| Traffic | Characteristics | QoS requirements |
| Haptic
| Transmission rate of 1000 packet/sec | Delay 50 ms | Constant packet rate | Throughput 500 kbps–1 Mbps | Sensitive to jitter and delay | Jitter 2 ms | | Packet loss 10% |
| Voice | Alternating talk spurts | Delay
150 ms | | Throughput 22 kbps–200 kbps | Silence interval | Jitter 30 ms | Talk-spurts produce constant packet | Packet loss 1% |
| Video | Highly bursty traffic | Delay 400 ms | Long-range dependencies | Throughput 2.5 Mbps–5 Mbps | | Jitter 30 ms | | Packet loss 1% |
| Data | Poisson type | Zero or near-zero packet loss | Long-range dependencies | Delay may be important |
