Object Management Group Issues DDS-TSN Request for Proposals
Allows DDS infrastructures be deployed on, and leverage, TSN-enabled networks

Needham, MA – October 8, 2018 – The Object Management Group® (OMG®), an international, open membership, not-for-profit technology standards consortium, issued a DDS-TSN RFP seeking submissions to define rules for mapping Data-Distribution Service™ features onto TSN concepts in order to support the design, deployment and execution of DDS systems over TSN networks in a standardized fashion. By putting DDS on top of TSN, engineers can leverage the infrastructure of DDS with the advanced networking properties of TSN to create a powerful distributed data-centric integration framework with high reliability and availability properties.

According to the report, "Time Sensitive Networking Market By Component, By Application, By Component, Competition Forecast & Opportunities, 2013-2023,” published by TechSciResearch, the global time sensitive networking market is projected to grow at a CAGR of over 53% from 2018-2023, due in part to increasing demand for industrial IoT (IoT) and industrial automation applications.  

Both members and non-members of OMG can participate in the process by submitting a Letter of Intent by March 20, 2019. In order to become a submitter, individually or as part of a submission team, companies must become members of OMG by the initial submission deadline of November 11, 2019.

DDS™ is a family of standards from OMG used in large-scale, mission-critical systems that depend on secure, real-time data exchange in complex distributed networks, such as aerospace and autonomous vehicles. It is fundamentally designed to work over unreliable transports, such as UDP or a wireless network, without requiring central servers for peer-to-peer communications or multicasting. Time Sensitive Networking (TSN) is a collection of standards developed by the TSN task group of the IEEE 802.1 working group that enables deterministic, highly-reliable communication on standard Ethernet. With its support for different types of QoS, a single TSN network infrastructure can be used to communicate mission-critical data with real-time delivery requirements side-by-side with non-critical data.

“With the advent of TSN plus DDS, Industrial Internet networks will be able to converge towards a single, commodity solution for real-time exchange of all data,” said Reinier Torenbeek, Systems Architect at RTI, an OMG member company and lead author of the RFP. “The TSN approach to traffic classes and one-to-many streams has significant similarities to DDS. A solution with DDS on top of TSN will facilitate the use of the proven and successful DDS infrastructure while maintaining the advanced networking properties provided by TSN including determinism, latency guarantees and robustness. An OMG DDS-TSN standard will allow the creation of interoperable solutions and tooling, truly unlocking the power of TSN for Industrial Internet applications."
