Cases on load balance
I. Similar rates between WAN interfaces or no disparity for example: VDSL2 100/100 & LTE
100/50Mbps
Select SDB:
VDSL: 90% of speed on upstream/downstream
LTE: 90% of speed on upstream/downstream
II: Huge speed disparity between WAN interfaces for example WAN ETH 1000/1000 & LTE
100/50Mbps
Select WRR. And the speed ratio between the interfaces is 10:1, so put WRR at 200:20.
Ethernet WAN: 90% of speed on upstream/downstream
LTE: 90% of speed on upstream/downstream
