Traffic Prioritization
The router may give preference to bandwidth to:
- VoIP calls (no echo or delay)
- IPTV (guaranteeing the absence of a buffer when playing video).
- Online gaming (latency and jitter minimization).
- HD & 4K streaming
This is particularly noticeable when the household has multiple users, and bandwidth competition can cause buffering and lag.
Assisted Scheduling Algorithms.
- SP (Strict Priority)
Prioritizes high-priority traffic.
- WRR (Weighted Round Robin)
Hands out bandwidth equally to various classes of traffic.
- SP+WRR Hybrid Scheduling
Balanced distribution and high-priority responsiveness.
Operator-Level Customization
ISPs can customize quality of service policies to correspond to:
- Local network conditions
