Which two solutions can be employed to mitigate jitter problems in a VoIP network?

In a VoIP (Voice over Internet Protocol) network, jitter refers to the variation in the time delay of received packets, which can disrupt the quality of voice calls. One of the effective methods for mitigating jitter is by implementing jitter buffers. These buffers temporarily store incoming packets before they are played back or processed, allowing for smoother delivery of the packet stream despite variations in arrival times. This is crucial for maintaining call quality, where timely delivery is essential.

In addition to utilizing jitter buffers, prioritizing network voice traffic is fundamental to ensuring that voice packets are processed and transmitted before other types of data. This prioritization helps to minimize delays that can worsen jitter, as it allocates more bandwidth and reduces competition for resources among different types of network traffic.

The other choices may address different network problems or improve overall performance, but they do not specifically target jitter issues as effectively as the combination of jitter buffers and traffic prioritization. Making sure that voice traffic is prioritized ensures that it gets through first, which is critical in a busy network environment. Thus, the choice of using devices that provide jitter buffers alongside prioritizing voice traffic directly addresses the factors contributing to jitter, making it the most suitable solution for mitigating these problems in a VoIP network.
