IPv4, IPv6 dual stack for embedded networking

19 March 2008 Telecoms, Datacoms, Wireless, IoT

Express Logic has announced the availability of NetX Duo, its new dual IPv4/IPv6 TCP/IP stack. NetX Duo is built upon the solid field-proven foundation of Express Logic’s NetX TCP/IP stack, an IPv4-only solution. Now, as developers recognise the greatly expanded demands of Internet enabled devices, NetX has been extended to support IPv6 as well.

IPv6, the latest standard set by the Internet Engineering Task Force (IETF), expands and supplements the capabilities of IPv4, particularly in the number of available IP addresses. IPv4 uses a 32-bit field, resulting in just over 4 billion unique IP addresses. With the ever-growing use of global Internet devices and the uneven distribution of network addresses, certain large organisations and geographic regions are experiencing a shortage of unique IP addresses. IPv6 uses a 128-bit address field, which provides room for 3,4 x 1038 unique addresses, more than enough for every person to own thousands of addresses and for every device to connect directly to the Internet.

Because NetX Duo is an IPv4 and IPv6 dual TCP/IP stack, it can handle both IPv4 and IPv6 protocols as well as being highly optimised for performance-critical embedded devices. Its modular architecture allows designers to customise various components based on their system requirements. NetX Duo APIs are fully backward compatible with the IPv4 services in NetX, so that existing NetX applications can be migrated to NetX Duo with minimal porting effort.
