What does it do? 

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 and above, 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
