When running a SpeedFusion vpn tunnel to combine bandwidth from multiple WAN connections on a Balance 210, what happens if one connection starts to suffer an issue?
1.) What happens when 1 of 2 connections starts to suffer latency suddenly of 250ms? Is there a way to tell the balance to discontinue use of that wan until health returns to normal? Would a latency increase on one of the links cause timing issues that drastically impacts the connection? What might the experience be like in this temporary condition?
2.) What happens when 1 of 2 connections has an upload speed issue, but latency remains normal. To give some numbers, let’s say normal bandwidth is 1.0 mbps upload per line. Having two lines, under normal circumstance results in SpeedFusion having upload speed of 2x1.0 - 19% overhead = 1.62 mbps.
What happens if one connection drops to 0.4 mbps?
Would SpeedFusion/Balance 210 handle this in stride and deliver 1.0+0.4 - 19% overhead = 1.13 mbps. Or would the suddenly slower second connection bog things down more? (assuming no packets are lost and latency remains stable)
