Abstract
Object Management Group (OMG) Data Distribution Service (DDS) DomainParticipants communication methods and system are provided using the Real-Time Publish Subscribe (RTPS) wire protocol over one or more wide area networks (WAN). Three main issues are addressed: Network Address Translation traversal, Changes in IP addresses, and Efficient bandwidth utilization. Embodiments lead to a scalable solution for WAN Connectivity of DDS Applications using RTPS Wire Protocol. This is a connectionless solution that works on top of UDP as the IP transport. The key benefits of this solution are: Low latency communication with reliable and best-effort data delivery, Minimal data loss when moving across networks, including firewalls/NATs, Minimal migration impact for existing applications. No changes to the API, and Scalability using UDP versus legacy TCP solution. A new UDP WAN transport avoids connection-based overhead inherent in TCP, which becomes increasingly problematic as the number of communication endpoints increases.
