Huge Sized download taking place at port 8530 between clients and WSUS\SUP of secondary site

Hi Guy's

Need a solution to the issue, the SCCM 2012 clients under a secondary site { Secondary site with SUP\WSUS } are downloading 200Mb + data at port 8530. This seems quite abnormal.

Need to know answer of below

1- Actual size of catalog what clients should download or path where on WSUS is stored

2- How to restrict a huge sized download between WSUS and CM 2012 client

This is not the case where clients are directly reporting to Primary size.
