Explanation
Quality of Service (QoS) is the mechanism that prioritizes certain types of network traffic over others. VoIP (Voice over IP) and VTC (Video Teleconferencing) are real-time, latency-sensitive applications that degrade significantly with delay or jitter. QoS ensures these traffic types get forwarding priority over less time-sensitive traffic like file transfers or email. Fault tolerance addresses redundancy and uptime. Load balancing distributes traffic across multiple paths or servers. Caching engines store frequently accessed content locally. None of these address the real-time priority needs of voice and video like QoS does.
