You may want to try netflow based tools.
Cisco has some, and there are some free ones out there
(e.g. CAIDA's cflowd) that are worth a try.
There are also some tools to summarize flow data.
And you may want to look at Dave Plonka's flowscan...
(Just filing some "flowdumps" will enable yoou to answer
questions like "which was the top talker yesterday between
1pm and 2pm, or how many bytes where sent originating at port 1214).
