Your network might experience traffic congestion when multiple client computers attempt to download content from a LiveUpdate server. You can configure the update schedule to include a randomization window on Windows or Linux clients. Each client computer attempts to download content at a random time that occurs within that window.
The schedule settings in the LiveUpdate Settings policy do not control randomization for the client computers that download content from the default management server or from a Group Update provider. You can change the randomization settings for those computers in the Communication Settings dialog box for the group to which they belong.
To randomize content downloads from a LiveUpdate server
Under Policies, click LiveUpdate.
On the LiveUpdate Settings tab, right-click the policy that you want to edit, and then click Edit.
Under Windows Settings, Mac Settings, or Linux Settings, click Schedule.
Under Download Randomization Options, check Randomize the start time to be + or - (in hours).
This setting is in days, if you select Weekly updates.
Optionally, change the duration for the randomized start time.
