Product Overview

What Is RTI Connext DDS Micro?

RTI Connext DDS Micro is network middleware for distributed real-time applications. It provides the communications service programmers need to distribute time-critical data between embedded and/or enterprise devices or nodes. RTI Connext DDS Micro uses the publish-subscribe communications model to make data distribution efficient and robust. RTI Connext DDS Micro simplifies application development, deployment and maintenance and provides fast, predictable distribution of time-critical data over a variety of transport networks. With RTI Connext DDS Micro, you can:

  • Perform complex one-to-many and many-to-many network communications.
  • Customize application operation to meet various real-time, reliability, and quality-of-service goals.
  • Provide application-transparent fault tolerance and application robustness.
  • Use a variety of transports.

RTI Connext DDS Micro implements the Data-Centric Publish-Subscribe (DCPS) API within the OMG’s Data Distribution Service (DDS) for Real-Time Systems. DDS is the first standard developed for the needs of real-time systems. DCPS provides an efficient way to transfer data in a distributed system.

With RTI Connext DDS Micro, systems designers and programmers start with a fault-tolerant and flexible communications infrastructure that will work over a wide variety of computer hardware, operating systems, languages, and networking transport protocols. RTI Connext DDS Micro is highly configurable so programmers can adapt it to meet the application’s specific communication requirements.

RTI Connext DDS Cert versus RTI Connext DDS Micro

RTI Connext DDS Micro and RTI Connext DDS Cert originates from the same source base, but as of RTI Connext DDS Micro 2.4.6 the two are maintained as two independent releases. The latest release with certification evidence is RTI Connext DDS Cert 2.4.5. However, features that exist in RTI Connext DDS Micro and RTI Connext DDS Cert behave identically and the source code is written following identical guidelines. RTI Connext DDS Cert only supports a subset of the features found in RTI Connext DDS Micro. In the API reference manuals, APIs that are supported by RTI Connext DDS Cert are clearly marked.

Optional Certification Package

An optional Certification Package is available for systems that require certification to DO-178C or other safety standards. This package includes the artifacts required by a certification authority. The Certification Package is licensed separately from Connext DDS Cert.

To use an existing Certification Package, an application must be linked against the same libraries included in the Certification Package. Contact RTI Support, suppo[email protected][email protected][email protected]ti.co[email protected]m, for details.

Publish-Subscribe Middleware

RTI Connext DDS Micro is based on a publish-subscribe communications model. Publish-subscribe (PS) middleware provides a simple and intuitive way to distribute data. It decouples the software that creates and sends data—the data publishers—from the software that receives and uses the data—the data subscribers. Publishers simply declare their intent to send and then publish the data. Subscribers declare their intent to receive, then the data is automatically delivered by the middleware. Despite the simplicity of the model, PS middleware can handle complex patterns of information flow. The use of PS middleware results in simpler, more modular distributed applications. Perhaps most importantly, PS middleware can automatically handle all network chores, including connections, failures, and network changes, eliminating the need for user applications to program of all those special cases. What experienced network middleware developers know is that handling special cases accounts for over 80% of the effort and code.

RTI Connext DDS Micro supports mechanisms that go beyond the basic publish-subscribe model. The key benefit is that applications that use RTI Connext DDS Micro for their communications are entirely decoupled. Very little of their design time has to be spent on how to handle their mutual interactions. In particular, the applications never need information about the other participating applications, including their existence or locations. RTI Connext DDS Micro automatically handles all aspects of message delivery, without requiring any intervention from the user applications, including:

  • determining who should receive the messages
  • where recipients are located,
  • what happens if messages cannot be delivered.

This is made possible by how RTI Connext DDS Micro allows the user to specify Quality of Service (QoS) parameters as a way to configure automatic-discovery mechanisms and specify the behavior used when sending and receiving messages. The mechanisms are configured up-front and require no further effort on the user's part. By exchanging messages in a completely anonymous manner, RTI Connext DDS Micro greatly simplifies distributed application design and encourages modular, well-structured programs. Furthermore, RTI Connext DDS Micro includes the following features, which are designed to meet the needs of distributed real-time applications:

  • Data-centric, peer-to-peer publish-subscribe communications - The most elegant, flexible data communications model.
    • Simplifies distributed application programming.
    • Time-critical data flow with low latency.
    • Clear semantics for managing multiple sources of the same data.
    • Efficient data transfer, customizable Quality of Service, and error notification.
    • Notification by a callback routine on data arrival to minimize latency.
    • Notification when data does not arrive by an expected deadline.
    • Ability to send the same message to multiple subscribers on multiple computers efficiently, including support for reliable multicast.
  • User-definable data types - Enables you to tailor the format of the information being sent to each application.
  • Reliable messaging - Enables subscribing applications to specify reliable delivery of samples.
  • Multiple Communication Networks - Multiple independent communication networks (domains) each using RTI Connext DDS Micro can be used over the same physical network. Applications are only able to participate in the domains to which they belong. Individual applications can be configured to participate in multiple domains.
  • Symmetric architecture - Makes your application robust:
    • No central server or privileged nodes, so the system is robust to node failures.
    • Subscriptions and publications can be dynamically added and removed from the system at any time.
  • Pluggable Transports Framework - Includes the ability to define new transport plug-ins and run over them. RTI Connext DDS Micro comes with a standard UDP/IP pluggable transport and a intra-participant transport. New transports can be implemented for a variety of transport mechanisms, including backplanes, switched fabrics, and new networking technologies.
  • Multi-language support - Includes APIs for the C and C++.
  • Multi-platform and heterogeneous system support - Applications based on RTI Connext DDS Micro can communicate transparently with each other regardless of the underlying operating system (UNIX, RTOS, Windows) or hardware. Consult the RTI Supported Platforms section to see which platforms are supported in this release.
  • Dynamic endpoint discovery
    • Topics, subscriptions, and publications can be added or removed from the system at any time.
  • Static endpoint discovery
  • Compliance with Standards
    • API complies with the DCPS layer of the OMG’s DDS specification.
    • Data types comply with OMG Interface Definition LanguageTM (IDL).
    • Data packet format complies with the International Engineering Consortium’s (IEC’s) publicly available specification for the RTPS wire protocol, also available from OMG.
