For an overview of which processors are supported by USNET, see the Embedded Software CPU Compatibility Matrix. Additional information on GOFAST is also available for the DSTni™ chip.


USNET Email
USNET Email includes support for SMTP, POP, MIME, and DNS Resolver. These protocols enabled any embedded device to send and receive email.

USNET NAT
USNET NAT, which is written based on industry standard (RFC 2663), enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic.

USNET PPPoE
USNET PPPoE is based on a specification (RFC 2516) for connecting the users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem.

USNET SNMPv3 - Simple Network Management Protocol
Includes version 1, 2, and 3 support and a MIB compiler.

Embedded Web Server
Processor, TCP/IP stack, and RTOS indepedent embedded web server with a very small footprint (15K bytes most processors). Supports HTTP, HTML, Java applets, and CGI script.
3rd Party Add-ons

Third party Add-ons

Insignia Solutions - Jeode Embedded JVM
A fast runtime engine that delivers an optimal balance of performance and predictability in a smaller memory footprint. It can execute Java applications on average six times faster than interpretive VMs.

Configuration

Because code and data space are at a premium in an embedded system, USNET can be configured to use only those client/servers, protocols, device drivers and link layers needed by your application. The TCP/IP protocol requires about 25K bytes on most processors.

Network Drivers

USNET provides your choice of device drivers and link layers. Device drivers provide support for most popular network controllers including FAST (100MB) Ethernet devices.

Protocol Interfaces

USNET supports a variety of approaches. Included are a client/server function interface, a Dynamic Protocol Interface (DPI) and BSD sockets.

Client/Server Functionality

USNET provides client/server functionality which enables you to get started quickly using standard protocols in your application.

FTP and TFTP: Client and server example functions provide a framework which allows application-specific use of received data.

Telnet: Client and server example functions provide a framework for your application's use of the Telnet character stream.

DHCP: Client and server are provided. The DHCP client allows your target to automatically configure its network settings on startup. This provides the end-user with the ability to plug in and run. The DHCP server runs on a local network to give clients their network configuration information.

BOOTP: Client provided. Allows the application to bootstrap from a file loaded at start-up.

PING: Example program provided to test network or host connectivity.
