The Intel® Internet Exchange Architecture (Intel® IXA) provides a framework for the design of powerful and flexible networking and communication products. Offering unmatched flexibility and programmable performance, the IXP1200 family provides a total development environment that includes a complete set of hardware and software building blocks and a comprehensive software development tool designed to shorten time-to-market in a wide range of networking applications. One important application segment is network access switching equipment for internetworking between an Ethernet LAN and an ATM WAN.
The example design demonstrates the functionality and performance of the IXP1200 Network Processor family. Specifically, the design shows how ATM-Ethernet internetworking is handled by the IXP1200 Network Processor within the Intel® IXDP1200 Advanced Development Platform. |

The TCP/IP and ATM stacks reside on the Intel® StrongARM* core, of the IXP1200 Network Processor, and the switch contains software-based SAR and CRC functionality in the IXP1200 microengines. The access switch design also includes a Linux application based on the Big-endian Linux release available from the open source community. This Example Design represents one of several possible software architectures that enable the IXP1200 Network Processor to be used in an entry-level ATM-Ethernet switch.
Product Features
- Demonstrates a WAN/LAN access switch solution based on the Intel® IXP1200 Network Processor and other components of the total development environment

Total Development Environment
In addition to the WAN/LAN Access Switch Example Design, Intel® Internet Exchange Architecture (Intel® IXA) offers a comprehensive set of silicon, development tools and software:
- Intel IXP1200 Network Processor Family
- IXDP1200 Advanced Development Platform
- Intel® Internet Exchange Architecture Software Developers Kit (SDK) 2.0
- ATM/OC-3 to Fast Ethernet IP Router Example Design
Next-generation network solutions require faster and more agile development than can be achieved with ASIC-based designs. Intel IXP1200 Network Processor building blocks are designed to work together, providing the faster time-to-market development environment required for next generation Internet applications. In addition to its competitive advantage for equipment manufacturers, this comprehensive development environment reduces development costs for intelligent network products and while helping to reduce the total cost-of-ownership.
