I work it out another way...
Determine redo creation a hour, and then ask Networks to provide the
required bandwidth to transfer that volume in a hour.
You can use the redo log generation over 24 hours to draw a graph, showing
how it goes up and down and give them the required rate per hour.

Hello list,
we are in process of deploying a Data guard and i am looking to get a
bandwidth requirements. While googleing i came across the below formula
multiple times..my question is what exactly do the below numbers represents
0.7, 8, 1000000 ?? i know we can get and redo rate bytes per sec from
v$sysmetric_history but confused on the numbers...
*Required bandwidth = ((Redo rate bytes per sec. / 0.7) * 8) / 1,000,000
= bandwidth in Mbps *
