本文提出了一种新型的按责任划分的集成网络管理系统（INMS）的分层模型。利用这个模型，可以实现INMS 的系统管理功能与针对不同设备的具体管理功能的分离，从而可以支持“独立开发、集中管理”的系统集成方案。关键词 INMS，管理目标，分层模型Abstract A new duty-layered model for integrated network management system(INMS) whichwill lead to the separation of special management functions for different equipment from general management functions of INMS, and thus may directly support the “independent development and centralized management” system integration scheme, was introduced in this paper.Keywords：INMS，Managed Object，Layered Model
