Design And Realization Of Local Telecommunications’DSLAM Integrated Net Administrative System

Broadband dial-up connection has become the most common Internet connection method for end users, and thus the equipment of Rate Adaptive DSL Access Multiplexers (DSLAM) also has become one of the most widely used net equipment. With DSLAM’s features such as huge variety of equipment types, strong capacity of multiple upload methods and huge number of existing equipment quantity, the studies of DSLAM for integrated monitoring, maintenance and management have turned out to be a major concern of net administrators.This system is an integrated net administrative system which designed after careful discussion and communications with local DSLAM administrators with reference to the existing local telecommunication conditions and analysis of administrative needs. The system emphasizes integrated approaches of management, monitoring and analysis of the DSLAM equipment and it has increased the efficiency of net administrative maintenance, reduced the redundant and trivial works of maintenance staff. It will also be of great importance to the understanding and control of all DSLAM equipments and the prevention of machinery malfunctions.This thesis examines the design and realization of the integrated DSLAM net administrative system. The summary of each part is given below:First chapter begins with some concepts and background knowledge, then illustrates local telecommunication DSLAM net conditions in detail. It also proposes the necessity, aims and meanings of such a research.Second chapter is an introduction of the DSLAM integrated net administrative system with specific accounting of the system design ideology, principles and system functional modules.Chapter3mainly examines the module of DSLAM node information management. Because of DSLAM’s features such as huge variety of equipment types, strong capacity of multiple upload methods and huge number of existing equipment quantity, exact and detailed nodes’information BRAS become the most important demand. This chapter first designs the data table structure of this module and then describes the detailed designing approach and the web realizations for node information inquiries, modifications and input.Chapter4mainly studies the module of DSLAM node flux monitoring and threshold warning functions. With the development of Internet application and incresing demand of bandwith, the prediction of DSLAM node flux has turned more diffcult,. node stream monitoring and threshold warning functions become necessary This chapter mainly describes the realization method of adding DSLAM node stream monitoring, process monitoring and threshold warning. It also gives a statistical analysis of stream collection and introduced the realization of these functions on web.Chapter5examined the DSLAM node topology and warning function. Topology and warning function is one of the basic function for administration of network. It can give net administrators an uniform approaches of monitoring topology and collecting alert informations of all kinds of DSLAM equipments In this chapter, it first designs the necessary categorized data tables for node topology and warnings, then it describes the realization method of adding node topology, collection of warnings and refresh of monitoring node topology and warnings. Lastly, it introduces the web design of the topology and warnings.Chapter6summarizes the design of multiple statistical functions for net administrative uses and gives detailed explanations of realizations. Appropriate statistics will be of great importance to the understanding and control of all DSLAM equipments and the prevention of machinery malfunctions.Finally, the summary and conclusion for the whole system are presented.
