What is difference between Upstream and Downstream WSUS Server?

Or, What is Upstream Server in WSUS?
Or, What is Downstream Server in WSUS?
Or, What are the roles of Downstream or Upstream WSUS Servers?

Upstream WSUS Server: - This is the server which is also known as primary WSUS server, and it synchronizes the patches directly from Microsoft (internet).

Downstream WSUS Server: - This is the server which is also known as Secondary WSUS server, and it downloads the patches and settings from the upstream WSUS server. We can define rules and policies on primary or upstream WSUS server to get it inherited on secondary or downstream server. No changes are allowed on the downstream server as it is controlled from Upstream WSUS server centrally.

Cheers, Please write me back if you have any query or feedback on this.
