Embodiment 1

[0034] An embodiment of the present invention provides a fault handling method, which is applied to a first network device. The network device is set to be connected to the first transmission network and to the second network device in the second transmission network. The first transmission network Different from the second transmission network, such as figure 1 As shown, the method includes:

[0035] Step 101: Detect whether the alarm information sent by other network devices in the optical transmission network is received;

[0036] Step 102: If the alarm information is received, generate a delay instruction;

[0037] Step 103: Based on the delay instruction, perform delayed processing on the received alarm information, and send the delayed alarm information to the second network device in the second transmission network.

[0038] In this embodiment, the first transmission network may be an optical transmission network, and the second transmission network may be an Internet...

Embodiment 2

[0050] An embodiment of the present invention provides a fault handling method, which is applied to a second network device, and the second network device is set in a second transmission network, such as figure 2 As shown, the method includes:

[0051] Step 201: link failure information is detected;

[0052]Step 202: Generate a delay instruction based on the link failure information;

[0053] Step 203: Based on the delay instruction, generate a detection instruction after delaying the link failure information for a first period of time;

[0054] Step 204: Perform link detection on the second transmission network according to the detection instruction to obtain a detection result, and perform processing based on the detection result.

[0055] Preferably, before executing step 202 to generate the delay instruction, it may further include: detecting whether the link is restored to normal, and obtaining a first detection result; if the first detection result indicates that the ...

Embodiment 3

[0062] An embodiment of the present invention provides a network device, the network device is set on a first transmission network and connected to a second network device in a second transmission network, the first transmission network is different from the second transmission network ,Such as image 3 As shown, the network equipment includes:

[0063] The first receiving unit 31 is used to detect whether the alarm information sent by other network equipment in the optical transmission network is received;

[0064] The first processing unit 32 is configured to generate a delay instruction if the warning information is received;

[0065] The first sending unit 33 is configured to perform delayed processing on the received alarm information based on the delay instruction, and send the delayed processed alarm information to the second network device in the second transmission network.

[0066] In this embodiment, the first transmission network may be an optical transmission ne...

Abstract

The invention discloses a fault processing method, a network device and a system wherein the method comprises the following steps: determining whether any warning information is received from other network devices in an optical transmission network or not; if some warning information is received, then, generating a delay instruction; and based on the delay instruction, delaying the warning information for a first duration and then, transmitting the warning information to a second network device in a second transmission network.

Description

technical field [0001] The invention relates to transmission technology in the field of network management, in particular to a fault handling method, network equipment and system. Background technique [0002] The backbone basic bearer network is generally divided into two layers for construction and operation and maintenance. The upper layer is the bearer network (IP layer) composed of routers, and the lower layer is the optical transport network (OTN), wavelength division multiplexing (WDM) and other transmission equipment. Transport network (optical layer). The IP layer proposes the optical link connection requirements between nodes to the optical layer, and the optical layer is responsible for providing optical physical links for the IP layer. [0003] At present, an alarm linkage mechanism is configured between the IP layer and the optical layer to realize the joint networking of the IP layer and the optical layer, as well as the rapid transmission of faults from the o...
