Aruba also improved the software's capabilities to speed up recovery from a network failure, including Wi-Fi clients being able to keep connections and application sessions. The faster recovery means clients don't drop their connection and start searching for a new SSID. From the end-user's viewpoint, says Dondurmacioglu, "the Wi-Fi link never drops." TCP/IP applications "take a quick pause" and then continue to function. This is true even for time-sensitive applications like video conferencing, voice, and other real-time applications.
Aruba tested the new firmware released in a variety of settings, pitting the Aruba AP-135 against the Cisco 3602i access point, in a set of tests with a mix of Wi-Fi clients. Probably not surprising, the results show the Aruba gear maintaining higher throughput and capacity; dropping no Wi-Fi connections or real-time application sessions. The test report, with an explanation of the methodology used, is available online in PDF format.
The ArubaOS 126.96.36.199 release is available now, shipping with new hardware, and a free download to existing customers with support contracts.
