The Fusion TCP/IP Stack protocol suite provides developers a highly portable, embedded source code stack designed specifically for embedded applications. With its 20-year history, the Fusion Embedded TCP/IP Stack is the most widely used network protocol stack in the world with thousands of design wins and millions of Fusion Network-enabled products shipping. The basic Fusion embedded TCP/IP stack includes source code for TCP, UDP, IP, ICMP, ARP, RARP, TFTP, BOOTP and IGMPv2. Optional security may be added to Fusion TCP/IP with IPsec.
