How does HyperIP handle congestion between two sites? For example, what will happen if the link/network between two sites is not dedicated or there is no bandwidth guaranteed?
HyperIP will modify its send rate, backing down to the receive rate of the remote HyperIP. Congestion will cause the receive rate to go down, since congestion will cause packets to either get dropped or be delayed. The sending side will try to recover from the congestion slowdown by cautiously, but continuously, attempting to increase the send rate. This Dynamic Rate Adjustment has the effect of maximizing overall WAN throughput by accelerating data on the HyperIP segment of the circuit.
