There has no standard node for hfc access network , then we must extend the current mib tree if we want to manage devices by snmp , such as optic transmitter - receiver , edfa and so on 由于hfc接入网还没有定义标准的节点，因此，要用snmp对如光端机、光放大器等设备进行管理，必须要扩展原有的mib 。
The main work and innovation points of this dissertation include : 1 . a tmn - mib translator , i . e . , a method of translating the mib structures into c + + codes is designed and implemented 主要工作和创新是：设计并实现了tmn - mib转换器，即asn . 1 + gdmo描述的文本mib转换为用具体编程语言实现的mib 。
In our task , we will combine rough set theory and network fault diagnosis . we can apply rough set algorithm in mib data to find the relationship between mib and network faults 本文把粗集理论与网络故障诊断结合在一起，把粗集理论的算法应用到mib变量中，以挖掘出mib变量和网络故障之间的潜在关系。
The task of this artical includes below : ( 1 ) design the system general framework , analyze managed objects in mibs we need , design table structure which store these managed objects 研究内容主要包括以下几个方面: ( 1 )设计系统总体框架,分析mib库中所需管理对象集,并设计存储管理对象的数据库表结构。
The agent software introduced in this article is compatible for various snmp versions . using component models , the agent can extend the mib modules and meet the requirement of new implements 代理软件采取模块化的结构，适应多版本协议的要求，可以根据需要扩展所支持的管理信息库模块，实现新的应用。
User must post mib files to them , then they compile and send back well . such mode restricted the flexibility of development . on the basis of the present state , the author analyzed snmp agent Agent + +并没有提供mib文件的编译工具程序，需用户把mib文件邮寄给他们，他们编译好后再寄回来，限制了开发的灵活性。
The translation mechanism of mib from snmp to tmn is proposed and implemented with c + + method , and as an example , a proxy that allows a tmn - based manager to manage an snmp - based agent via cmip is presented 提出了snmp - tmn委托代理系统中mib转换的机理及其转换的c + +实现。在此基础上，构造了cmip和snmp的委托代理系统。
To network management , higher request is brought forward to extensibility of network device , especially to agent , because these controllable modules may contain their corresponding standard or privately owned mib 由于这些可管理模块可能包含其相应的标准或私有的mib ，故对于网络管理，尤其是对代理的可扩展性提出了更高的要求。
The local network management system can monitor local components through rs - 232 serial interface , and other snmp network management system can manage device remotely through the mib provided by snmp agent 本地网管通过rs - 232串口通信实现对设备的本地管理；其他snmp网络管理站通过snmp代理提供的管理信息库( mib )实现对设备的远程管理。
At first , i study the main parts of snmp framework , they are smi , mib and snmp . snmp ' s version has been developed from l to 3 , and the studies of their appl ications have also deve1oped 论文首先阐述了简单网络管理协议框架的三个组成部分，管理信息结构、管理信息库和管理信息协议，并对简单网络管理协议的三个版本的内容作了比较。
