address specific developer issues such as ATM connectivity, Intel helps customers focus on product differentiation and the integration of value-added features and services, while saving both time and money.
Using the Example Design
Intel develops software example designs to demonstrate the flexibility and capabilities of the IXP1200 network processor family and its associated development environment. The ATM/OC-3 to Fast Ethernet IP Router Example Design consists of licensed royalty-free code that demonstrates how the IXP1200 network processor can be used to bi-directionally route IP packets between ATM and Ethernet networks. This example design is intended as a convenient starting point for customers designing similar applications, while providing a demonstration of the functionality and performance capabilities of the IXP1200 network processor.
The example code is part of a comprehensive development environment and is designed to run on the Intel® IXDP1200 Advanced Development Platform, or on the customers' hardware. Developers can modify the code, add additional proprietary value-added modules, and use the example design to estimate application performance. ATM/OC-3 to Fast Ethernet IP Router Example Design demonstrates one of several possible software architectures that enable the IXP1200 network processor to be used in ATM/Ethernet designs.
