smxNS offers a clean, modular design that enables embedded developers to easily add networking capabilities to their real-time embedded systems. It is ROMable and reentrant to ensure compatibility with multitasking operating systems. It can be easily ported to a variety of processors and RTOSs.

Prices start at $8,500 and include, unless otherwise indicated: Development kit, project development license, royalty free incorporation license for one developed product with up to 50,000 units produced, source code and 90 days of support. Ask about Function drivers and Device controller drivers. Ask us about our extensive add-on packages and Ethernet drivers.

Because code and data space are at a premium in small embedded systems, smxNS can be configured to use only those clients/servers, protocols, device drivers, and link layers needed by an application. The basic TCP/IP protocol requires only about 25K bytes on most processors. smxNS provides a choice of device drivers that provide support for most popular embedded network controllers, including 100Mb/s Ethernet devices. smxNS supports standard BSD sockets as well as a simpler interface called Dynamic Protocol Interface (DPI).

The basic package includes: TCP/IP, UDP, ARP, RARP, BOOTP, DNS, ICMP, IGMP, and SLIP. Added to this are the client/server protocols: DHCP, TFTP, FTP, and TELNET. Available at additional cost are: email (SMTP, POP, and MIME), NAT, PPP, PPPoE, SNMPv2 & 3, and Web Server.

smxNS is a good choice for small embedded systems requiring simple networking features, but for which small size and high performance are necessities.
