QoS
QoS in 802.16e is supported by allocating each connection between the SS and the BS (called a service flow in 802.16 terminology) to a specific QoS class. In 802.16e, there are 5 QoS classes:
| Layanan | Singkatan | Definisi | Contoh Aplikasi |
|---|---|---|---|
| Unsolicited Grant Service | UGS | Real-time data streams comprising fixed-size data packets issued at periodic intervals | T1/E1 transport |
| Extended Real-time Polling Service | ertPS | Real-time service flows that generate variable-sized data packets on a periodic basis | VoIP |
| Real-time Polling Service | rtPS | Real-time data streams comprising variable-sized data packets that are issued at periodic intervals | MPEG Video |
| Non-real-time Polling Service | nrtPS | Delay-tolerant data streams comprising variable-sized data packets for which a minimum data rate is required | FTP with guaranteed minimum throughput |
| Best Effort | BE | Data streams for which no minimum service level is required and therefore may be handled on a space-available basis | HTTP |
The BS and the SS use a service flow with an appropriate QoS class (plus other parameters, such as bandwidth and delay) to ensure that application data receives QoS treatment appropriate to the application.
