Method and apparatus for searching business route

Abstract

The invention discloses a business path searching method and a device, in order to aim at solving the problem that the business management cannot be carried out in a unified manner when an intelligent network element and an SDH network element combine a network in a mixed manner. The method comprises the following steps: a circuit in an intelligent domain is expressed as a cross corresponding to the circuit; all crosses on the network are obtained by acquiring all crosses in the common SDH network element and on the intelligent domain; a plurality of cross groups are obtained by classifying all the crosses according to the speed class, the speed of each cross in the same cross group is the same, and the plurality of cross groups are ordered according to the speed class from high to low; as to the ordered cross groups, the connection at the two ends of each cross is acquired and a business path corresponding to the speed class of the cross group is generated according to each cross andthe acquired connection. Therefore, the SDH business across the intelligent domain can be completely searched, the end-to-end management of the SDH business is realized, and the searching efficiency of the business path is improved.

Description

technical field [0001] The invention relates to the technical field of optical network communication, in particular to a method and device for searching a service path in an optical network. Background technique [0002] In an optical network, the system is composed of interrelated network elements. These network elements may be ordinary SDH network elements or intelligent SDH network elements. Users can perform various operations on a single network element, including creating services, setting attributes of network elements and boards, and so on. From the point of view of use, users want to be able to manage all services in the system. Therefore, service management requires end-to-end management. [0003] In the traditional SDH network service management, the SDH end-to-end path search of the network management needs to first calculate the cross-connection created by the service on a single station, and search for the end-to-end service through the cross-connection inform...

Problems solved by technology

[0010] On the other hand, since the intelligent circuit only manages intelligent services, if the intelligent network element does not use the control plane of the intelligent network element, that is, if it is used as an SDH network element and an intelligent network element at the same time, it needs to be managed separately in different subnets. Network elements, the data consistency of network elements in different subnets cannot be guaranteed
