Design And Implementation Of Fault Management In SDH Integrated Network Management

With the development of telecommunication and SDH(Synchronous Digital Hierarchy), the telecommunication network scale is more and more big, the network structure is more and more complicated,and the technical applied mode of information took place the very big variety,all these put forward the higher request to the application of the network. Faced with an increasingly large network and the equipments of SDH of different manufacturers, the level of network management is also the need to further enhance. Traditional network management which aimed at the concentrated type network management mode of the equipments of SDH of same manufacturers have already can't adapt the network development currently of need, network needs integrated network management which is a powerful, simple to operate and aims at the equipments of SDH of different manufacturers,through a network of workstations will be able to implement the interconnection of different manufacturers SDH various management and control in order to achieve integrated management of the entire network SDH.The thesis is according to the development of the high requirement and the new technology of the SDH Network Management, against network maintenance personnel to the most concern at the management, put forward a proposed comprehensive fault management models, namely, the independent of different manufacturers SDH Network Management integrated into a functional network, and the future unified producing integrated fault management, including network-wide fault analysis and fault location, fault work list management etc.As sub- system of SDH Network Management System simplify the system maintenance and hoist the system intelligence.Paper does research the key technique of the Fault management of SDH Network Management System: the architecture of NMS, the basic concept of SMN, many layers application structure of WEB technique. Based on this investigation,put forward the fault management system requirements, functional system architecture, system design framework; design the database, and some functional modules of system. At the end of the paper, the development orientation of this system is brought out.
