1. Before You Get Started¶
1.1. What is Connext Drive?¶
RTI Connext® Drive is RTI’s automotive grade communication framework, enabling the automotive ecosystem to comply with the portability, evolvability, flexibility, and integrability requirements of the industry. Built on the proven Data Distribution Service™ (DDS) standard, Connext Drive provides an abstraction layer that eases development by hiding hardware and OS-specific details. It provides tools and software services to help build automotive software components for all stages of the development cycle, from research to production.
Connext Drive provides the safety and security needed to build for the future while being the only framework supporting AUTOSAR and ROS2. In this bundle, you will experience how Connext Drive enables automakers to quickly and easily meet the most complicated demands of the automotive market to power next-generation vehicles, such as:
Bridging legacy platforms and new technologies to create a Next-Generation E/E Architecture;
Integrating complex data sources for sensor fusion and high performance computing applications in autonomous systems;
Orchestrating safety functionality over ethernet;
Connecting to off-vehicle systems for real-time, including remote operations and telemetry.
Connext Drive includes these components:
SDKs that provide you with APIs to help you send and receive data using communication patterns based on the Data Distribution Service™ (DDS) standard.
Tools that help you visualize your data and debug your distributed system.
Infrastructure Services that can perform dedicated functions in your system, such as routing, recording, and replaying data.
1.2. Bundle Overview¶
To support both non-safety and safety-critical use cases, the Connext Drive bundle contains the following:
Connext Professional: RTI’s full-featured, industrial-grade libraries designed to meet the demanding connectivity requirements of autonomous systems. Connext Professional enables rapid development, deployment, and upgrades of widely-distributed teleoperation applications.
Connext Micro: RTI’s libraries optimized for environments with size, weight, and power constraints.
See Safety-certified libraries below to learn how Connext Micro supports programs with safety requirements.
1.2.1. Safety-certified libraries¶
For programs with safety requirements, RTI offers libraries that have been safety-certified to ISO 26262 ASIL D – the most stringent automotive functional safety level. These libraries and safety evidence are available for purchase as an add-on product, Connext Cert, RTI’s safety-certified framework.
Connext Cert is built from the same code base as Connext Micro, but only uses
a subset of the features and APIs available in Connext Micro. Look for the
tag in the Connext Micro API Reference
to view the features available in Connext Cert. Engineers can begin
experimentation and development work with the standard Connext Micro product, which
is included in the Connext Drive host bundle under
In the “license-managed” Connext Drive bundles (ones with
lm in their name, such as
rti_connext_drive-2.0.0-lm-x64Win64VS2017.exe), Connext Micro has been built with
only the features available in Connext Cert and included as a binary library and header
files to give an accurate representation of the functionality and performance available
within Connext Cert.
