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.

Unfortunately, wired networking equipment and wireless networking equipment have traditionally operated in separate realms, with inconsistent features, policies, tools, and management. This increases the network administrator’s burden and drives up management costs and complexity. Cisco has recently released a new set of unified networking and management platforms designed to bring consistency and continuity to all aspects of the campus network, from the wiring closet to WLAN controllers — and everything in between. By implementing such an architectural approach to unifying wired and wireless networks, IT and network managers can introduce new levels of efficiency, gain greater levels of manageability, and improve user experience. Enabling greater levels of business innovation and growth while controlling costs, IT can demonstrate how it is driving innovative value-add to the business.

IT business leaders are seeking data center fabrics that scale to support increasing density of physical and virtual servers at cloud spec. In October of this year, Cisco delivered a monster data center fabric announcement aimed at increasing scale, security and new data center services. A few highlights are the second-generation Nexus 7000 capabilities, a new Nexus 7009 platform, plus FabricPath capabilities on the Nexus 5500 and expanded Nexus 1GbE and 40GbE form factors of the Nexus 3000. Shashi Kiran, Director of Market Management for Data Center/Virtualization and Enterprise Switching at Cisco Systems joins me to talk about what IT business leaders will gain from this new announcement from a business outcome and data center fabric design perspective.
