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] Such as 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.

[0100] Table 1

[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 st...

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] Such as 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 OA...

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] Such as 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.

Abstract

The invention discloses a monitoring method and device for a bearer network. Wherein, the method includes: generating a first operation management and maintenance OAM message for monitoring the service bearing quality from the local end to the opposite end; and combining the first operation management and maintenance OAM message with the first operation management and maintenance OAM message for carrying the service from the local end to the opposite end. IP service packets are aggregated; the aggregated packets are sent to the opposite end, where the aggregated packets are used to enable the opposite end to determine the service bearing quality from the local end to the opposite end. The present invention solves the technical problems in the related art of inconvenient monitoring and low monitoring accuracy due to the need to consider the networking conditions of the bearer network when monitoring the bearer quality of the bearer network.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a monitoring method and device for a bearer network. Background technique [0002] With the deployment and development of services such as 3G (Third Generation Mobile Communications) and Long Term Evolution (LTE for short), data services have become the main bearer, and their demand for bandwidth is growing rapidly. Packetized bearer networks Construction has become an irreversible trend. However, after the bearer network is packetized, its bearer quality, including delay, connectivity, and packet loss, needs to be monitored in real time. For this reason, the packetized bearer network supports a large number of Operation Administration and Maintenance (Operation Administration and Maintenance, referred to as for OAM). Although there are many types and levels of OAM supported, there is no end-to-end accurate OAM monitoring for the IP service layer, which is not very convenient...
