Bandwidth qos of Oracle dataguard

We are going to build DR system by using dataguard.

The bandwidth between Primary DC and DR DC is 100Mbps, it is enough for redo-log apply in normal sync mode, but when we initial the DR database, there are tones of redo logs and it will used up the bandwidth without network qos control.

I know the best practice is to set qos on network level between primary DB and standby DB, but I am curious whether we can set qos parameter on oracle level for dataguard redo log apply?

Thanks,

James
