Research And Implementation Of Condition Maintenance System Based On Network Management Performance Data In SDH Transmission Network

With the rapid development of SDH transmission network, people’s the dependence of network and demand of network performance is higher an higher, so the real-time overhaul of network is also more and more important. At present, the majority way of SDH network equipment maintenance is still traditional preventive maintenance and repair after troubles. But these maintenance methods bring a lot of inconvenience to network users.The development condition maintenance system in this paper can solve the the disadvantages of the traditional overhaul, and real-time monitoring of SDH equipment is to detect and solving problems, greatly improves the reliability of SDH transmission network.This paper deeply analyzed the SDH transmission network and introduces the key technology of condition maintenance system. And this paper detailed descrips the design and realization method of condition maintenance system in SDH transmission network.The system can real-time obtain network performance data through the TMF814interface. Then dispose these data and grade them according to certain rules and courts.According to scoring algorithm, this system can calculate the SDH transmission equipment’s score by using these score of the parameters.Finally, the maintenance system get the running state of the equipment is normal or not and give maintenance report timely through the analysis of SDH transmission equipment’s score. In addition, the user can view the points of SDH transmission equipment, maintenance report, curve of history score, the topology of the network and so on through the user interface of this system.The condition maintenance system through the CORBA’s production TAO and HOP to deal with data; In the server using the.net technology; Based on B/S model in the user interface with AJAX technology, and use EXTJS technology to display table.The test results show that the state overhaul results can judge the SDH equipment state, give overhaul suggestions, and to reduce the probability of failure. User interface is friendly and simple to operation.
