The Real-Time Publish Subscribe (RTPS) protocol is the interoperability protocol used to allow multi-vendor Data Distribution Service (DDS)[1] implementations to communicate

The Real-Time Publish-Subscribe (RTPS) protocol is designed for use with Internet Protocol (IP) one-to-many Multicast and connectionless best-effort transports such as IP User Datagram Protocol (UDP).[2]

The main features of the RTPS protocol include:[3]

  • Performance and Quality-of-Service (QoS) properties enabling best-effort and reliable publish-subscribe communications for real-time applications using standard IP networks.
  • Fault tolerance allowing the creation of networks without single points of failure.
  • Extensibility allowing backward compatibility and interoperability through extensions of the protocol and enhancement with new services.
  • Plug-and-play connectivity for new applications and services allowing automatic, configuration-less discovery by applications joining and leaving the network at any time.
  • Configurability allowing balancing the requirements of reliability and timeliness for each data delivery transaction.
  • Modularity allowing simple devices to implement a subset of the protocol and still participate in the publish-subscribe network.
  • Scalability enabling systems to scale to very large publish-subscribe networks.
  • Type-safety preventing application programming errors compromising the operation of remote nodes in the publish-subscribe network.
