Introduction to TCP/UDP performance testing

Netrounds Test Agents include a powerful active traffic generator tool that can send TCP and UDP traffic to other Test Agents, enabling you to test and troubleshoot your network connections.

The receiving Netrounds Test Agents at the other end of the network link will calculate packet loss, jitter, and minimum/average/maximum delay, as well as determine if your network has the expected performance and quality for applications such as IP telephony, Citrix, or videoconferencing.

For TCP and UDP traffic generation, Netrounds supports both point-to-point and hub-and-spoke setups. In a hub-and-spoke setup, all selected Netrounds "clients" will exchange traffic with the Netrounds Test Agent selected as "server". For UDP, TCP and VoIP UDP, Netrounds also supports the full-mesh setup, where the system automatically generates connections between all selected Netrounds clients.

In this case, TCP and UDP traffic will be initiated by the clients, and traffic will be sent from the server to the clients using the same ports. This makes it possible to send traffic through a NAT device, as long as the Test Agent placed behind the NAT is selected as a client.

The performance metrics in tests affect fail/pass criteria, and in monitorings they are compared to the thresholds in the SLA.
