Dual nstream is more "driver related". I had problem with dual nstreaming SR5 and 684HA cards (SR5,HA from one side, and SR5, HA from the other, I didn't have more cards to use 4 equal cards in both PCs :/). Soo I choose bonding 2 nstreams. Problem with the bonding is that one link can get up to 48-50 mbits and the other 60-65 mbits. But bonded together they can reach 95-100 mbits (soo I'm loosing around 15-20 mbits).
I'm not sure about the dual nstream.
But i prefer better way for bonding asymetric links:). (Clasicaly bonding is made for ethernet links I think).
A question on this:
- In bonding the main advantage is redundancy, but what about miss-ordered UDP packets like for VoIP applications? Have anybody here experienced that scenario? I mean a bonded link consisting of two wireless links and passing VoIP data.
