Below sentence is from a Cisco technical document.
Note: The traffic in it means network traffic.
For the highlighted phrase, can I say "all of the customer sites"?It is much easier to predict the traffic and thus the bandwidth requirement of one site than to predict the complete traffic model between all the customer sites.
I have a little confusion about using "all of ... " and "all ...", not sure which situation should use "all of ..." and which should be "all ...".
Please help, thanks.
There's no difference here- both are fine.
