ESC – NetX Duo IPv6 TCP/IP stack passes IPv6 Ready Logo testing


San Jose, Calif. – The NetX Duo dual IPv4/IPv6 TCP/IP stack from Express Logic, Inc., (ESC booth 1128) has successfully passed rigorous IPv6-Ready Logo testing. The IPv6 Forum, a world-wide consortium focused on providing technical guidance for the deployment of IPv6, does not allow companies to post the IPv6 Ready Logo until conformance and interoperability testing is complete in order to increase user confidence by demonstrating that IPv6 is available now and ready to be used.

IPv6, the latest standard set by the Internet Engineering Task Force (IETF), expands and supplements the capabilities of IPv4. IPv6 uses a 128-bit address field, which provides 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 a dual IPv4 and IPv6 TCP/IP stack, it can handle both IPv4 and IPv6 protocols and is highly optimized for performance-critical embedded devices. Its modular architecture lets designers customizes various components based on system requirements. NetX Duo APIs are fully backward compatible with the IPv4 services. NetX Duo answers the need for expanded IP capabilities while also supporting legacy needs at the same time.

To obtain IPv6-Ready Logo certification, a network stack must pass conformance and interoperability tests administered and validated by the IPv6 Forum. There are two phases of testing, Phase-I and Phase-II. Phase-I is relatively basic and limited to verification of select IPv6 capabilities. Phase-II is much more rigorous and extensive, and is a superset of Phase-I.

Express Logic chose to seek Phase-II approval, which required NetX Duo to pass a challenging set of 373 test cases, which cover the following RFCs: RFC 2460, IPv6 Specification; RFC 4861, Neighbor Discovery for IPv6; RFC 4862, IPv6 Stateless Address Autoconfiguration; RFC 1981, Path MTU Discovery for IPv6; and RFC 4443, ICMPv6.

The Phase-II Interoperability tests ensure that the implementation is able to work with other devices and routers. This test requires setting up a test network with multiple routers and hosts, and to validate that NetX Duo follows the IPv6 standard and correctly interacts with other hosts and routers. NetX Duo successfully performed these tests to receive its official IPv6-Ready Logo certification.

“Many government agencies require that all Internet-capable devices have IPv6 support. Our IPv6 Ready Logo validation and certification will go a long way toward ensuring that embedded devices'are readily accepted and easily implemented throughout the world,” commented William E. Lamie, president of Express Logic.

NetX Duo is available immediately from Express Logic, with license prices starting at $18,750, with no run-time royalties.
