Architecting Resource-Constrained Systems

Connext Micro provides a small-footprint connectivity framework for autonomous systems that have minimal memory and CPU power, and that may not even have an operating system. 

  • Meets stringent size, weight, and power requirements with performance, scalability and reliability well beyond the reach of traditional connectivity frameworks.
  • Satisfies demanding real-time performance requirements while meeting stringent resource constraints.
  • Reduces development costs to minimize the amount of custom connectivity or integration code developers would otherwise have to create.



A high-level and standards-compliant alternative to in-house development.

Decentralized System Architecture

An innovative, completely decentralized architecture enabling applications to directly exchange data in a true peer-to-peer manner, eliminating bottlenecks from message brokers or daemon processes as well as any single point of failure.

Highly Portable

Applications can be implemented on platforms with minimal operating system capabilities or no operating system at all, without built-in dependency on operating system services.

Deterministic Resource Utilization

All memory utilization is fixed based on resource constraints. No dynamic memory allocation is required. Efficient serialization and compact wire representation minimize CPU and network overhead.
