【摘要】 简单网络管理协议(SNMP)是最早提出的网络管理协议之一，它一推出就得到了广泛的应用和支持。目前SNMP已成为网络管理领域中事实上的工业标准。 当SNMP被广泛地用于管理Internet上的主机和网络设施时，许多重要的商业应用从主机向PC服务器、桌面和各种手持移动设备转移，为了促进这些非标准设备的管理，桌面管理工作组(DMTF)在1994年颁布了DMI1.1标准。1998年颁布可远程管理DMI设备的DMI2.0，2003年又颁布了DMI2.0.1。 DMI是由行业指导机构Desktop Management Task Force(DMTF)起草的开放性的技术标准，它从本质上讲是管理桌面系统的一种解决方案。如果一台机器预装了特定的低端软件代理(DMI服务层，组件界面，和管理界面)，就被认为是符合DMI2.0标准的。所有符合DMI2.0标准的软件包都能对机器进行查询，并生成包含机器中所有主要组件(例如处理器、内存和BIOS)的列表。 虽然SNMP在网络管理中应用非常广泛，已经成为了事实的标准，但是它在对桌面设备的管理却是鞭长莫及，而这正是DMI的特长所在，因此解决SNMP和DMI之间的互操作，实现对DMI设备的SNMP管理十分重要，这对于扩展SNMP可管理对象的范围，解决异质网管间的互操作，对不同协议的网络产品进行统一的SNMP管理，保护用户对现有网络设备的投资等都有重要的现实意义。 我们引入分布式代理的概念，提出了一种DMI-SNMP的转换代理模型，用于两大网络管理协议SNMP、DMI之间的互操作，并通过实现该模型的原型系统来对DMI组件设备进行SNMP管理。更多还原

【Abstract】 SNMP(Simple Network Management Protocol) was one of the early proposed protocols. It has been widely used and supported. Nowadays it is practical industrial standard.When SNMP was widely used in managing hosts and network equipments, many important business applications moved from hosts to PC servers, desktops and various hand-held mobile equipments. For promoting such offstandard equipment management, DMTF(Desktop Management Task Force) released DMI 1.1 in 1994, and released DMI 2.0 capable of remote DMI equipment management in 1998, and then released DMI 2.0.1.DMI is a open technology standard drafted by trade steering oganization DMTF. Intrinsically, it is a method to manage desktop system. A computer on which certain low side software proxies(DMI service layer, component interface, and management interface) are installed is considered accordant with DMI 2.0. All the software packets which are accordant with DMI 2.0 can query computer and then generate the list of main computer components(such as CPU, memory and BIOS).SNMP has been widely used in network management and has been practical standard, but it is too far away to be capable of desktop equipment management, which is strong point of DMI. Consequently, it is important to solve the problem of mutual operation between SNMP and DMI for enabling SNMP management of DMI equipments, which has important practical meaning in extending the range of objects could be managed by SNMP, in solving the problem of mutual operation between heterogeneous networks, in unified SNMP management of network products abide by different protocols, and in securing client’s investment on existed network equipment.We introduced the concept of distributed agent, and proposed a transfer proxy agent model of DMI-SNMP for mutual operation between two main network management protocols: SNMP and DMI. Furthermore, we enabled SNMP managementof DMI component equipments by implementing the prototype system of that model.更多还原
