The platform can automatically generate snmp agent according to the managed object information models presented by users and offer application programming interfaces to users 該平臺可以根據(jù)用戶所提供的被管對象信息模型,自動生成snmp網(wǎng)管代理軟件,并為用戶提供應用編程接口。
Second , it do research on the theory of quality of service , such as intserv and diffserv module , qos protocols , qos array techniques and qos architecture . third , based on the current techniques as j2ee , wfe and xml , an architecture of a pbnm system using ejb and wfe is presented . forth , it is discussed for some key components in pbnm domain , such as qos information module , policy based metwork management framework and the relations among components fifth , it designed the relations and communication interface between pbnms and other oss modules , and elaborated a strategy of building a distributed object information model and discussed its specific implementation , and implement the policy hierarchy using domain 本文的主要研究工作和成果如下:分析了傳統(tǒng)的網(wǎng)絡管理技術和發(fā)展歷程,對網(wǎng)絡管理的國際標準cmip 、 tmn 、 snmp和cops等及網(wǎng)絡管理的功能進行了討論;對服務質(zhì)量( qualityofservice , qos )中的主要理論,如intserv和diffserv服務模型、 qos協(xié)議、 qos隊列技術、 qos體系結構進行了探討;基于當今的流行技術j2ee 、 wfe 、 xml ,提出并設計了以ejb wfe框架構筑的策略管理體系結構;討論了基于策略的網(wǎng)絡管理( pbnm )中的若干關鍵技術問題,如策略信息模型、策略網(wǎng)絡的系統(tǒng)構架及組件間的交互關系;設計了基于策略的網(wǎng)絡管理系統(tǒng)( policybasednetworkmanagementsystem , pbnms )與運營支撐系統(tǒng)( operationsupportsystem , oss )各模塊間的關系和通信接口,運用分布對象技術建立網(wǎng)管信息模型,運用域進行策略的等級管理;討論了策略服務器( pdp )和策略實施點( pep )的工作流程,采用關系數(shù)據(jù)庫進行策略的存儲,設計并實現(xiàn)了策略數(shù)據(jù)庫、策略服務器( pdp ) 。
