Embodiment 1

[0038] See figure 2 , the embodiment of the present invention provides a method for transmitting an OAM message, the main flow of the method is as follows:

[0039] Step 201: The MEP in the virtual home MEP determines whether the MEP is the master node. Wherein, when it is determined that the MEP is the master node, that is, when the determination result is Yes, step 202 is performed; when it is determined that the MEP is not the master node, that is, when the determination result is No, step 203 is performed.

[0040] See image 3 , is a schematic diagram of a transmission channel of an OAM packet. image 3 2 and 3 in represent a MEP respectively, and these two MEPs form the virtual home MEP, namely image 3 In the figure, the virtual home MEP includes two MEPs as an example. However, the virtual home MEP in the embodiment of the present invention is not limited to consist of only two MEPs, and may include multiple MEPs. image 3 2 and 3 are inside the dashed box in , i...

Embodiment 2

[0070] See Figure 4A , an embodiment of the present invention provides an apparatus for transmitting an OAM message, and the apparatus can be applied to one MEP in a virtual home MEP. Preferably, the device may be the MEP itself. The apparatus may include a determination module 401 and an operation module 402 .

[0071] The determining module 401 may be used to determine whether the MEP is the master node.

[0072] The operation module 402 may be configured to generate and send a first OAM message to the receiving end after the MEP is determined to be the master node; wherein, the virtual home MEP includes at least two MEPs, and the attribute parameters of each MEP are the same.

[0073] Optionally, the device may further include a receiving module.

[0074] The receiving module may be configured to receive the second OAM message from the receiving end.

[0075] Optionally, the operation module 402 may also be configured to send the second OAM message to the master node i...

Embodiment 3

[0083] The embodiment of the present invention also provides an apparatus 500 for transmitting an OAM packet. In the embodiment of the present invention, the apparatus 500 can be applied to one MEP in the virtual home MEP. Preferably, the device may be the MEP itself.

[0084] Such as Figure 5 As shown, the device 500 includes: a bus 540; and a processor 510 connected to the bus 540, a memory 520, and an interface 530, wherein the interface 530 is used to send the first OAM message to the receiving end; the memory 920 is used to store instructions The processor 910 is configured to execute the instruction to determine whether the MEP is a master node; the processor 910 executes the instruction to generate the first OAM message when it is determined that the MEP is the master node; The processor 910 executing the instruction is further configured to forbid generating the first OAM message when it is determined that the MEP is not the master node.

Abstract

The invention discloses an OAM message transmission method, namely a method of implementing client layer OAM for a server layer in dual-homing scenarios. The method includes: determining whether one MEP in virtual homing MEPs is a master node or not; when the MEP is determined being the master node, producing and transmitting a first OAM message to a receiving terminal; when the MEP is determined being not the master node, forbidding the production of the first OAM message. The virtual homing MEPs include at least two MEPs having same attribute parameters. The invention further discloses an OAM message transmission device.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for transmitting OAM messages. Background technique [0002] In the PTN (Packet Transport Network, packet transport network) network, MPLS (Multi-Protocol Label Switching, multi-protocol label switching) is a fast data packet switching and routing system based on label switching, which can be used to realize fast forwarding of packet services . A packet network usually adopts a dual-homing method, such as figure 1 As shown, service connections or channels are respectively established between NE A, NEs B and C. When NE B is valid, NE A can transmit services through NE B. When NE B fails, NE A can Service transmission is performed through network element C. Therefore, under normal circumstances, only services are transmitted between A and B, and the channel between network elements A and C can be regarded as the protection path of the working channel b...
