<dd><p>This class is used to initialise access to Reticulum within a
program. 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.</p>
<p>As soon as an instance of this class is created, Reticulum will start
opening and configuring any hardware devices specified in the supplied
configuration.</p>
<p>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).</p>
<p>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.</p>

<dd><p>The MTU that Reticulum adheres to, and will expect other peers to
adhere to. By default, the MTU is 507 bytes. In custom RNS network
implementations, it is possible to change this value, but doing so will
completely break compatibility with all other RNS networks. An identical
MTU is a prerequisite for peers to communicate in the same network.</p>
<p>Unless you really know what you are doing, the MTU should be left at
the default value.</p>

<dd><p>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.</p>
<p>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.</p>
<p>This value will be applied by default to all created interfaces,
but it can be configured individually on a per-interface basis.</p>
