2011

Submitted the libtrace paper on Monday.

Finished my little study of the protocol mixes in the latest ISP data. Definitely looks like P2P usage has dropped compared with earlier this year. Some of the graphs can be found at http://www.wand.net.nz/~salcock/skynet/

Released a new version of libprotoident and libflowmanager.

Got back to working on libwandbgp. Finally managed to get it working without segfaulting, but still having problems with keeping the route table "up to date".

Graph scales in the traffic analysis

Shane,
I notice that the graphs in your analysis are misleading at first glance due to different scales for the "before" and "after" graphs. For example:
http://www.wand.net.nz/~salcock/skynet/graphs/unknown_udp_bytes_in_jan11...
... has a scale 0 to 0.3.
http://www.wand.net.nz/~salcock/skynet/graphs/unknown_udp_bytes_in_sep11...
... has a scale 0 to 6.
A 20 to 1 difference. At first glance, the graphs show a decrease, but if you scale them equally they show an increase.
Just wondering....

Re: Graph Scales

Hi Don,

Thanks for your comment.

Yes, you're absolutely right about the misleading scales - the result of quickly hacking up some scripts to automate the graphing process :)

Will definitely look into fixing the scales when I do the next set of measurements (probably this coming January).
