I am introducing a new device in my network. It will sit behind my router before my LAN Switch. I assume it will affect /change the traffic coming in and out of my LAN.
Now, before I introduce this appliance I would like to measure the bandwidth usage, latency/speed as well as 'size' of traffice coming in and out of my network; and do the same after the introduction of this device.
That way I can measure the changes after this new device is installed.
My LN network is mainly Windows based and my traffic includes, ftp, vpn, http, https
what kind of tool, application, or method would you suggest that I should use to achieve this goal.
