Design And Implementation Of Unified Network Management Software Of Optical Receiver And EOC Based On SNMP

In an important national information infrastructure of radio and television network,with the years of the new direction of the development and convergence of Internet plus video and other strategic planning,continue to develop new business,put forward higher requirements on the quality of the network and the corresponding bearing capacity,upgrade of radio and television operators from traditional to two-way one-way video business digital interactive services,EOC Network Bidirectional Transformation Technology has become the mainstream,and carry out the business of video and data multiplexing coaxial cable network.In the radio and TV HFC network,communication device are also more and more such as optical transmitter,optical receiver,bureau of EOC end and terminal and early equipment does not have remote network management functions,with the escalation of the two-way network,have increased the management module,but there is a management is not mature,efficiency is not high.Because of radio and television network coverage,line extended to every household in the large network and complicated.To close to the user terminal equipment management and maintenance become radio and television operators are facing an important problem,such dispersed devices and many kinds of,various equipment manufacturers supply matching equipment management software are independent of each other is not uniform,and HFC network and PON + EOC network managed separately,even each network equipment management are independent and software update slow,which to network operation and maintenance personnel increased a lot of duplication,then a perfect function,simple operation of the unified network management platform is a good solution.Based on the demand of radio and television network company,this paper according to the actual management mode,in view of the network into people's homes before the optical node equipments,such as optical receiver and EOC equipment design development a topology management of the unified network equipment management system platform based on.System uses SNMP protocol development to achieve a unified set of MIB interface library network device management software,which can in the form of visual topological intuitive display,network management in large quantity,position disperse,difficult operation and maintenance optical receiver equipment and EOC local terminal and terminal equipment,reduce daily workload of operation and maintenance personnel,improve work efficiency.Experimental results verify the design management system can be a very good management of radio and television network PON + EOC network and HFC network optical receiver equipment and EOC,based on B / S architecture and topology graph implementation of equipment management,support for distributed deployment,multi user security policy division of the regional management,automatic scanning device discovery,remote configuration device,constantly monitoring equipment performance parameters,fault found alarm,regular data backup and statistical reports,and the output of.Software system in accordance with the national standard MIB unified interface package,has a very good compatibility and system modules have certain configurability and openness,network management in other equipment or docking integration to other systems,and tested in small batch equipment online operating environment,system is running stable,each functional module is working normally.
