Ease the configuration process and manage the complexity of building large systems with RTI System Designer

RTI System Designer is a fully productized feature, from Connext 6.1, forward. For customers on Connext 6.1, the functionality is built in to the product. For customers not yet migrated to Connext 6.1, RTI System Designer is available from this web page for a limited period of time. 


RTI System Designer is a graphical tool that allows you to define and configure Connext® systems. You can use it as a user interface to XML-Based Application Creation, a mechanism that allows users to specify all the aspects of a Connext system in XML format including:

  • Data Types that will be used to communicate information in the system
  • Topics that will be used in the domain, each associated with a Data Type
  • Domain Participants that can potentially be used in the system
  • Data Writers and Data Readers present within each Domain Participant, each associated with its corresponding Topic
  • Quality of Service libraries and profiles and their use to configure all the DDS Entities in the system

RTI's XML-Based Application Creation infrastructure takes care of the rest creating the Domain Participant, registering the Types and Topics and populating all the configured Entities. (Want to learn more about XML-Based Application Creation? Start here.)  View the System Designer demo.

Writing this XML by hand can be quite challenging. While a good editor with auto-completion capabilities and an understanding of the XML schema provided can be of great help, it is still quite complicated... especially as the project gets bigger and involves multiple files.

RTI System Designer can help ease this process and manage the complexity of large systems.
