This seems to be a little more complicated than rrdtool/mrtg. This sort of
accounting is extraction of flows. Known as Cisco's NetFlow Feature. Most of
Cisco routers can do netflow accounting. For the collecting of this flows you
need additional software. A well known name is Dave Plonka's Netflow. Have a
look at this links:
