About inter-process communication

Network Manager processes communicate using TCP connections, multicast, and Really Small Message Broker.

About Really Small Message Broker
Communication between the Network Manager core components is managed by Really Small Message Broker. To ensure the correct operation of Network Manager, Really Small Message Broker must be running at all times.
About multicast
Processes that use direct TCP communication first use multicast to locate each other, then set up TCP sockets.
