Application Downtime Performance of Cisco WLC Code Versions
Conclusion
Our performance testing, while not exhaustive, verifies that Cisco’s Stateful Switchover (SSO) is
effective in rapidly restoring wireless LAN services in the event of a controller failover. We measured
reductions in application downtime of between 92 and 98 percent compared to earlier product
offerings. Measurable application downtime was always less than a second, a marked improvement
from earlier failover services.

As Enterprise Wi-Fi systems continue to mature and improve, employing more sophisticated
architectures that improve security, management, performance, and resiliency. Cisco’s focus on
improving application failover through its newly enhanced SSO offerings represents a behind-the-
scenes improvements that most network managers hope they never need to take advantage of. This
is indicative of the evolution of wireless network services. The easiest problems have already been
solved, allowing Cisco and other vendors to concentrate on more subtle enhancements that allow
enterprises to approach availability levels traditionally associated with wired networks.
