Description
Technical Field
The present invention relates to the field of transmission network technologies, and in particular, to a method and an apparatus for determining a physical same route.
Background
There are many logical structures of a transmission network, and from the security perspective, the ring structure will be mainly used, but the ring structure directly presents logical connections between network elements on an Element Management System (EMS), and the logical connections are finally carried on physical routes such as optical cables, pipelines, and the like on a physical layer. Communication faults caused by optical cable interruption are common faults in transmission services, the self-healing protection capability of a transmission network can effectively reduce the influence of the problems on the services, and the principle of the self-healing protection capability is that the influenced services are connected to a destination node through other paths. However, in the long-term daily maintenance process of the transmission network, after network connection and structure information are continuously adjusted, the situation that the main path and the protection path pass through the same optical cable is easy to occur; or even though different cables are passed, the two cables are laid in the same pipe section, namely, the same route. In this network structure state, once a natural disaster or artificial damage occurs, the service in the office cannot be protected by the self-healing protection capability of the transmission network, and the service is interrupted. Therefore, the transmission network maintenance personnel can periodically check the transmission network and judge whether the transmission circuit has the same route.
Because physical routes such as optical cables, pipelines and the like are not managed on the EMS, whether the corresponding logical structures have the same route risk on the physical routes such as the optical cables, the pipelines and the like can not be judged through the EMS.
The transmission circuit is an object for manual specific record maintenance, records a specific channel opened on a transmission network infrastructure, and detects whether a path passed end to end has the same route or not and whether the paths between different circuits have the same route or not. The transmission circuit is not equivalent to the direct service configuration on the network management equipment, the service configuration on the network management equipment does not record the specific use, and some service configurations are possible to be redundant contents.
Chinese patent publication No. 102377484a discloses "a method for detecting security of Optical cable service in/out station of transmission network station", which is to connect the fiber core, Optical cable and Optical cable physical carrying facilities (manhole, pipeline, pole, overhead, etc.) with static external line resources to the Optical Distribution Frame (ODF), terminal, transmission equipment and transmission equipment port in the station in a whole-course association manner, and detect the connection result and the transmission system in combination, thereby finding out the hidden danger of Optical cable security of the common carrying point (manhole, pipeline, pole, overhead, etc.) of the common cable of the access station which may cause total block of the batch service in the station. The defect of the scheme is that with the development of transmission equipment types and protection technologies, on Network management equipment, in various networks aiming at sub-Network connection protection of a Synchronous Digital Hierarchy (SDH) and Optical Transport Networks (OTN) and Packet Transport Networks (PTN), no transmission system setting exists, so that the transmission system cannot acquire through a factory Network management interface, and the technical scheme cannot be implemented under the condition. More importantly, because the transmission circuit is a specific channel opened on the infrastructure of the transmission network, and whether the same route exists or not indicates the security of the specific bearer service of the transmission circuit, for example, when a new base station enters the network, only part of service devices are involved, and only specific transmission circuits associated with the specific service devices are involved, the prior art cannot judge the same route problem for specific services, and cannot determine the risk of the same route in some specific services.

Determining the logic routing information of the transmission circuit comprises two methods:
the method comprises the following steps: the comprehensive network management system collects the information of network management equipment of network elements and nodes through which the transmission circuit passes, determines the type of the network management equipment, and judges the configuration mode on the network management equipment when the network management equipment is SDH equipment or OTN equipment; when the configuration mode is an end-to-end path configuration mode, acquiring an equipment path, respectively matching the transmission circuit with a starting port and an ending port of the equipment path, and when the configuration mode is matched with the starting port and the ending port of the equipment path, giving end-to-end logic routing information of the path to the transmission circuit as the logic routing information of the transmission circuit; when the configuration mode is a no-path mode, acquiring cross data of network elements through which the transmission circuit passes, and performing cross accounting on the configuration of ports on the transmission circuit to obtain logic routing information; when the network management equipment is PTN equipment, acquiring the pseudo wire information on the network management equipment, and matching the information of the transmission circuit with the pseudo wire information; and when the pseudo wires are matched, giving the end-to-end logic routing information finally inquired by the pseudo wires to the transmission circuit as the logic routing information of the transmission circuit.

At this time, the integrated network management system collects the cross data of each network element, and performs cross accounting on the port configuration on the transmission circuit to obtain a cross accounting result, which is the logical routing information of the transmission circuit.
And secondly, setting logic routing information of the transmission circuit.
