TCP/IPv4/IPv6

Fusion Embedded™ TCP/IPv4/IPv6 Networking Stack

Dual Mode Networking Stack with over 25 years of proven performance

Based on the Fusion Embedded Transmission Control Protocol/Internet Protocol (TCP/IP) stack, Fusion Embedded TCP/IPv6 fully supports all of the existing Fusion Embedded features such as zero-copy and flexible device driver support. Developed from the ground up using the same design concepts as Fusion Embedded IPv4, Fusion Embedded IPv6 is fully integrated with Unicoi's IPv4 stack allowing for dual-mode operation and is implemented using no open source code.

Platform-independent

Fusion Embedded IPv4/IPv6 is a highly portable protocol solution written in 100% ANSI C language and is processor, operating system and compiler independent.

High Performance IPv6

IPv6 provides a platform for next-generation internet functionality required by cell phones and other mobile devices, device control and networked entertainment. IPv6 is designed to run well on high performance networks (Gigabit Ethernet, OC-12, ATM, etc.) and still be efficient for low bandwidth networks (wireless). IPv6 includes support for embedded IPv4 addresses to support transition and compatibility with IPv4 and to allow for a gradual and piecemeal deployment with a minimum of dependencies. IPv6 also supports large hierarchical and anycast addresses.

VLAN Support

Fusion Embedded TCP/IPv6 software includes support for IEEE 802.1Q Virtual LANs (VLANs). VLANS provide the ability to:

  • Create virtual network interfaces enabling the segregation of network traffic into VLANs based on IP routing
  • Run multiple virtual interfaces over a single physical interface
  • Provide each virtual interface with one or more IP addresses of its own, which can be obtained from DHCP servers in the corresponding VLAN
  • Operate PPPoE, IPsec, IPv6 and other protocols over 802.1Q VLANs, enabling true virtual networking
