eMDI in Rosen-MVPN Scenarios
On the Rosen-MVPN network shown in Figure 1, the eMDI detection solution can be deployed on all CEs and PEs so that service packets passing through all of these nodes can be detected in real time for IPTV video quality monitoring and fault locating.
With the eMDI detection solution deployed, the quality indicators (such as packet loss rate, packet disorder rate, and jitter) of real service packets that pass through the CEs and PEs on the Rosen-MVPN network are detected in real time and the detection results are sent to the NMS on a regular basis. The analysis result of the NMS can be displayed in a trend chart.
When a fault is detected using eMDI on a network node, the detection data on upstream and downstream nodes can be compared to demarcate the faulty network segment. Other methods can be used together to rapidly locate the fault and restore services.
