Bandwidth in the send direction is managed dynamically. This means that a guaranteed minimum bandwidth is only made available for as long as a data transfer is actually in progress.
An example:
VoIP data being transmitted by a VoIP gateway should always have a guaranteed bandwidth of 256 kbps. A single VoIP connection requires 32 kbps.
As long as nobody is on the phone, all the bandwidth is available to other services. With each new VoIP connection established, the other applications have 32 kbps less, until 8 VoIP connections are active. As soon as a VoIP connection is terminated, the corresponding bandwidth is available again to all other applications.
Important: For this mechanism to operate correctly, the sum of the configured minimum bandwidths must not exceed the effective transmission bandwidth available.
