Network Technology Performance Evaluation Cisco Wireless High Availability By Syracuse University’s Center for Convergence of Emerging Networking Technologies (CCENT)
Dramatic improvements in wireless networking combined with an increasingly important role for mobile devices are driving a trend towards Wi-Fi as the primary network access mechanism in many networks. An increasing number of enterprise networks, and especially mission critical networks like healthcare, cannot afford to have application sessions drop. These trends are driving CIO’s and network managers to demand increasing levels of service resiliency. Wireless network vendors are addressing these needs by implementing new capabilities, more intelligent wireless networks that are able to prioritize mission critical traffic and dynamically recover from component failures. Cisco approached Syracuse University’s Center for Convergence of Emerging Networking Technologies (CCENT) to perform a systematic beta test, including before/after benchmarking of several applications, of its newest Wireless LAN Controller (WLC) Software (code version 7.5), which includes a new controller failover feature called Client Stateful Switchover (Client SSO). We tested this new service offering on our wireless testbed that included Cisco 5508 Wireless LAN controllers and the Cisco AIR-2602i access point.
