I have two Peplink MAX HD2s and both have firmware version 6.2.0 loaded. I have two WAN connections over 802.11 radio links at 2.4 GHz and 5 GHz, each supports high bit rates and low latency (4-8 ms). I also have the AT&T cellular connection, which has a moderate bit rate but high latency (~150 ms). All three are bonded together using SpeedFusion.
Most of our traffic is streaming video which uses UDP. When the cellular is part of the bonded connection the high latency of the cellular causes significant degradation of the video. I have seen other discussions here on the forums saying to not mix the high latency and low latency links for streaming video. That all makes sense.
What I want to do is set up an outbound policy to force all of this UDP traffic to go over the two high quality WAN links. I tried each of the various outgoing policy algorithms with various settings. I use the weighted algorithm with the cellular set to 0 or 1. I tried the priority and lowest latency algorithms. In every case the traffic still seems to be partially going over the cellular connection causing the video to be degraded.
I could reduce the priority of the cellular connection so that it is only used in the event the two WAN links fail, but I worry about the time to remake the connection with cellular. that seems to cause a temporary outage.
Do you have any advice, how should I address this?
