Application Scenarios for IP FPM

Application Scenarios for IP FPM

End-to-End Packet Loss Measurement

In Figure 4-6, the target flow enters the network through RouterA and leaves the network through RouterB. The target flow enters the network through one interface and leaves through another interface. IP FPM end-to-end packet loss measurement can be deployed on RouterA and RouterB to measure the packet loss rate on the network.

Figure 4-6  End-to-end packet loss measurement (1)

In Figure 4-7, all Huawei devices form an end-to-end network. The ingress and egress interfaces of the target flow reside on multiple network edge devices. The number of all packets entering the network should be the same as the number of packets leaving the network. IP FPM end-to-end packet loss measurement can be deployed on RouterA, RouterB, RouterC, and RouterD to measure the packet loss rate on the network.

End-to-End Delay Measurement

In Figure 4-8, a specified service flow is forwarded from RouterA to RouterB and from RouterB to RouterA on an end-to-end network. In IP FPM, a device samples service packets, records the actual forwarding time of service packets, and calculates the transmission delay of the service flow.
