traffic between DP and client

Question

hi
i have DP of sccm version 1902.
in my place we have network switches with 1GB every port.
when i deploy TS to class with 30 computers , other computers that belong to same switches of this class having slow network.
the problem is because 30 computers download operation system in same time.
after this phase in TS, there is no problem.

there is an idea to solve this problem ? maybe to reduce the network traffic from DP to client ?

thank you

Hi
Thank you for all
branchcache not for me because i deploy OS with WinPE.
i use multicast but it dosn't work in first try ( maybe because the DP and clients are not in same Vlan).

Thank you

Thank you for posting in Microsoft Q&A forum.
You may use branchcache, branchcache is a peer-to-peer technology, it allows Windows machines on the same subnet to download content from each other, this allows a content to be downloaded from the DP only once and the clients will just get the content from other clients that already have the content. However, branchcache only works with Windows in the full OS. It does not work in WinPE.
And multicast only works in WinPE, and all clients would have to be downloading the same content at roughly the same time. This mechanism has the advantage of requiring the least load on your network because the content it placed on the network only once.

Hi,
Sounds like Multicast could maybe help, should reduce the overall data transferred over the uplink.
Peer cache could also help so the clients share data between the clients instead of pulling it from the DP.

I would try something like that out before restricting traffic.
