Embodiment 1
[0098] In the online state, the transmitter and reflector work together to monitor IP end-to-end performance in the L2VPN+L3VPN network.
[0099] like Figure 7 In the shown L2VPN+L3VPN network, in this embodiment, the transmitter is embedded on the UNI interface of PE1, and the processing block diagram is as follows Figure 8 As shown, the reflector is embedded on the UNI interface of PE3, and the processing block diagram is as follows Figure 9 shown. The IP OAM message format used in this embodiment is shown in Table 1. It is necessary to monitor the communication between the base station (10.1.1.10) and the serving gateway (Serving Gate Way, referred to as SGW) (30.1.1.2) in the online state. Two-way IP business.

[0101]
[0102] The following describes in detail the implementation process of the IP OAM message as follows:
[0103] (a) Enable the IP OAM packet transmitter function on the UNI interface connected to the PE1 device and the base stati...
Embodiment 2
[0126] In the offline state, the transmitter and reflector cooperate to monitor the end-to-end performance of IP services in the L2VPN+L3VPN network.
[0127] like Figure 7 In the shown L2VPN+L3VPN network, in this embodiment, the transmitter is embedded on the UNI interface of PE3, and the processing block diagram is as follows Figure 8 As shown, the reflector is embedded on the UNI interface of PE1, and the processing block diagram is as follows Figure 9 shown. The IP OAM message format used in this embodiment is shown in Table 1, and it is necessary to monitor the bidirectional IP service bearing quality between the base station (10.1.1.10) and the SGW (30.1.1.2) in an offline state.
[0128]The following is a detailed description of the IP OAM implementation process as follows:
[0129] (a) Enable the IP OAM packet transmitter function on the UNI interface connected to the PE3 device and SGW, and configure the VLAN, DIP (10.1.1.10), SIP (30.1.1.2), DSCP, and IP OAM p...
Embodiment 3
[0145] It is used together with transmitters to monitor the end-to-end performance of IP services in a network enabled with the NNI-LAG function.
[0146] like Figure 10 In the L2VPN network shown, NNI-LAG is enabled between PE1 and PE2. There are multiple Ethernet services in the same pseudowire. NNI-LAG load sharing uses the flow label method. Among the services carried, IP: 10.1. 1.2 and IP: The two-way business between 10.1.1.3 is more important, and it is necessary to monitor the performance of its business packet loss rate and delay.
[0147] In this embodiment, the two transmitters are respectively embedded on the UNI interfaces of PE1 and PE2, and the processing block diagram is as follows Figure 8 shown. The format of the IP OAM message used in this embodiment is shown in Table 2, and it is necessary to monitor the quality of bidirectional IP service bearer between IP=10.1.1.2 and IP=10.1.1.3 in the online state.
