How can I measure bandwidth for a network? I'm familiar with ethereal and a couple other network sniffers but after sampling the traffice I have no idea if it's high, low, is there a limit, etc.. I sample the results and save them so that I can compare with problems in the future but I seriously look at the results and it's like DUH! I have no idea what is high or low.
Is there any rule or way to measure and know what is the exact saturation point of a LAN? We have 70 users and nine servers on an ethernet LAN. 5 100 swithes for the users and 2 GB switches for the server room. A GB trunk links all switches.
I've noticed that our network might hit 150 to 200 packets per second. Again I can't say how large they are so I have no idea if this is horrible or not.
Thanks in advance!
