SMDS PERFORMANCE MONITORING : TRAFFIC GENERATION, INFORMATION PROCESSING & ANALYSIS

Many aspects of the performance of data communication networks can be determined from the delay experienced by the packets and the number of packets lost and duplicated during communication. These characteristics are generally determined by monitoring the network links intrusively using dedicated monitoring equipment. The intrusively monitored data are usually not retrieved by the existing network management protocols (e.g. SNMP) and therefore do not form part of the basic Management Information Base (MIB). Thus the generation of test traffic, the management of measurement data and processing and analysis of performance information demand special consideration.

This paper describes an extensive network performance monitoring environment developed at Loughborough University. This includes the description of the monitoring apparatus, test methodology, database architecture, information structures, processing algorithms and analysis procedures.
