Hello All, I need to use a portable with 2 ethernet interfaces as a bandwidth measurement device to measure the actual bandwidth used by ethernet devices. For this measurement, I inted to put the device under test and only one other pc on the hub/switch so that all other forms of ethernet/ip traffic are not present. I want to be able to route the data stream(s) into one ethernet port and out the other, with accruate measurements to verify what vendors say about the bandwidth consumption (bits/sec) of their various products.
In the past I have used bwm (BandWidth Monitor) on Debian-woody. It's a bit eradic, but somewhat useful. Googling around I found bwmon(gentoo) and bwbar(debian). Any other candidate software I should evaluate to measure BW consumed? Maybe an obscure/unknown module with ethereal would work by sniffing? I've also looked at NTOP, but nothing really jumps out to measure bandwidth consumed by a particular device/session. Last, I read an article in the March'05 issue of Linux Journal about Hierarchial Token Buckets and Queuing, that is geared towords QOS and bandwidth usage control mechanisms. Maybe this is what I need to use as a basis for developing a robust bandwidth measurement tool? http://www.linuxjournal.com/article/7562 Any suggestions or ideas are most welcome.
