A measurement-based performance evaluation method for IP networks and its implementation

In recent years, IP networks have become increasingly complex and the range of network applications has widened. As a result, the need for experimenta l evaluation of application performance has increased. We introduce a measu rement-based performance evaluation method that combines a function to gene rate various patterns of application traffic with one to measure end-to-end network performance at the application level. For our method, we also prop ose traffic models of various applications that can represent the character istics of these applications, for example, the burstiness of traffic. This method has already been implemented as a benchmarking tool on UNIX operatin g systems.
