Hey all, I wanted to see if my math makes sense for converting total traffic 
amounts to bit rate using sampled netflow.

Converting bytes (total) to bits per second (throughput) using sampled netflow 
rough estimate:

netflow sample rate: 1:500
bytes (after sampling): 3639786
bytes (before sampling): 500 * 3639786 = 1,819,893,000
bits total : 1,819,893,000 * 8 = 14559144000
bps : 14559144000 / 300 = 48530480
48,530,480 (48Mbps)

formula = bytes * sample rate (500) * 8 [conversion to bits] / time of netflow 
sample (300)

This is just a general estimation, not an exact figure, i get that but is there 
any way to make it more accurate (anyone see a glaring problem with it?)

thanks,
-Drew
