Hello,
I will start soon to renegotiate our MPLS contract (approx 20 sites all around the world).
I got the actual statistics of the bandwidth usage (with the usual drawback of that monitoring tool: precise date only for the last few days, sample rate from 1 minute...). Do you have engineering rules to determine the required bandwidth using the statistics?
I used to take the average bandwidth in business hour and to order a link 5 times bigger (for example: 10Mbps average bandwidth => 50Mbps MPLS link). Anyway, that's only by experience. I would be curious if they are some engineering rules to calculate that.
