Abstract
Intel Corp. commissioned The Tolly Group to benchmark the performance of several commercially available 802.11 wireless gateways (wireless broadband routers and access points) that utilize the Intel® IXP425, IXP422 and the IXP420 network processors, and compare the performance of those devices against other, generally available products based upon alternative chipsets.
Tolly Group engineers used the industry-accepted IXIA IxChariot’s “throughput.scr” script to determine the aggregate application throughput of the devices under test. Tests were performed using the standard script provided by IxChariot version 4.3, “throughput.scr” with 1-MB file size under identical test conditions with the clients running IxChariot Performance Endpoint version 4.5. Tests were conducted with three data traffic scenarios (1) upstream (2) downstream and (3) bidirectional in network topologies of WLAN-to-LAN, WLAN-to-WAN and Wireless Distribution System (WDS).
Engineers measured application throughput for devices supporting 802.11g and 802.11b wireless standards. Extensive testing was conducted during May 2004. Test results show that the wireless gateways based upon the Intel IXP425, IXP422 and IXP420 either outperform competitive products in every scenario, or provide performance on par with other devices.
