ORYX Embedded

CycloneTCP is a dual IPv4/IPv6 stack dedicated to embedded applications. CycloneTCP conforms to RFC standards and offers seamless interoperability with existing TCP/IP systems. By supporting IPv6, CycloneTCP eases deployment of next-generation Internet. The stack is distributed as a full ANSI C and highly maintainable source code.

CycloneTCP is available either as open source (GPLv2 license) or under a royalty-free commercial license (non-GPL license). We also propose an evaluation license (90-day license in source form) with technical support for an easier onboarding and effective evaluation of our software.

Main features

  • Dual stack (IPv4 and/or IPv6)
  • Built-in support for multiple network interfaces
  • Flexible memory footprint (built-time configuration to embed only the necessary features)
  • Configurable memory model (static memory pool or heap memory allocation)
  • Portable architecture (no processor dependencies)
  • Straightforward port to any RTOS
  • Highly maintainable source code
  • Debugging and trace functionality to ease development and integration
  • BSD style socket API
  • Blocking/non-blocking socket operation and event-driven functions (select and poll)
  • Efficient data transfer through zero copy
  • Well-crafted TCP module with selective acknowledgement (SACK) and congestion control
  • Raw socket interface
  • IP fragmentation and reassembly support
  • Support for virtual interfaces (multiple MAC addresses per physical interface)
  • Support for multi-homed hosts (multiple IPv4 addresses per interface)
  • Ethernet port multiplication using VLAN tagging (SMSC switches) or tail tagging (Micrel switches)
