I found NTOP-XTRA (for windows) which does the job partially. BUT i'm still looking for a tool which can monitor host traffic per process (.exe).
Ntop-xtra is provided with no charge, built on top of open-source project ntop. It has plenty of options to see traffics statistics, relatively easy to configure and can dump data selectively to the disk (rrd). It can be also configured with your router, if it supports NetFlow collector (e.g., instructions for dd-wrt firmware) and monitor traffic of your entire home LAN in details. Unfortunately, it does not provide any info about processes that initiate network activity.
