I've searched for ages on the internet, but haven't found anything.
I'm looking for a free network monitor, which, when installed on my PC, would show the network usage statistics by application. So it'd say that Skype download at 10kbps and uploads at 5kbps, Firefox downloads at 120kbps and uploads at 20kbps, etc. It needs to work in real time and can be either graphical (usage graphs) or can just display the usage as text. It must be freeware.
Thanks for your help in advance.
