Explanation
Traditional data traffic (web browsing, file transfers, email) is both drop-tolerant and delay-insensitive because TCP provides reliable delivery through acknowledgments and retransmissions - if a packet is dropped, TCP will detect it and retransmit, so the end result is still correct. Slight delays are also acceptable since users are not experiencing real-time interaction. In contrast, voice is both drop-intolerant and delay-sensitive (latency above ~150ms degrades call quality), and video is similarly delay-sensitive and drop-sensitive due to its reliance on reference frames. This fundamental distinction drives QoS design: data is typically placed in best-effort or lower-priority queues, while voice and video require priority queuing.
