    Abstract

    In a packet network, the terms "bandwidth" or "throughput" characterizes the amount of data that the network can transfer per unit of time. This thesis deals with metrics, methods and tools used in measuring bandwidth. The goal is to build a tool that could be used for measuring bandwidth in accurate, reliable and relatively fast manner. First we take a look at a different and most frequently used metrics and then we present methods that can measure such a metrics. We also present tools that implement those methods and take a look at how some companies measure bandwidth. We describe the iperf tool in detail and explain the factors that have big effects in measuring TCP throughput. Iperf has been extended with SNMP functionality which is now used as a part of the BWMonitor, a tool used for measuring TCP throughput and bandwidth.
