It probably would. I thought of it, but I'm not all that familiar with the storage requirements to gather netflow data. My initial impression was that it was rather large. I know at work we have a dedicated machine with a LOT of fast disk on it to gather and accumulate the netflow data from the various building and border routers. There is also the issue of how do you define a flow when all you ever see is stateless datagrams. At this point the router is not looking inside the packets it forwards. I'll have to look into it. - Brian

Would Netflow not sort this out? There are open source packages for collecting Netflow data, that way you have a better understanding of the traffic passing to each gateway and protocols they pass 73, Ruben - ON3RVH
