ATM网中VPN业务管理的研究与实现

摘要

基于TMN的逻辑分层体系结构，提出VPN业务管理的体系结构，分析了体系结构中各个子系统的功能.在此基础上，提出VPN业务管理所需的管理信息模型及其与ATM网络层/网元层的管理对象的映射关系，并详细讨论了系统中的安全管理功能.%The VPN service management architecture is proposed based on the logical layer architecture of the TMN and the function of the subsystem in the architecture is analyzedBased on this,the management information model of the VPN service management is presented and the mapping relationship between this model and ATM networketwork element layer managed object classes is also given. The security function of the system is discussed in detail.
