WARNING: If you are a manager with travel budget cutting approval please read no further: delete this mail NOW! nanog-scan aggregates people packets by their autonomous system names. At Nanog-21 it was used to look at top people flows by company ;-) suggestions for future functionality include categorization of flows into service types such as Vendor, ISP, IXP, EDU, ORG, as well as time-series trending and visualization of past nanogs. as expected from flow data, there is rapid decay of the distribution and a long tail.
