Problems solved by technology

In the current network management system, the configuration of optical layer services is not completely implemented and managed according to the standard three levels, which makes the upper layer integrated network management of operators such as telecom and the centralized controller in the new SDN network architecture have to deal with The optical layer service data is processed complexly, converted into a common data structure, and then the services of various manufacturers are connected in series, which greatly reduces the user experience

Embodiment 1

[0077] see figure 1 As shown, the embodiment of the present invention provides a method for configuring a layered model of an optical layer service in a network management system, including the following steps:

[0078] Step A, collect WDM, OTN, POTN three types of nodes in the communication network, and the topological connections between each node and within the node;

[0079] Step B, collect the optical ports on the optical layer signal processing unit disk in each node, and generate logical point objects at three levels: optical transmission section OTS, optical multiplexing section OMS, and optical channel OCH;

[0080] Step C, analyzing the logical point objects under the optical port, and generating cross-connects in a single disk at two levels of OMS and OCH;

[0081] Step D: Create subnet connections in the network element and end-to-end OTS, OMS, and OCH layers layer by layer, and download the optical layer cross-connection configuration to the device through the es...

Embodiment 3

[0121] On the basis of Embodiment 1, the topological connection between nodes in step A refers to the optical fiber connection between two adjacent nodes, which will be displayed in the network management topology diagram; the topological connection within a node refers to the fiber connection between two adjacent nodes. The optical fiber connection between two single disks is not displayed in the network management topology diagram.

[0122] Furthermore, in actual operation, it is first necessary to analyze the nodes in the communication network, as well as the fiber connections within and between nodes, and complete the creation of the optical layer node data set and the topological connection data set.

[0123] Further, the optical layer signal processing unit disk in step B refers to the line service disk, the branch line integration disk, the combination and separation disk, the optical cross disk, the optical protection disk, and the optical amplifier disk; wherein, the c...

The optical-layer service layering model configuration method comprises the following steps: collecting three types of nodes including WDM (Wavelength Division Multiplexing), an OTN (Open Transport Network) anda POTN (Packet Optical Transport Network) in a communication network in a communication network, and topological connection between the nodes and in the nodes; collecting an optical port in each nodeon an optical-layer signal processing unit disc, and generating logic point objects of three levels including an optical transmission section OTS, an optical multiplexing section OMS and an optical channel OCH under the optical port; analyzing the logic point objects under the optical port and generating single-disc internal crossed connection of two levels including the OMS and the OCH; establishing end-to-end sub-network connection of the three levels including the OTS, the OMS and the OCH in network elements layer by layer; crossly configuring a downloading optical layer to equipment underthe established sub-network connection, so that the complexity of processing service data by an upper layer is simplified and the user experience is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method and system for configuring a layered model of an optical layer service in a network management system. Background technique [0002] With the rapid development of optical fiber communication technology, the early WDM (Wavelength Division Multiplexing) technology has changed the ultra-low utilization of only one wavelength channel in one optical fiber, making full use of the huge bandwidth resources of the optical fiber ( low-loss band), so that the transmission capacity of an optical fiber increases several times to dozens of times compared with single-wavelength transmission, thereby increasing the transmission capacity of the optical fiber and reducing costs, which has great application value and economic value. However, as application scenarios become more and more extensive and complex, OTN (Optical Transport Network, Optical Transport Network) as the ...
