The maximum percentage of interface bandwidth that, at any given time,

may be used to propagate announces. If an announce was scheduled for

broadcasting on an interface, but doing so would exceed the allowed

bandwidth allocation, the announce will be queued for transmission

when there is bandwidth available.

Reticulum will always prioritise propagating announces with fewer

hops, ensuring that distant, large networks with many peers on fast

links don't overwhelm the capacity of smaller networks on slower

mediums. If an announce remains queued for an extended amount of time,

it will eventually be dropped.

This value will be applied by default to all created interfaces,
