Which of the following statements is true regarding video traffic?
A.
Video traffic typically requires more bandwidth than voice traffic.
B.
Video traffic tends to flow in a consistent pattern.
C.
Video traffic is not susceptible to packet loss.
D.
Video traffic is not susceptible to packet delay.
Explanation:
Video traffic typically requires more bandwidth than voice traffic. Because video traffic must carry both audio
and video information, video packets are typically larger than voice packets, which have to carry only audio
information. As a result of the larger average packet size, more bandwidth is required to transmit video packets.
Video traffic is susceptible to packet loss. Packet loss occurs when sent packets do not reach the receiving
device. This can cause distortions in the video transmission and an overall loss of quality. Quality of Service
(QoS) is frequently used to reduce the effects of packet loss. QoS can be used to assign different priority levels
to different traffic types. When QoS is employed, traffic types that could be adversely affected by jitter, delay, or
packet loss can be given higher priority over other types of traffic that are less likely to be affected, such as
transactional data traffic.
Video traffic is susceptible to packet delay. Packet delay occurs when traffic is stalled due to reasons such as
network congestion. Packet delay can create unexpected pauses between the time a packet is sent and when it
is received. Packet delay can cause distortions in video transmissions, reducing the overall quality of the
communication.
Video traffic does not flow in a consistent pattern. Video images are often sent in bursts with short periods of
inactivity between bursts. QoS can be used to smooth bursty traffic by employing bandwidth management
