What does this do?
If you are looking to throttle SCCM’s WAN traffic an option is to throttle BITS if you do not have the traffic throttled on your network infrastructure. Server-to-Server transfers use BITS which is only aware of it’s local Ethernet connection.
Within the SCCM console you can specify to throttle traffic under the Computer Client Agent Properties found within Site Management\Site\Site Settings\Client Agents. — Be Careful — within this window you have the option to throttle “Branch Distribution Points” or all clients which is a little confusing unless you really stop and think about it. A “Branch Distribution Point” is a specific type of DP which is different than a “Standard Distribution Point”.
So, for “Branch Distribution Points” you can throttle traffic within the console (see screenshot).
Throttling BITS traffic for al clients seems a bit over the top so instead there is an option within Group Policy Preferences to throttle BITS traffic (see screenshot).
Of course you can do this with a local policy (see screenshot).
