You must create exactly one instance of this class before carrying out any other RNS operations, such as creating destinations or sending traffic. Every independently executed program must create their own instance of the Reticulum class, but Reticulum will automatically handle inter-program communication on the same system, and expose all connected programs to external interfaces as well. As soon as an instance of this class is created, Reticulum will start opening and configuring any hardware devices specified in the supplied configuration. Currently the first running instance must be kept running while other local instances are connected, as the first created instance will act as a master instance that directly communicates with external hardware such as modems, TNCs and radios. If a master instance is asked to exit, it will not exit until all client processes have terminated (unless killed forcibly). If you are running Reticulum on a system with several different programs that use RNS starting and terminating at different times, it will be advantageous to run a master RNS instance as a daemon for other programs to use on demand.

In custom RNS network implementations, it is possible to change this value, but doing so will completely break compatibility with all other RNS networks.

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, but it can be configured individually on a per-interface basis.
