The following Network Processor Forum (NPF) benchmarks and Tolly certificates verify performance claims for the Intel® IXP2XXX product line of network processors. NPF was organized to establish common specifications to facilitate and accelerate the development of next-generation networking and telecommunications products based on network processing technologies.

Intel demonstrated the first IP forwarding benchmark at full speed OC-192 line rate. Dual Intel IXP2800 Network Processors, configured in an Intel® IXDP2800 Development System, have been certified to forward at full line rate OC-192 full duplex traffic (20Gbps) with zero packet loss for 40 byte IP packets to 9k jumbo frame packets. This benchmark is a compelling demonstration of the performance capabilities of the Intel® Internet Exchange (Intel® IXA) architecture.

The following Tolly test results document the performance capabilities of the Intel® IXP42X product line of network processors.

The Tolly Group benchmarked the performance of several commercially available VPN gateways that utilize the Intel® IXP425 Network Processor, and compared the performance of those devices against other generally available products based upon alternative chipsets. Test results show that the Intel® IXP425-based products outperformed the competitive products in every scenario.

The Tolly Group benchmarked the performance of several commercially available 802.11 wireless gateways (wireless broadband routers and access points) that utilize the Intel® IXP425, Intel® IXP422, and Intel® IXP420 Network Processors and compared the performance of those devices against other generally available products based upon alternate chipsets. Test results show that the wireless gateways based upon the IXP425, IXP422, and IXP420 can significantly outperform the competitive products.
