RTPS well-known port mapping configuration.
RTI Data Distribution Service uses the RTPS wire protocol.
The discovery protocols defined by RTPS rely on well-known ports to initiate discovery.
These well-known ports define the multicast and unicast ports on which a Participant will listen for discovery
metatraffic from other Participants.
The discovery metatraffic contains all the information required to establish the presence of remote DDS entities in the network.
The well-known ports are defined by RTPS in terms of port mapping expressions with several tunable parameters,
which allow the user to customize what network ports are used by the middleware.
In order for all Participants in a system to correctly
discover each other, it is important that they all use the
same port mapping expressions.
