Abstract: A new modeling methodology of management information based on SID (shared information/data) is given with the analysis of SID model. NM3IS (novel modeling methodology of management information based on SID)partitions the data of network in three dimensions, divides the mode-ling process into three sub-processes:data abstract, model expression and relation mining. The methodology describes the information model for management from different granularity by the conception of dimension, domain, Top-class and sub-class. NM3IS can be used in different dedicated networks. It is technology neutral, and has the consistent format of information/data. It is proved by experiment and practice that NM3IS will be useful to guide the modeling of management information, share the information/data in different dedicated networks
, and implement the integrated network management system for multi-technology network.

Key words: network management, shared information/data, management information model
