LAN interconnections have considerably in- creased since the end of 80's. In most cases, the ser- vice is implemented by service providers, which has accelerated the growth of data networks. As a result of the growth, network management programs have become essential to service providers. Quite often the monitoring capabilities of these pro- grams have been found out to be insufficient. This fact has led to the need of development of more powerful tools. The primary goal of this research has been to de- sign a program that produces SNMP based quality factors which reflect the state of network devices.
