iFIT Applications on an EVPN VPWS

On an EVPN VPWS, you can configure iFIT measurement points, in end-to-end or hop-by-hop mode, to monitor network performance. You can deploy iFIT on an EVPN VPWS as follows:

1. Deploy an EVPN VPWS, and import private network traffic to the ingress.
2. Configure the ingress as an iFIT measurement point from which the measurement starts.
3. Set other measurement points based on the statistics collection mode.
   • End-to-end statistics collection: Only the egress is configured as the iFIT measurement point to collect performance statistics.
   • Hop-by-hop measurement: iFIT measurement points are configured on each node that traffic passes through to collect performance statistics.
4. Each measurement point reports the statistics to the NMS. Users can view the statistics on the GUI.

iFIT is supported in EVPN VPWS single-homing, dual-homing single-active, and dual-homing all-active scenarios.

Figure 1 shows the typical networking of iFIT end-to-end performance measurement on an EVPN VPWS. iFIT measurement points are deployed on the ingress and egress of the EVPN VPWS to monitor network performance in real time.

Figure 2 shows the typical networking of iFIT hop-by-hop performance measurement on an EVPN VPWS. iFIT measurement points are deployed on nodes through which traffic passes on the EVPN VPWS to monitor network performance in real time.

After iFIT is deployed, it measures the packet loss and delay of service packets on the EVPN VPWS in real time. This allows customers to promptly adjust services when network performance deteriorates.
