OMG DDS For Extremely Resource-Constrained Environments (DDS-XRCE)

The task of designing integrated solutions is frequently met with challenges when unusual architectural constraints from system and non-system sources are introduced into the equation. In this SETT article, Object Computing Solutions Architect, Marc Neeley, explores how today’s industry standards are addressing complex integration challenges and provides a detailed review of the OMG specification, DDS for eXtremely Resource Constrained Environments (DDS-XRCE), which plays a significant role in extending solutions into environments with unique requirements.

Online OpenDDS Training

Here’s a great way to get started using OpenDDS. OCI is offering the following live, online OpenDDS training classes, each consisting of two 3-hour sessions.

• December 3-4, 2019: Introduction to OpenDDS Programming with C++
• December 5-6, 2019: Introduction to OpenDDS Programming with Java

DDS Foundation Meet & Greet

The DDS Foundation and Object Management Group (OMG) invite you to a free evening reception for DDS practitioners and researchers who wish to gain the latest information and insights on DDS, the proven data connectivity standard for mission-critical, industrial-grade applications.

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.
