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.
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)
VLAN support (802.1q and 802.1ad)
USB Device RNDIS class driver (for STM32 microcontrollers)
Supported Protocols
DNS client
NetBIOS client and responder
LLMNR client and responder
mDNS client and responder
DNS-SD responder (DNS-based service discovery)
DHCP client and server
Auto-IP (dynamic configuration of IPv4 link-local addresses)
DHCPv6 client and relay agent
SLAAC (IPv6 stateless address autoconfiguration)
Multicast support (IGMPv2 and MLDv1)
FTP / FTPS client and server (implicit TLS and explicit TLS modes supported)
HTTP / HTTPS client
HTTP / HTTPS server with SSI, CGI scripting and WebSocket support
HTTP/2 client (including HPACK compression, server push and https scheme)
MQTT v3.1.1 client (TCP, TLS, WebSocket and secure WebSocket transport layers supported)
MQTT-SN client (UDP and DTLS transport layers supported)
CoAP client and server (DTLS-secured CoAP, Observe and Block-Wise Transfers supported)
SMTP client
SNTP client (network time synchronization)
SNMP agent (SNMPv1, SNMPv2c and SNMPv3 supported)
Remote management of SNMP users and access rights (SNMP-USM-MIB and SNMP-VACM-MIB)
Standard MIBs: MIB-II, IF-MIB, IP-MIB, TCP-MIB, UDP-MIB, SNMPv2-MIB
TFTP client and server
Modbus/TCP client and server (Modbus/TCP security supported)
WebSocket client and server (WebSocket connections tunneled over SSL/TLS supported)
PPP (Point-to-Point Protocol)
Supported Network Drivers
CycloneTCP supports industry-standard microcontrollers with built-in MAC, standalone Ethernet controllers, PHYs, Switches, as well as Wi-Fi modules and Cellular Modems.
