download randomizations options

[Migration User]

Hi,

In the communications setting (SEPM), we have two parameters:
hearbeat and download randomizations options.
 if I set heartbeat to 60 min, will that mean all clients will download the av signatures  and ulpoad log in the same time each one hour?
what does randmizations mean?
 
regards.

in simple terms heartbeat is

What is the difference between Push and Pull modes when downloading policies and content from the management server?
Clients that use the Push mode download policies and content as soon as they become available. On push mode an open connection is kept so that the manager can contact the client immediately when data is available. Clients that use the Pull mode download policies and content based on the Heartbeat interval setting, which is set to 5 minutes by default. Because of the greater network bandwidth that is used with the push mode, it is recommended more for small and medium-sized networks.

From Help file randomization  means

Randomization Options

Enables you to minimize the effect of multiple clients trying to download updates at the same time. You can configure the clients to download updates at random times. You can specify a range of time before or after the update is scheduled to start for the download to occur. The range of time can be days or hours, which depends on the frequency you selected.

Meaning not making all the clients to update at once which increase network traffic
sometimes liveupdate transfers are huge, to minimize this you can set this  option

Download Randomization 

Specifies a randomization option. You can stagger the updates, plus or minus the value that is specified, to minimize the impact on network traffic. By default, Symantec Endpoint Protection randomizes the LiveUpdate sessions to minimize bandwidth spikes.

thank you rafeeq
thanks Prachand
now things are well clarified

The heartbeat is when the client checks in (PULL MODE) with SEPM and sees if theres any policy changes or newer def updates it needs to download.

Best to my knwoedge, this interval time is based upon the time the client was first installed - e.g. every 60 minutes = will be once an hour from the time it first registered in SEPM.

Randomization as they say above, to stop sEP killing some branch oiffices (like SAV did), but GUP's (Group Update Providers) could also be looked at to protect bandwidth.

Good Luck with your deployment.
