NQA applications.

Performing Network Diagnosis

You may often encounter such problems as intermittent network disconnections, failure to access websites, slow Internet access, and slow file downloading. When this occurs, you need to collect statistics about the device to locate the faults. These statistics need to be provided by the device.

Figure 14-34 Performing network diagnosis

As shown in Figure 14-34, users in different places connect to each other over a VPN network. However, users reflect that the network is disconnected intermittently and the network connection is slow.

You can deploy NQA on PEs to analyze network quality. Perform an ICMP test between the PEs and CEs to check the continuity of the network. After confirming that the network is correctly connected, perform a jitter test to measure the network jitter. Then perform the same tests between the PEs. Analyze the test data and the faults that users encounter for fault location.

Learning About Network Service Quality

As shown in Figure 14-35, users can perform an NQA test on the Switch Module device to obtain statistics about the network operating status, which helps learn about network service quality.
