No. As mentioned, the SUP plays no part in this really. The client downloads 
the catalog/metadata from WSUS in response to many different things including 
new deployments, the software update scan cycle, and even all by itself if you 
haven’t disabled automatic updates.

Jason,

Don’t the clients only download the meta-data for the catalog from the SUP in 
response to a policy issued by the SUP after a successful sync not the catalog 
itself?

My understanding is that clients process the catalog’s meta-data and then 
retrieve only the software updates that apply.

The SUP really has no knowledge of the update catalog at all. The client 
retrieve the update catalog directly from WSUS. They cache the catalog and 
generally only download deltas when needed. I don’t know all of the cases where 
a full download is required but a WSUS change is certainly one and Microsoft 
mucking with the catalog too much is another one (as they’ve done this multiple 
times in the past in turn causing lots of network traffic and pain).

Hi,

we were wondering something at my current position and i can't find the answer 
anywhere.

Configuration Manager clients will get software updates metadata many times 
(scan scheduled, deployment, after a deployment...).

The question would be:

Once the SUP Server has finished synchronizing with Windows Update, it will 
modify its catalog version and ask the clients for a scan (therefore a catalog 
download).
Is this catalog download only a delta or a full download?

And in which case the catalog would be fully downloaded on clients ? (except 
when their assigned SUP is not the same as last catalog download)

Thanks.

Jérémy.
