It is part of the ITU-T Recommendation series M. TMN provides a framework for achieving interconnectivity and communication across heterogeneous operations system and telecommunication networks. Network management and administration pdf standard interface allows elements from different manufacturers to be incorporated into a network under a single management control.
Mediation devices when it uses Q3 interface. It is not as commonly used for purely packet-switched data networks. These manage modern telecom networks and provide the data that is needed in the day-to-day running of a telecom network. OSS software is also responsible for issuing commands to the network infrastructure to activate new service offerings, commence services for new customers, and detect and correct network faults.
Includes the functions related to business aspects, analyzes trends and quality issues, for example, or to provide a basis for billing and other financial reports. Handles services in the network: definition, administration and charging of services. Distributes network resources, performs tasks of: configuration, control and supervision of the network. A network element provides agent services, mapping the physical aspects of the equipment into the TMN framework. Boca Raton, Florida: CRC Press. This page was last edited on 26 June 2017, at 13:07. Three significant versions of SNMP have been developed and deployed.
SNMPv1 is the original version of the protocol. More recent versions, SNMPv2c and SNMPv3, feature improvements in performance, flexibility and security. Managed devices exchange node-specific information with the NMSs. An agent has local knowledge of management information and translates that information to or from an SNMP-specific form.
NMSs provide the bulk of the processing and memory resources required for network management. One or more NMSs may exist on any managed network. SNMP agents expose management data on the managed systems as variables. The protocol also permits active management tasks, such as configuration changes, through remote modification of these variables. The variables accessible via SNMP are organized in hierarchies.
