| Abstract: | The performance of communications networks can be monitored intrusively by transmitting test packets on the network links being tested. The delays experienced by these test packets and the number of test packets lost or duplicated may provide an indication of the performance of the links being monitored. Intrusive network monitoring, even at modest sampling rates, generates a significantly large amount of primitive data. This data needs to be summarised appropriately to address the required network performance analysis operations. These operations are generally iterative in nature, where the results of initial processing and analysis generate requirements for further processing and analysis. This paper describes the architecture of a database that can assist in efficient analysis of network performance by reusing the information derived at various stages. |
