Product Description

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.


TCP/IP stack model
  • Built-in support for multiple network interfaces
  • 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 ACK and congestion control
  • Raw socket interface
  • Multicast support (IGMPv2 and MLDv1)
  • IP fragmentation and reassembly support
  • Flexible memory footprint
  • High throughput
  • Dialog-based configuration wizard
  • Portable architecture (no processor dependencies)
  • Straightforward port to any RTOS
  • Debugging and trace functionality to ease development and integration
  • Host name resolution (DNS, mDNS and NetBIOS Name Service)
  • mDNS and NetBIOS responder
  • DNS-based service discovery (DNS-SD)
  • Auto-IP (dynamic configuration of IPv4 link-local addresses)
  • DHCP client and DHCP server
  • SLAAC (IPv6 stateless address autoconfiguration )
  • DHCPv6 client and DHCPv6 relay agent
  • FTP client
  • Secure FTPS client (both implicit and explicit security modes supported)
  • FTP server
  • MQTT v3.1.1 client (TCP, SSL/TLS, WebSocket and secure WebSocket transport layers supported)
  • Web server with SSI, CGI scripting and WebSocket support
  • Secure Web server (HTTPS)
  • SMTP client
  • Network time synchronization (SNTP client)
  • SNMPv1/SNMPv2c/SNMPv3 agent (MD5/SHA-1 authentication and DES/AES privacy protocols are supported)
  • TFTP client and TFTP server
  • WebSockets client and server API (WebSocket connections tunneled over SSL/TLS supported)
  • PPP (Point-to-Point Protocol)

Feature Comparison

The TCP/IP stack is available either as open source (CycloneTCP Open) or under a commercial license (CycloneTCP Lite, Pro or Ultimate) for proprietary developments in a commercial context:

  • The open source version CycloneTCP Open is available for free. Developers must freely distribute the complete source code of their application, making it available for end users.
  • The commercial version CycloneTCP Lite includes all the core features of the IPv4 stack but does not provide any application protocols. This version targets developers who only need access to sockets.
  • The commercial version CycloneTCP Pro is a full-featured IPv4 stack. This version includes application protocols such as FTP, HTTP, MQTT, SMTP, SNMP, SNTP and TFTP.
  • The commercial version CycloneTCP Ultimate is a full-featured dual stack (IPv4 and/or IPv6). This version includes application protocols such as FTP, HTTP, MQTT, SMTP, SNMP, SNTP and TFTP.
