We hope to start on that tool soon, which will take these summaries of real-world network traffic and generate a synthetic load. Cramming the network full of packets is easy, but it would be really helpful if folks running Samba or Windows AD networks could run this script over a pcap file captured on your DCs so we get a good idea what 'real world' looks like. The instructions are in the perl script, they involve using tshark to parse the .pcap into XML, which this tool ingests, returning anonymous lines of traffic summaries that we can build new traffic simulations from. The resulting files are nothing like the size of the .pcap but can be a little large, but are totally anonymous and trivial to audit so we can probably keep them in the wiki or somewhere for folks who are comfortable. If you want to help, then please e-mail the output to me with some details on your network size to me in the meantime if you can.
