Calculating Bandwidth

Community Manager

Last week, we discussed ways to tune your network performance to improve end-user experience and speed up connectivity.


Network and migration planning is a crucial step prior to migrating to Office 365 to allow you to verify and test the estimated bandwidth. But even after deploying, it’s important to continue to monitor the amount of bandwidth available on the network and estimate if the existing capacity could handle high volume days.


See below for calculators and resources to help you monitor your network bandwidth:



At Ignite last year, Ed Fisher and @William Looney walked through different methods for calculating bandwidth, including Excel calculators, the overestimation approach and measurement based extrapolation. Watch their presentation below!
