Interoperable Internet-Enabled DDS Applications

DDS (Data Distribution Service) and RTPS (Real-Time Publish Subscribe) are good candidate technologies for the Industrial Internet of Things (IIoT). However, the discovery protocols in RTPS assume that the underlying network supports multicast and that datagrams are not subject to network address translation (NAT). Both of these assumptions are violated in a typical IIoT application. This article presents a solution to these problems by introducing a service that relays RTPS messages.

Online Training

If you’re getting started with OpenDDS, here’s a great way to begin your journey. OCI is offering the following live online training in OpenDDS. Each class consists of two 3-hour sessions.

New Article: Using OpenDDS in the Cloud

Today, the ability to build applications that communicate effectively in the cloud and public Internet is critical, but we face certain challenges running OpenDDS in environments that don’t provide multicast. In this article, we present a simple solution for running interoperable OpenDDS applications in a cloud environment.

Building OpenDDS with DDS Security for the Raspberry Pi

We updated the Raspberry Pi Quick Start to use a modern version of GCC and to include steps for building OpenDDS’s DDS Security optional features.
