8、t), but the basic concepts of TMN are in use. nFor instance, HP Openview (a popular network management product) is to a large extent realizing the TMN idea: unified, advanced network management system. HP Openview can use CMISE/CMIP, SNMP or other protocols to query network elements.英语反说，英语反说，汉语要正过来
