Abstract: In network management, the Request-Reply(RR) model in Simple Network Management Protocol(SNMP) leads to the general disadvantages of overfull traffic, and sometimes-intolerable time lag. To overcome them, this paper proposes a Register-Distribute(RD) model, in which a concept of the object attributed table and its organizing style are given. To achieve it, the Management Information Base(MIB) is extended to constrain the behavior of every agent, and one distribution protocol is designed to support the novel RD model and resolve the compatibility between RR model and RD model. Experimental results show that the RD model decreases the traffic, and avoids the time lag effectively. Therefore, the proposed RD model can make the SNMP more efficient than the traditional RR model.

摘要： 针对网络管理时简单网络管理协议(SNMP)中请求/响应模型造成的管理信息流量大、存在时滞的缺陷，提出一个注册/分发(RD)模型，给出对象属性表的概念及其组织方式，对管理信息库进行扩充，阐述为支持RD模型而增加的分发协议，解决与RR模型的兼容性问题，降低管理信息的流量，有效避免了时滞问题，从而实现SNMP协议的高效操作。
