What is one effective way to improve network performance regarding latency and jitter?

Implementing quality of service (QoS) is an effective way to improve network performance, particularly concerning latency and jitter. QoS allows network administrators to prioritize certain types of traffic over others, ensuring that critical applications receive the necessary bandwidth and minimal delay. For instance, real-time applications such as VoIP or video conferencing require low latency and consistent delivery rates to function optimally. By adjusting the network's traffic management according to QoS configurations, less critical traffic can be deprioritized during peak usage times, thus maintaining the integrity and performance of more important communications.

This approach not only addresses the issues of latency (the time it takes for data to travel from one point to another) and jitter (the variability in packet arrival times) but also enhances overall user experience by ensuring that important data is delivered promptly, even in congested networks.

Other potential solutions might address aspects of network performance, but they don't specifically target latency and jitter as effectively as QoS. For instance, simply increasing bandwidth could help but may not mitigate issues such as packet loss or inconsistent delivery, which contribute to jitter. Similarly, implementing a firewall is crucial for security but does not inherently optimize traffic flow or reduce latency. Reducing the number of users may assist in decreasing congestion,
