Requirement analysis
The main factors that can affect the performance of the network infrastructure include the following
items:
•
Performance of the link between the core router and Switch A, such as jitter, one-way average
delay, average RTT, packet loss rate, and unreachable rate.
•
Response time and unreachable rate of the core router and Switch A.
•
Performance of the Ecommerce application server, Web server, and name server, such as CPU
usage, unreachable rate, and response time.
To evaluate the network performance, you can configure an SLA as described in
that monitors
and measures the KQI on the target objects.
