With the ever-growing use of global Internet devices and the uneven distribution of network addresses, certain large organizations and geographic regions are experiencing a shortage of unique IP addresses. IPv6 uses a 128-bit address field, which provides room for 3.4*(10^38) 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 optimized for performance-critical embedded devices. Its modular architecture allows designers to customize various components based on their system requirements. NetX Duo APIs are fully backward compatible with the IPv4 services in NetX. Therefore existing NetX applications can be migrated to NetX Duo with minimal porting effort. NetX Duo has been tested for RFC compilance using the TAHI test suite (phase 2). This ensures that NetX Duo conforms to RFC standards and offers complete interoperability with devices from other vendors.
NetX Duo implements the following protocols and RFCs
All IPv4 features available in NetX 5.x
IPv6 header and extension header processing
Neighbor Discovery Protocol
Router Discovery Protocol
Stateless Address Autoconfiguration
Duplicate Address Detection
RFC2460: Internet Protocol, Version 6 (IPv6) Specification
RFC2461: Neighbor Discovery for IP Version 6
RFC2462: IPv6 Stateless Address Autoconfiguration
RFC2464: Transmission of IPv6 Packets over Ethernet Networks
RFC4291: Internet Protocol Version 6 (IPv6) Addressing Architecture
RFC4443: Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification
Thanks to implementing the IPv6 protocol, NetX Duo also enjoys several new capabilities. For the first time, nodes can configure their interface addresses automatically through the Stateless Address Autoconfiguration protocol. As well, nodes can use layered structures to enable devices to more efficiently process IPv6 headers. NetX and NetX Duo are available immediately from Express Logic, with license prices starting at $12,500 for NetX and $18,750 for NetX Duo, with no run-time royalties.
