Research And Development Of The WBEM-based NMS

With the rapid development of computer network,more and more network devices and running services and included into the network,making it more complicated,thus bringing in more pressure to network management.Most traditional NMS(Network Management System) such as OpenView,IBM Tivoli,CA Unicenter focus more on device of network layer.And they are functionally powerful and easy to use,except for the high price,making them mainly used in large network management.Limited by the money and specific demands, LAN,Campus and WAN (campus-type network in short) management develops slowly and there is no mature NMS in this field.Based on the analysis of campus-type network management,this paper is supposed to put up with an architecture of NMS,and develop a Macis NMS to meet the requirement of campus-type network management.First,this paper will talk about the basic theory of network management and specify those models such as CMIP,SNMP,WBEM,CORBA etc.Also we will introduce most popular NMSes both from commercial companies and open source community.Second,we will stress more on the design and implementation of Macis NMS.Chapter 3 will put forward an architecture of NMS,covering most management demands in campus-type network,including system structure,technical structure and implementation.Chapter 4 talks about basic principles and core structure of Macis.And Chapter 5 mainly shows the setup of Macis and user interface.At last,the paper will analyze the weakness of Macis and propose modification suggestion.Macis is composed of three parts:data layer,network management layer and web interface layer.The core program is coded in C language and performs efficiently,mainly taking charge of the data input,process and output.External plugins written in perl or shell will perform the monitoring which improve the expansibility of the system.Based on B/S structure,Macis NMS is designed with good interface and utility,providing management of servers,services,hosts and other network...
