Abstract [en]

The market of data communications services has experienced a rapid growth over the last years. Atthe same time, the need for effective and reliable facilities for management of data communicationsnetworks has grown. Several products for the management are available on the market. At UnisourceBusiness Networks Svenska AB, the growing market of interconnection of local area networks, hasresulted in many new customers and large networks which need to be managed. The local areanetwork interconnection is done with routers attached to a packet switched network (e.g. Frame Relayand X.25).

The customers' demand for high reliability of the data communications has actualised the need fornew applications for network management. The management applications used today at Unisource donot enable the operators to manage and monitor the packet switched network and the routers with thesame application. The applications used today display the customers' networks with a graphical userinterface, but the routers are displayed in one application and the packet switched networkinterconnections are presented in another application. The main objective with this degree-project isto find an application, which finds and displays all the routers and their interconnections. In thisdegree-project we examine five applications available on the market and as freeware products. Thefive examined applications are HP Open View Network Node Manager, Optivity, SNMPc, Fremont,and Interactive Map. The functions of the applications are examined with the purpose of identifyingone application, which presents the best view of the routers and their interconnections. The mostimportant functions studied in this report are automatic discovery and mapping of network topology.The user interface and analysis tools of the applications are also studied in the report.

We also document the possibilities to restrict the traffic and to enhance the security of the routers,from Cisco Systems and Wellfleet Communications.
