For receiving bandwidth control, packets can be buffered and only belatedly confirmed. Thus TCP/IP connections regulate themselves automatically on a smaller bandwidth.
Each WAN interface is assigned a maximum reception bandwidth. This bandwidth will be accordingly degraded by every QoS rule that guarantees a minimum bandwidth of reception on this interface.
- If the QoS rule has been defined connection-related, the reserved bandwidth will be unblocked immediately after releasing the connection and the maximum available bandwidth will increase accordingly on the WAN interface.
- If the QoS rule has been defined globally, then the reserved bandwidth will be unblocked only after the ending of the last connection.
