Is there any third party software that can manage the bandwidth allocation better than router QOS?

Coz QOS only can set the priority, and go by ports.

I have an ipad2 on the network everytime it streams videos it will take up all bandwidth that i can't even surf lyt. I don't mind streaming but i'd like to be able to limit the bandwidth say to 80% of the 1.5Mbps...

Ipad such a bandwidth hogger.
