Quality of Service (QoS) is particularly useful if your business runs multiple services on the same network, especially when some are more important or time-sensitive than others. It helps prevent disruptions and ensures that key services (VoIP or video conferencing) run smoothly, even when the network is congested. If your business has plenty of bandwidth and doesn’t rely on these types of services, QoS might not be as necessary. However, for many companies, it’s a vital tool to keep communications and operations running effectively.
