OTN circuit routing method and system

Abstract

The present invention discloses an OTN circuit routing method and a system. The method comprise the steps of converting the network element information of all original networks into network element codes in the binary system; comparing each field of the network element codes at the initial end of a to-be-established routing with each field of the network element codes at the terminal end of the to-be-established routing, judging whether the fields of the network element codes at the initial end and the terminal end of the to-be-established routing are the same or not, determining the hierarchy of the required routing according to different fields of the network element codes at the initial end and the terminal end of the to-be-established routing, and successively routing the backbone layer, the convergence layer and the access layer of a network from top to bottom; acquiring cluster nodes at the initial end and the terminal end according to the network element codes, and establishing the routing of each layer of the network based the cluster codes; and finally splicing up the already established routings of all layers of the network to form the complete routing. According to the technical scheme of the invention, the automatic routing and path-finding function of an OTN circuit in the cross-manufacturer, cross-region, cross-level and end-to-end manner can be realized. Meanwhile, the automation degree and the accuracy of the circuit debugging operation are improved. Moreover, the error rate and the configuration time of the routing operation through the manually searching and computing process can be reduced.

Description

technical field [0001] The present invention belongs to the field of OSS (Operation Support System, Operation Support System) transmission network of telecommunication, data communication and other SP (Service Provider, service provider), especially relates to a kind of OTN (Optical Transport Network, Optical Transport Network) circuit routing method and system. Background technique [0002] With the continuous development of optical transmission network technology, OTN network technology is becoming more and more mature. However, the hierarchical structure of the OTN network is becoming more and more complex, and the networks of different manufacturers are intertwined. At the same time, in terms of network operation, it is necessary to adapt to the centralized operation based on the end-to-end business and the automation and standardization of service provisioning to improve the overall operation efficiency of the transmission network. [0003] Currently, OTN networks are ...

Problems solved by technology

[0004] The provisioning of OTN network services still adopts the method of manual scheduling and configuration based on the network management of equipment manufacturers. The service provisioning period is long, the efficiency is low, and the rationality of service routing is not high.

[0005] OTN network elements are layered, managed by region, and by manufacturer. The codes of network elements are not uniform. It is difficult to quickly deploy various resource information on the network, and it is also difficult to quickly locate elements such as networks, systems, nodes, and ports. The efficiency of automatic search for service routes is not high.

[0006] The general route search algorithm is based on the continuous topology. For the discontinuous topology, the route cannot be searched out. However, there are physical jumps in the service routes of the OTN network, that is, the opening of the OTN service needs to consider the layout of the cables.
