While response time behavior in computer technology is an important criterion for real-time applications, it plays an important role in real-time communication for interactions that must be executed in fractions of a second. It is largely determined by signal propagation times in the transmission media and the Internetworking components, such as switches and routers. Due to the frequently used store-and-forward method, buffering is required, which determines the dwell time in the network component.
An improvement in response time can be achieved by reducing the computation time and improving the latency. Latency is the amount of time that elapses between the sending of an action and the start of the response. In Internetcommunication, the term ping time is used.
