Sure, I can provide a detailed explanation of the two network problems that indicate a need to implement Quality of Service (QoS) in a campus network.
Excess Jitter: Jitter refers to the variation in delay of the arrival of packets. When packets arrive at different times due to variable delays, it causes jitter. Excess jitter is a problem that affects real-time applications such as Voice over IP (VoIP) and video streaming. When packets arrive out of order, the application experiences audio or video distortion or dropped frames, which can degrade the user experience. QoS can prioritize these real-time applications over other traffic to ensure that they receive the necessary bandwidth and latency to function optimally.
Bandwidth-Related Packet Loss: Packet loss occurs when packets are dropped due to congestion, buffer overflow, or errors in the transmission medium. Bandwidth-related packet loss occurs when the network is congested, and the available bandwidth is not sufficient to handle the traffic volume. This can result in degraded performance and slow network speeds. QoS can be used to ensure that critical traffic such as VoIP or video streaming is given priority over less important traffic, which can help to reduce packet loss and improve network performance.
Therefore, options B (excess jitter) and E (bandwidth-related packet loss) are the two network problems that indicate a need to implement QoS in a campus network.
