Description:You were hired as a network engineer for a small firm that had just recently implemented a voice-over Internet protocol (VoIP) solution in its converged network, which had replaced all of its analog lines. During your first week on the job, you hear a lot of complaints about the quality of the voice calls, and you have also noticed this yourself on a few occasions. You started an investigation to identify and resolve the root cause. You noticed that both voice and regular data traffic are using the same virtual local area networks (VLANs), and there was no priority given to the traffic.You have heard of the term quality-of-service (QoS) and know that this could be implemented to prioritize traffic flow as it moves across the network. You do not have all of the details about how QoS works, but want to because you believe it could help. Using all available resources, complete research on QoS. In 4–6 pages, addressed the following:Describe quality-of-service.Describe why you believe it is important to have this technology configured in a network.Provide at least 1 example of how it could be beneficial.Describe a time that you have utilized quality-of-service in your job. If you have not utilized QoS, describe a situation where you believe it would have been beneficial. Be specific with details in your discussion.
