NEW QUESTION # 130
What statements are true regarding jitter and latency?(Choose all that apply.) Response:
- A. Latency is a measurement of the time delay experienced in the delivery of a frame.
- B. Jitter is a measurement of latency variability from one frame to another.
- C. Jitter is a measurement of the variance of the number of frames received from an application for a specific time interval.
- D. Latency is a measurement of the time required to transmit two subsequent frames.
- E. Jitter is a measurement of average latency based on a sample of >100 frames.
Answer: A,B
Explanation:
Jitter and latency are two important metrics for measuring the quality and performance of wireless networks, especially for real-time applications such as voice and video. Latency is the average time taken for a data packet to reach the destination, while network jitter is the irregularity in latency. When the latency is consistently high, it can mean a slow but stable connection. On the other hand, a high jitter means there may be sporadic disruptions or delays in the transmission, which can affect the quality of service and user experience. Jitter is caused by various factors, such as network congestion, interference, routing changes, hardware issues, or packet prioritization. Jitter can be measured by calculating the difference between the latency of two consecutive packets, or by using the standard deviation of the latency of a sample of packets.
Jitter can be reduced by using Quality of Service (QoS) mechanisms, such as traffic shaping, queuing, or scheduling, which can prioritize the packets based on their importance and sensitivity to delay. Jitter can also be mitigated by using jitter buffers, whichcan store the incoming packets and smooth out the variations in latency before delivering them to the application.
