Home Bandwidth Comsumption - Part 2
By brfoley on Jun 13, 2005
I finally started my "bandwidth monitoring" test from home. While I'm accumulating the statistics I thought people might be interested on how I'm gathering the stats.
Look back at my earlier blog about "Home networking gone wild" and you'll see a diagram of my home network. The goal of this test is to measure my inbound & outbound internet traffic and not the traffic that's local to the home network. The biggest "challenge" is that virtually all of todays "hubs" are really "switches". And the issue with switches is that you cannot view the traffic on all the ports from a single port.
So the solution is to track down an old ethernet hub. That is a real hub that does shared traffic across all the port. Fortunately a compatriot in my office had one stashed away and was willing to lend it to me for a little while.
With that accomplished I could now "instrument" my internet connection as follows.
With the Solaris 10 laptop plugged into the ethernet hub I can than run the open source tool called "ethereal" to snarf all the traffic between the internet and my home router.
I'm only a few days into gathering statistics when will report back what I find out.
