Network monitoring with simple network management protocol in optical feeder network: Master's thesis

Riikka Lemminkäinen

Research output: ThesisMaster's thesis


This thesis has been written as a part of OAN (Optical Access Networking) project. The OAN project concentrates on developing an optical feeder network to connect different subscriber networks to the core network utilizing the Data over SONET (DoS) concept. In the growing networks, the need of automated network monitoring has been perceived. This thesis examines the monitoring of the OAN network using Simple Network Management Protocol (SNMP). A network monitoring system for the OAN network is planned and also partly implemented in the OAN test network. Furthermore, the feasibilities and limitations of the SNMP are discussed. An extendable share-ware network management tool, Net-SNMP, is used in the OAN project. Also, standardized Management Information Bases (MIBs) are utilized as much as possible by the planned network monitoring system. However, in addition to standardized MIBs, new OAN-specific MIBs are needed. Furthermore, the network management software needs to be extended to support the necessary MIBs. Extending of the Net-SNMP software to support an OAN node-card specific MIB is also described.
