accumulated in the cache) sends NetFlow data from the cache to a NetFlow collector
for data analysis.
A packet of flow records or version 9 templates (or both) that is periodically sent to
the NetFlow collector based upon an export criteria.
A Dragon Security Command Console (DSCC) or third-party software application(s)
