High availability

No market imposes more stringent requirements for availability than networking and no realtime OS offers more in terms of reliability than the QNX Neutrino RTOS. To further increase availability, QNX Software Systems offers a high availability framework. Using this framework, developers can devise fault recovery scenarios that can execute without a system reboot.

Core OS

Core operating system

The QNX Neutrino RTOS is designed specifically to meet the most demanding reliability and performance requirements. The microkernel architecture incorporates only core functionality into a tiny, well-tested kernel, while leaving drivers, networking stacks, and other services outside in memory-protected space. This creates the ideal foundation for 99.999% reliability.

Security

To address the ever-increasing security threats facing embedded systems, whether they are large distributed systems or small isolated industrial controllers, QNX has advanced security mechanisms that are built directly into the QNX Neutrino RTOS that protect the device from malicious attacks. These can be used to ensure that all processes, including drivers and filesystems, execute in user-mode, greatly reducing the ability of compromised processes. Further, it is possible to divide the filesystem into encrypted domains, as well as to randomize the address space layout for further protection against malicious intent.

The security attack surface of the system can be further reduced by utilizing a unique ability to control settings that govern and protect which operations a process can perform, with granularity down to the system-call level. As a result, embedded developers no longer have to give processes root permissions and access to the entire system in order to gain access to necessary system resources.

Multi-core

Driven by the need for maximum processing power in high-end networking equipment, QNX Software Systems has supported discrete implementations of multiprocessing for over a decade. QNX multi-core technology ships today in many production programs and has been hardened by use in the most demanding applications. Likewise, the QNX Momentics Tool Suite was developed from the ground up with multiprocessing in mind. It's the most sophisticated multi-core development environment available today.

Adaptive partitioning

QNX adaptive partitioning technology is a unique approach that provides CPU resource guarantees to defined partitions, ensuring all system elements have access to critical resources. However, unlike fixed partitioning, it allows partitions to exceed minimum time budgets if spare processing cycles are available. This allows a system to maximize CPU time while ensuring high availability containing DoS attacks, preventing runaway command-line interfaces, and so on.

QNX Software Systems provides a comprehensive suite of natively supported networking protocols based on standard industry implementations. Stacks are pre-integrated and fully tested with the QNX Neutrino® RTOS, allowing developers to reduce development time and accelerate product delivery.

With the QNX Neutrino RTOS, networking protocols execute outside the kernel as separate, memory-protected processes. As a result, developers can combine any number of natively supported networking protocols, including TCP/IP and transparent distributed processing. They can also run multiple applications, such as virtual routing, using a single protocol stack on a single physical box to add incremental security or management for specific applications.

QNX distributed connectivity

Highlights

  • Pre-integration with the QNX Neutrino RTOS to get development teams up and running quickly
  • Additional source code modules for hardware integration and optimization
  • Standard BSD reference implementations and support for current industry standards
  • Support for both IPv4 and IPv6 with a full migration path from IPv4 to IPv6
  • Third-party networking code based on POSIX and BSD APIs

End user demands continue to drive the need for maximum processing power. Silicon vendors, unable to scale exclusively with clock speed, have moved to a multi-core architecture to increase overall performance. While this solves the overall MIPs problem, it introduces a new level of complexity for the networking software developer.

QNX Software Systems is the only RTOS vendor to provide a comprehensive multi-core offering. In fact, QNX has supported discrete implementations of multi-processing for over a decade. This multi-core technology ships today in many production programs and has been hardened by use in the most demanding applications.

The QNX Neutrino RTOS offers three multi-core modes of operation:

  • Asymmetric multiprocessing (AMP) run the QNX Neutrino RTOS on each core using QNX transparent distributed processing as an inter-process communication mechanism or use Transparent Inter-process Communication (TIPC) to communicate between QNX and Linux cores
  • Symmetric multiprocessing (SMP) run a single instance of the QNX Neutrino RTOS to manage thread scheduling and shared resources
  • Bound multiprocessing (BMP) run specific processes tied to individual cores with a single instance of the QNX Neutrino RTOS to manage shared resources

Developers can choose to let some processes run in SMP mode while using BMP to migrate legacy code.

Multi-core tools

QNX Software Systems understands that tools play a critical role in debugging and optimizing complex networking applications. Thats why the QNX Momentics® Tool Suite was built from the ground up to support multiprocessing. It is, in fact, the only fully multi-core-aware tool suite available today. It offers highly advanced visualization tools such as application and system profilers, which allow developers to indentify code that can benefit from multi-core processing and to get a thread-level view of system performance.

Networking developers want the self-sufficiency and code access that comes with an open source model, but they also understand the benefits of a commercially supported offering - quality product management, published roadmaps, IP protection, and professional support.

QNX Software Systems understands this dichotomy and has created a new hybrid software model that combines the best of both worlds, providing the flexibility of the open source model with the benefits of a commercially supported solution. Highlights include:

  • Availability of all QNX source code at no charge
  • Professional support and access to QNX engineers who write QNX code
  • Simplified engagement model for prototyping phase of project development
  • Clean intellectual property and non-viral licensing model

The professional services team of developers, engineers, and architects can help dramatically improve system performance using multi-core optimization techniques and visualization tools.

Porting from Linux

Network equipment manufacturers are increasingly interested in the benefits of realtime computing for achieving 99.999% reliability. Customers porting Linux applications to the QNX Neutrino® RTOS find it surprisingly straightforward (since both use the POSIX API), however they also find porting low-level Linux drivers (to any OS) to be a bit more challenging. QNX Professional Services keeps a smooth migration path while ensuring ported applications are fast, reliable, and maintainable.
