摘　　要：随着网络技术的迅速发展 ,网络管理的重要性在网络建设中变得越来越突出 ,网络管理协议 SNMP也从版本1.0发展到了版本 3.0 .但到目前为止 ,SNMP协议还主要是一种请求 /应答式协议 ,由于 SNMP协议的这个特性 ,当它被用在大规模网络管理时 ,就会造成带宽浪费和管理实时性的缺乏 .本文针对这个问题 ,提出一种基于 Push技术的解决方案 .该方案包括两部分 :Push协议操作的设计和 Push- MIB的设计 ,Push协议操作定义了 Push- PDU,它用于 Push数据的封装 ;Push- MIB用于 Push操作的相关参数的定义 .本文提出的 Push技术是对传统网络管理协议 SNMP协议的很好的扩充 。The importance of Network Management has received more and more attention with the rapid development of networks. SNMP, evolving from version 1.0 to version 3.0 in a few years, is a request/reply based protocol. For this reason, SNMP will consume large bandwidth when transmitting management information in large scale network management. Also, it is difficult to associate precise real time with the data set delivered due to the network latency. In order to solve the problems, this paper presents a solution based on push technique which is composed two parts: the design of the push protocol operation and the design of Push MIB. The push protocol operation defines the Push PDU which is used to encapsulate the data being pushed. The Push MIB is used to define the parameters of the push operation. The solution presented in this paper is an extension of SNMP and can achieve better performance in practice.
