Linux: How to find out which process curently creates the most network traffic?

Question

From time to time connection to my server is very slow. This could be that someone is doing large uploads or downloads. Since I have a lot of software on my server I would like to find out, which process is responsible for the traffic.

Is there a simple command which lists processes which are currently doing network communication, sorted by the amout of traffic that was created in the last x seconds?

My system is running Ubuntu.

You can use something like nethogs (http://nethogs.sourceforge.net/) or iftop (http://www.thegeekstuff.com/2008/12/iftop-guide-display-network-interface-bandwidth-usage-on-linux/).
