:OSI-SM/SNMP(开放系统互连 -系统管理 /简单网络管理协议 )在管理信息传输协议和管理信息库 (MIB)上存在着极大差异 ,但大型异构网络管理和端—端的网络管理要求它们能够实现互通和互操作 .本文研究实现它们互通的委托代理技术 ,将OSI-SMMIB映射为相应的SNMPMIB以实现综合网络管理 ,并介绍了MIB转换的C+ + 实现方法 : OSI-SM / SNMP (Open Systems Interconnection - Systems Management / Simple Network Management Protocol) There is a big difference between the Management Information Transfer Protocol and the Management Information Base (MIB), but large heterogeneous network management and end-to- Management requires them to achieve interoperability and interoperability.In this paper, we study the principal-agent technology to realize their intercommunication, map OSI-SMMIB to the corresponding SNMPMIB to realize the integrated network management, and introduce the C + + implementation method of MIB conversion
