Quality of Service is a strategy for managing jitter that allows you to prioritize certain types of traffic over others. By prioritizing critical applications, QoS ensures that these applications receive the bandwidth they need to perform optimally, thereby reducing the impact of jitter. For example, you might prioritize VoIP traffic over less time-sensitive traffic, such as email, to ensure that VoIP calls are not affected by jitter. Implementing QoS requires a thorough understanding of your network’s traffic patterns and the needs of your applications.
