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.

- 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
