Network Defense -- sampling algorithm?

[alanshieh]

Hi,

What is the sampling algorithm for the counters on Statistics Pass Through filters (as displayed in Manageability Commander => Network Policy Monitor)?

From what I can tell, it doesn't tick on per-packet basis. It seems to have something to do with link utilization level. I.e., if I send a slow stream of small packets, it ticks maybe once every 10 packets. If I send a 5 Mb stream, it ticks once every 2 packets.

Any help would be greatly appreciated!

I'm still trying to track down details here Alan, I'll post further once I can answer your question.
