Embodiment Construction

[0019] Embodiments of the present invention provide a fault recovery method, a fault recovery system, and corresponding detection node network equipment and working node network equipment, which will be described in detail below.

[0020] refer to figure 2 , is a schematic flowchart of a fault recovery method in an embodiment of the present invention, including steps:

[0021] A1. The detection node detects and obtains fault information.

[0022] refer to image 3 , the schematic diagram of the first embodiment of the fault recovery system of the present invention, when image 3 When the link shown is faulty, the upstream and downstream nodes node C and node E of the faulty link can detect the link fault through the existing fault detection mechanism. The detection node described above; when a Figure 4 When the transmission plane node shown fails, the control plane node corresponding to the transmission plane node will detect the corresponding failure. At this time, the ...

Abstract

The invention provides a failure recovery method, which comprises: when a failure occurs, a detection node determines the recovery connection of the work connection influenced by the failure; the detection node sends the recovery connection information to the work node corresponding to the work connection influenced by the failure; the work node acquires the recovery connection information and establishes corresponding recovery connection according to the recovery connection information. The invention further provides corresponding failure recovery system, detection node network equipment andwork node network equipment. By the calculating of recovery connection and the informing are performed by the detection node network equipment in concentration, the invention effectively avoids resource conflict, reduces connection return in the network, and reduces network failure recovery time.

Description

technical field [0001] The invention relates to the communication field, in particular to a fault recovery method, a fault recovery system and network equipment. Background technique [0002] Automatic Switched Optical Network (ASON, Auto Switch Optical Network) / Generalized Multi-Protocol Label Switching Network (GMPLS, Generalized Multi-Protocol Label Switch) network introduces the control plane, which transfers some control functions originally implemented by the network management from the management plane to the On the control plane, it gradually develops from the centralized control of the network management to the distributed control of intelligent nodes. At present, the network fault recovery technology generally adopts the method of distributed source node processing. The network node that detects the fault point notifies the information of the fault point to multiple source nodes of the links affected by the fault through distributed control signaling. Compute new...
