Embodiment 1
[0028] In this embodiment, by adding an auto-discovery parameter synchronization message, the node that stops auto-discovery notifies the peer end of the auto-discovery status of the local end. If the local end or the remote end stops automatic discovery, the local auto-discovery process is stopped.
[0029] Synchronization is performed between two nodes, NODE1 and NODE2. The specific processing flow is as follows:
[0030] Step A: NODE1 sends an auto-discovery parameter synchronization request message to NODE2, which includes the transmission port ID of the node, the transmission port ID of the peer node, and the automatic discovery status of the node;
[0031] The auto-discovery status is used to indicate whether the current node currently starts auto-discovery or not.
[0032] Step B: NODE2 detects the received auto-discovery parameter synchronization request message, and judges that if the auto-discovery status in the message indicates that NODE1 has not started auto-disc...
Embodiment 2
[0039] This embodiment describes the nodes that implement the method in Embodiment 1 above, such as Figure 4 As shown, including the first module and the second module, wherein:
[0040] The first module is used to send an automatic discovery parameter synchronization request message to the second node when the current node is the first node, and the message contains the automatic discovery status of the node; the automatic discovery status is used to indicate that the current node currently starts automatic Discovery or not start auto-discovery;
[0041]The second module is used to detect the received automatic discovery parameter synchronization request message when the current node is the second node, and judge if the automatic discovery status in the message indicates that the first node has not started automatic discovery, and the local end currently starts automatic discovery. If found, the local end stops automatic discovery.
[0042] Preferably, the second module is...

Abstract
The invention discloses a configuration method for synchronous automatic discovery, which solves the problem of link unavailability caused by inconsistency in automatic discovery configuration, and reduces the impact of configuration changes on services. The method includes: the first node sends an automatic discovery parameter synchronization request message to the second node, and the message includes the automatic discovery status of the node; the automatic discovery status is used to indicate whether the current node currently starts automatic discovery or not; The second node detects the received auto-discovery parameter synchronization request message, and judges that if the auto-discovery status in the message indicates that the first node has not started auto-discovery, and the self-end has currently started auto-discovery, then the local end stops auto-discovery. By adopting the method of the invention, the link degradation caused by configuration can be solved. Improve user experience and reduce reporting of inaccurate alarms. At the same time, resource waste caused by inaccurate alarms is avoided.
Description
technical field [0001] The invention relates to an Automatically Switched Optical Network (ASON), in particular to a method for synchronizing automatically discovered configurations. Background technique [0002] Automatically switched optical network (ASON) is an optical transport network that uses the control plane to complete automatic switching and connection control. It is an intelligent optical transmission network composed of optical fiber as the physical transmission medium and optical transmission systems such as SDH and OTN. The architecture of ASON is divided into three planes according to the functions: transport plane, control plane, and management plane. [0003] The control plane is the core of ASON, which consists of a group of control components that provide routing, signaling, and automatic discovery functions, and is supported by a signaling network. Automatic discovery (abbreviated as DA) means that the network can realize the connection relationship be...
