The service level agreement (SLA) is a network performance diagnosis tool. It sends packets between multiple NEs or links to evaluate the network performance.

The SLA has the following advantages:
  • Instructs users to execute network applications based on the evaluation result.
  • Sends notifications to users when faults occur on the network.
  • Evaluates the network performance continuously or periodically.
  • Checks and confirms the service quality, implementing differentiated services.

The SLA has the following functions:

  • Network performance evaluation: The SLA provides dozens of test instances (such as UDP Echo, TCP Connect, HTTP, DNS, and ICMP Jitter), covering many counters such as delay, jitter, and packet loss rate.
  • Compliance: The SLA calculates the compliance based on the configured counters, thresholds, and weights, and displays the result in graphics on the GUI.
  • Threshold alarm: Users can set thresholds for SLA counters based on the site requirements. If a performance counter exceeds the threshold, an alarm is generated.
  • Compliance alarm: If the conformity is lower than the expectation, an alarm is generated.
  • Periodical monitoring: The SLA can periodically monitor a network on the specified date.
  • Measurement result query: Users can query the counter measurement result in any periods and export the measurement result.
