The DRC Bandwidth Trends tab shows Dynamic Rate Control statistics over time.

Dynamic Rate Control allows the Hub to regulate the tunnel traffic by lowering each remote appliance’s Tunnel Max Bandwidth. The smallest possible value is that appliance’s Tunnel Min(imum) Bandwidth.

Dynamic Rate Control

Tunnel Max Bandwidth is the maximum rate at which an appliance can transmit.

Auto BW negotiates the link between a pair of appliances. In this example, the appliances negotiate each link down to the lower value (100 Mbps).

However, if A and B transmit at the same time, Hub could easily be overrun.

If Hub experiences congestion:

  • Enable Dynamic Rate Control allows the Hub to regulate the tunnel traffic by lowering each remote appliance’s Tunnel Max Bandwidth. The smallest possible value is that appliance’s Tunnel Min(imum) Bandwidth.

  • Inbound BW Limit caps how much the appliance can receive.
