High Availability and Enterprise-Ready Robustness

RTI Product Tour

When you choose RTI Data Distribution Service, you are choosing the tested, hardened solution proven in hundreds of the most demanding systems on the planet, from warships to trading systems to medical devices. Continue reading to learn more about some of the unique benefits and capabilities of RTI Data Distribution Service.

Data Durability and High Availability

RTI Data Distribution Service delivers high reliability and availability with:

• Durable communication to support late-joining and/or intermittent data consumers.
• Support for redundancy—of data producers, consumers, and communication paths—and for automatic failover among them. There is no single point of failure in your distribution infrastructure.
• Persistent messaging to prevent data loss in the event of component-level or even system-level failures. Learn more about RTI Persistence Service.
• A smart protocol featuring configurable timeouts and retries and intelligent switching between multicast and unicast transmission. Avoid acknowledgement storms and mitigate the effect of slow consumers on the rest of the system.

Rapid Fail-Over for Continuous Availability

In the real world, sometimes systems go down. Fortunately, in a system based on RTI Data Distribution Service, you have built-in support for fail-over and recovery.

• Multiple layers of hot-hot backups: From support for redundant network connections to priority-based fail-over among redundant data producers (based on the DDS concept of data ownership), tools for seamless availability are built in. Furthermore, these capabilities are entirely configuration-driven, which means you can monitor and tune them without modifying or redeploying your application code.
• Extensible behavior: Sometimes you need to do it your way. As data producers and consumers join and leave the network—whether deliberately or as a result of failures—you'll receive detailed notifications. By responding to these, you can adapt your behavior dynamically at run time.

In the demonstration midway through the video, about 90 seconds in, you'll see the use of two quality-of-service (QoS) parameters: ownership and deadline. The former indicates whether subscribing applications should accept data from multiple publishers of the same data (shared ownership) or only one (exclusive ownership). The latter controls how quickly a fail-over from one exclusive owner to another should occur. You can set these QoS parameters—and many others—dynamically in your application code, or you can place them in a configuration file for easy maintenance.

Safety and Security

RTI is serious about security.

• Secure platforms protect your data processing logic. In addition to SELinux and Solaris with Trusted Extensions, RTI supports a variety of high-assurance embedded operating systems.
• A secure architecture avoids whole classes of security breaches. Other products require that you have special trusted nodes on your network or that you grant root administrative access to message-brokering daemon processes. These choke points can be exploited to grant enhanced privileges to unauthorized code. With its peer-to-peer architecture, RTI Data Distribution Service avoids these vulnerabilities: information flows directly from its producer to its intended recipients.
• Data encryption protects your data en route.
• Trusted advisors help you design and deploy the right solution. RTI offers a Security Architecture Assessment to help you evaluate your security needs and avoid potential flaws or costly redesigns.

In addition to the security capabilities built into its entire product line, RTI offers RTI Data Distribution Service, Safety-Critical Edition for users with safety-assurance requirements. Safety-Critical Edition is offered in conjunction with the RTI Safety-Critical Architecture Assessment and RTI's engineering and certification services. The software can be tailored to your specific requirements, easing both development and certification.
