6 - Testing CEROWRT with Maxwell Pro
Even though I wore my lucky hat, we found 45 problems - admittedly most of which were differences in the interpretation of one RFC or another - but a few needed to be fixed (had a crc issue in one test for example) - AND the crash bug was bothersome. (looks like a fragmentation or encapsulation bug. It was hard to reproduce, but
I went away and worked on fixing a few of these, and bugs elsewhere, (mostly unaligned instruction traps) and hope to return to their labs to see if the darn crash bug is gone, after I get back from england next month.
I was simply delighted by their toolset. In addition to the generally anal protocol test suite, they have cute tools with sliders and so on
to simulate delay and packet loss in a fast, natural intuitive manner
through their boxes.
IWL was also very good in pointing out to a recent robotics competition that bufferbloat in the case of robots getting through house fires, etc, could be a real problem....
It is very hard to make a living selling test tools, yet everybody
should have them. +1 to iwl for helping make the internet better,
and grokking #bufferbloat
. See their stuff at:http://iwl.com/
(And they have a GREAT green screen.)
