Extreme Networks has embedded Layer 7 performance into its latest Gigabit Summit switch and is claiming a tenfold improvement in application-aware performance over software-based switches, writes Eric Doyle.

The SummitPx1 is aimed at enterprise and service provider datacentres where current attempts at Layer 7 support are based on a best-effort service or on specific software modules.

The best-effort network is prone to cutting off users or giving slow responses from popular sites. This is eased by implementing server load balancers, but these lack the scalability of custom software, said Extreme.

The switch detects applications, assigns network resources and tracks how much should be charged and who should be billed.

SummitPx1 performance has been confirmed by Mier Communications' independent test centre. Tests produced figures of over 120,000 Layer 7 new user connections - almost 10 times the figure given by competitor Nortel Alteon Aceswitch 184. However, Nortel's test figures are open to interpretation because it failed to supply support details for optimum settings before the tests were run.

Extreme describe SummitPx1 as an application switch. It said the introduction of video streaming and other bandwidth hungry applications will increase the demands on datacentres, which can be alleviated by tailoring responses to the nature of the application.
