eMDI Interaction Process

eMDI Interaction Process

After eMDI is deployed on a switch, the switch periodically reports monitoring indicator statistics and threshold exceeding alarms to the NMS for real-time analysis.

When service quality deterioration is detected, you can obtain packet information about service flows, such as the source and destination IP addresses, and deploy eMDI on the switch directly or through the NMS. Figure 16-4 shows the eMDI interaction process.

Figure 16-4  eMDI interaction process

The eMDI interaction process is described as follows:

  1. O&M personnel deploy eMDI on switches. This is done either directly on the switches or through the NMS.
  2. The switch deployed with eMDI periodically sends monitoring indicator statistics to the NMS through HTTP2+Protobuf interfaces.
  3. The NMS summarizes the monitoring indicator statistics of each switch and graphically displays the monitoring results.
  4. The O&M personnel quickly demarcate the faulty network segment based on the graphical monitoring results.

Statistics about monitoring indicators of target flows are collected by an eMDI instance, which is a basic unit of eMDI. Each eMDI instance is composed of the target flow, monitoring interval, lifetime, and alarm threshold.
