Frequently Asked Questions
What is the difference between Mbps and MB/s?▾
A megabit is 1/8 of a megabyte. 8 Mbps equals 1 MB/s, so divide the Mbps figure by 8 to get the equivalent MB/s throughput.
Should I plan for peak or average bandwidth?▾
Always plan for peak demand, not average. Sustained transfers need extra headroom because real links rarely achieve their nominal maximum throughput.
