Application Performance Visibility with WAN Optimization

Topology

Figure 6 shows the topology for measuring and managing application performance across various network

segments.

Figure 6. Topology for Measuring and Managing Application Performance Across Network Segments

Cisco Performance Agent is used as an application performance data source from the branch-office router. Cisco

Flow Agent is used as an application performance data source from the Cisco WAAS appliance in the data center.

The Cisco Prime NAM in the data center correlates metrics from all sources and presents the overall application

performance report. As part of the initial WAAS deployment lifecycle, the NAM can report on traffic for application

response time (latency) trends through the Cisco Performance Agent. This information helps with short listing

candidate applications or servers for WAAS optimization. Cisco WAAS is deployed after a site is selected with a

baseline of an application or server measured with the NAM. With WAN optimization service turned on in the

branch office and data center, application performance is measured and reported in the NAM, helping users to

analyze the effect of WAN optimization. Data measurements are used to ensure service-level agreements (SLAs)

for the application delivery are met.

Cisco Performance Agent Data Source Configuration in the Branch-Office Router

The following configuration will send traffic in pass-through mode without WAN optimization on the branch-office

router:

paramater-map type waas waas_global

no tfo optimize
