Long Flows Reported by NetFlow
I-Heng Mei, Les Cottrell, and Connie Logg
Updated: Wed Jan 29 10:35:41 PST 2003
Long Flows: Sometimes NetFlow reports a greatly inflated elapsed time for some streams during a test run. This causes the passive throughput calculations for that day to be inaccurate, and adversely affects the correlation between passive/web throughput and active/passive throughput. Currently, we define a long flow to be any flow that lasts longer than 100 seconds (this threshold may be lowered). A normal stream during one of the bandwidth tests should last at most ~20 seconds. Note, long flows have also occurred in web100 data, but only three times (all on transfers between SLAC and node1.rcf.bnl.gov).
The tables show the ratio of the # of long flows to the # of total flows for each node/test.
