Generating Test Traffic
Many network performance tools generate their own network traffic to determine the current performance of the network. This technique requires math skills, as well as a knowledge of network theory. All network performance tools that analyze network performance by generating test traffic require two devices on the network. The network performance along the path between the two devices is determined by using the packet pair and packet train methods, described previously in the Bandwidth Capacity section. This is demonstrated in Figure 1.4. In Figure 1.4, the network performance tool determines the performance only between devices A and B. No other paths in the network are tested. In order to test other paths on the network, the testing devices must be relocated to other points in the network. Of course the alternative is to have multiple test device pairs and locate them at different points in the network. The trick is to place the smallest number of testing points that can cover the largest area on the network. As mentioned, calculating network performance requires you to send pairs and trains of packets across the network. The packet pairs do not take up much network bandwidth, but the packet trains can place a fair amount of data on the network. Care should be taken when using network performance tools that use packet trains, so as not to adversely affect production traffic on the network.

Geração de tráfego de teste
Muitas ferramentas de desempenho de rede gerar seu tráfego de rede própria para determinar o desempenho atual da rede. Esta técnica requer habilidades matemáticas, bem como um conhecimento da teoria de rede. Todas as ferramentas de desempenho de rede que analisam o desempenho da rede, gerando o tráfego de teste requer dois dispositivos na rede. O desempenho da rede ao longo do caminho entre os dois dispositivos é determinado usando o par de pacotes e métodos trem de pacotes, descrito anteriormente na secção capacidade de
