RTI Connext Gateway enables users to easily integrate various communication protocols into a DDS databus. The RTI Connext Gateway includes built in adaptors for several common protocols, including:

In addition to the included adaptors, RTI Connext Gateway includes a set of useful processors and transformations, allowing the transforming data from various formats (e.g. JSON) and use scripting (e.g. Python) to prototype data processing logic. 

RTI Connext Gateway is packaged as an open framework, based on the RTI Routing Service SDK, that allows users to easily add new adaptors, processors and transformations. 



Features and Benefits

  • Easily integrate components and devices using common protocols into a DDS system.
  • Expose devices using legacy protocols to the LAN and the WAN in a scalable, efficient, and secure manner.
  • Access devices using protocols such as Modbus without any programming. Just configure the gateway (with a simple XML file) and go!
  • Create a common, normalized information backplane that integrates devices and subsystems that use various protocols. Use RTI Connext DDS to leverage automatic discovery, publish-subscribe, QoS, content filtering, fine grained-security, IP Mobility, and other advanced features and retrofit these capabilities into systems that use less-capable and scalable protocols.
  • Leverage DDS to provide access to AI and cloud services from your edge devices.


RTI Labs Project Type: Product Prototype
