Cisco VoIP Phone
Rather than the traditional PBX system, enterprise industries trend to invest in a more flexible and cost
effective Voice over IP system as their means of communications within and outside their network.
After Installing the Call Manager Express version 4.1 on the Cisco ISR 2811 router and integrating it to
the network, we connected a Cisco 7960 IP phone on SCCP Firmware file Version 7.x on the wired
network and the Cisco 7921G wireless IP phone on SCCP Firmware file Version 8.x through the Wireless
network using the PEAP authentication protocol. We then initiated a call between the two phones to
test the effects of the failover.

Citrix XenDesktop
Citrix XenDesktop has achieved increasing popularity within enterprises in recent years as a
mechanism for remotely delivering application services. XenDesktop provides location and device
independent secure virtual desktop and application services to users. As a network-intensive service,
it is highly sensitive to performance issues. To test failover with this application, we configured one
wireless client to stream HD 1080p video through the Citrix VDI session.

Windows File Transfer
File Transfer between two Windows PCs happens every day in enterprise wireless networks. In this test,
we configured one client to copy a 40 GB shared folder from the vCenter Server (connected to the
switch through wire). Continuous file transfer was taking place between a wireless client on the same
network.

For each application, to test the result failover on application performance, we simulated failover by
pulling the plug off of the primary controller while the applications were running.

Results
The following tables and graphs show the application downtime as well as ping drops experienced
by the clients in the event of primary controller failure for three WLC software code versions that
feature different types of failover mechanisms.
