Getting Started
If you are new to RTI Connext, start here. The RTI Connext Getting Started Guide will teach you core concepts and guide you through writing your first application examples.

Platforms and Building Applications
The Platform Notes includes platform-specific instructions on compiling, linking, and running Connext applications. It also describes which features are supported for each platform.
Other documentation includes this addendum to the Getting Started Guide:
User's Manual
To learn about a Connext concept in depth, consult the Core Libraries User's Manual. This comprehensive guide is the definitive reference for the SDK.
The Extensible Types Guide is an important addition to the Data Types chapter in the Core Libraries User's Manual.
The Limited Bandwidth Endpoint Discovery (LBED) plugin is an alternative to Simple Endpoint Discovery, designed for environments with low or limited bandwidth, intermittent connections, or other network challenges. LBED is included with Connext.
API Reference
Once you begin active development, you will want to consult the extensive API documentation. Connext supports C, C++, Java, C#, and Python.

RTI Code Generator
Code Generator creates the code needed to define and register a user data type with Connext.
RTI Connext XML-Based Application Creation
XML-Based Application Creation simplifies the development and programming of Connext applications. It allows you to specify in XML format all the aspects of a DDS system.
RTI Distributed Logger
Distributed Logger is a library that enables applications to publish their log messages to Connext. The log message data can be visualized with RTI Monitor and RTI Admin Console. Or you can write your own visualization tool.

QoS and Property Quick Reference Guides
Connext provides comprehensive support for configurability and Quality of Service (QoS). Applications can take advantage of this to prioritize the different data topics and message-flows, control the amount of history maintained by the middleware caches, ensure reliable delivery of information, accommodate low-bandwidth or high-latency links, etc. This cheat-sheet provides a convenient summary of all the QoS policies:
The Property QoS Policy stores name/value (string) pairs that can be used to configure certain Connext parameters that are not exposed through formal QoS policies. This cheat-sheet summarizes all the Connext properties:
Builtin QoS Profiles
Several QOS Profiles are built into the Connext core libraries and can be used as starting points when configuring QoS for your Connext applications. The default builtin profiles are here:
XSD Schema
Connext provides XSD files that describe the XML format of types, QoS profiles, and XML-based Application Creation configuration files.

- RTI Connext DDS QoS Profiles XSD Schema
- RTI Connext DDS XML-based Application Creation XSD Schema
RTI Ada Language Support
For more information on Ada Language Support, see these documents:
Infrastructure Services
RTI Routing Service
Routing Service is an out-of-the-box solution for integrating and scaling DDS-based applications across domains, LANs, and WANs, including firewall and NAT traversal.
If you want to build your own custom adapters so that you can bridge custom protocols and input/output streams to Connext, see these documents:
RTI Recording Service
Recording Service can reliably record large amounts of real-time data without having prior knowledge of the data types or topics in the system. You can also replay the recorded data to replicate the original data flow.
- Release Notes
- User's Manual (PDF version)
- Recording Service Tutorials, Replay Service Tutorials, and Converter Tutorials
- RTI Record XSD Schema
- RTI Replay XSD Schema
If you want to build your own plugins to read and write to custom storage, see these documents:
RTI Persistence Service
Persistence Service saves data from Connext publishing applications in memory or permanent storage.

RTI Cloud Discovery Service
Cloud Discovery Service is a standalone application that enables deployment of Connext applications in dynamic environments where UDP/IP multicast is not available. It must be downloaded and installed separately.
If you want to programmatically control Cloud Discovery Service execution, see the following API documentation:
RTI Queuing Service (Experimental)
Queuing Service brokers interactions between message producers and consumers, delivering each message to only one consumer.
RTI Web Integration Service
Web Integration Service uses a simple, standards-based interface to provide a transparent bridge between web-based services and unmodified DDS applications. It must be downloaded and installed separately.
Tools
RTI Launcher
Launcher provides a convenient graphical interface for installing, configuring, and running Connext components.
RTI Administration Console
Admin Console provides a graphical interface to visualize data as well as debug and administer Connext applications.
RTI DDS Spy and DDS Ping
DDS Spy is a convenient command-line tool for peeking at the data in your DDS system and debugging when your applications are not communicating. It returns data in a text format rather than the graphical format of Admin Console.
DDS Ping is another command-line tool that uses Connext to send and receive preconfigured ?Ping? messages to other rtiddsping applications. It can be used to test network/computer configuration and environment settings that affect the operation of Connext.
RTI Monitor
Monitor provides a graphical interface showing QoS settings as well as numerous metrics including resource and protocol statistics.
RTI Shapes Demo
Shapes Demo is a graphical application that powerfully demonstrates the capabilities of Connext without requiring any programming.
RTI System Designer
System Designer allows you to graphically design and configure Connext systems. Think of it as a user interface (UI) to XML-Based Application Creation.
RTI Connector (version 1.3.0)
Connector provides a set of simplified APIs that enables you to quickly develop demos, proofs of concept, and test applications using a variety of scripting languages.
Transports
RTI Real-Time WAN Transport
Real-Time WAN Transport is a Connext transport plugin that enables communication over wide area networks (WANs) using UDP as the underlying IP transport-layer protocol. It must be downloaded and installed separately.
- Release Notes (PDF version)
- Installation Guide (PDF version)
- User's Manual (or see the RTI Real-Time WAN Transport part of the PDF version)
RTI TCP Transport
TCP Transport enables participant discovery and data exchange using the TCP protocol (either on a local LAN, or over the public WAN). It is included with Connext Professional.
- User's Manual (or see the RTI TCP Transport part of the PDF version)
- API Reference
RTI TLS Support
TLS Support is an optional product for use with TCP Transport. It must be downloaded and installed separately.
Observability Framework
RTI Connext Observability Framework is a holistic solution that provides deep visibility into the current and past states of your Connext applications using telemetry data. This visibility makes it easier to proactively identify and resolve potential issues. Observability Framework must be downloaded and installed separately.
Limited Bandwidth Plugins
The RTI Limited Bandwidth Plugins are designed for environments with low or limited bandwidth, intermittent connections, or other network-related issues. The plugins must be downloaded and installed separately.
RTI Security Plugins
The Security Plugins include a robust set of security capabilities, including authentication, encryption, access control, and logging. This Connext add-on product includes the Builtin Security Plugins, which are the main security plugins, and Lightweight Builtin Security Plugins, for resource-constrained systems. Additionally, Security Plugins supports loading customers' own security add-ons in the form of customized plugins built using the Security Plugins SDK.
RTI Log Parser (Experimental)
RTI Log Parser is a command-line tool that processes and enhances Connext log messages, making it easier to debug applications. For information on using this experimental feature, see this document:
