Problems solved by technology

exist figure 2 In the hierarchical VPLS network shown, there is a point-to-point OAM alarm mechanism between UPE and NPE, and between NPE and NPE, but the OAM alarm information between UPE and NPE cannot be notified to other NPE devices. OAM alarm information between NPEs cannot be transmitted to other UPEs

Embodiment Construction

[0029] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] image 3 It shows a schematic flow chart of an embodiment of the alarm information transmission method in the present invention, including the following steps:

[0031]Step S3001: The network device at this layer generates corresponding alarm information in the first format according to the condition of the received message.

[0032] in such as figure 2 In the shown network, VPLS is divided into two levels of networks: the core layer and the aggregation layer. In the embodiment of the present invention, the network at this layer is not limited to the core layer, and the network at the lower layer is not limited to the convergence layer. For the convenience of description, the embodiment of the present invention takes the core layer and the convergence layer as examples for description.

[0033] The core layer and the aggregation laye...

Abstract

The invention discloses an alarm information transmitting method, which achieves the alarm information transmitting between current layer and lower layer of VPLS that adopts different protocol via the format conversion of the alarm information, i.e. the alarm information of the lower layer network can be transmitted to other network devices in current layer through the alarm format conversion, also, the the alarm information of the current layer network can be transmitted to network devices in lower layer through the alarm format conversion. The invention further discloses an alarm information transmitting device, and a network device thereof. The invention realizes the OAM function from end to end in multilayer VPLS netwrok.

Description

technical field [0001] The invention relates to the field of Ethernet communication, in particular to a method, device and network equipment for transmitting alarm information. Background technique [0002] Ethernet technology has the characteristics of low cost, easy to use, etc. It occupies a large share of today's local area network technology, and is gradually developing towards metropolitan area network and wide area network. It is becoming an emerging and important metropolitan area network solution. Virtual private LAN service (Virtual Private LAN Service, VPLS) technology belongs to two-tier virtual private network (Laycr2 Virtual Private Network, L2VPN), which is transparent on the network or IP network based on multi-protocol label switching (MultiplcProtocol Label Switch, MPLS) Pass user's Ethernet data. [0003] The current network structure is generally layered and hierarchical, such as figure 1 As shown, end users purchase services from service providers to ...
