QoS mapping between IEEE 802.11e and IEEE 802.16e-2005 classes.

IEEE 802.16e-2005 parameter	IEEE 802.11e parameter	Description
Maximum Sustained Traffic Rate	Peak Data Rate	The peak information rate in bit per second
Maximum Latency	Delay Bound	The latency period starting at the arrival of a packet at the MAC till its successful transmission to the destination
Minimum reserved Traffic rate	Minimum Data Rate	The minimum data rate required by the traffic flow
Maximum Traffic Burst	Burst Size	The maximum continuous burst the system should accommodate for the traffic flow
SDU size	Nominal MSDU size	Number of bytes in a fixed size packet
Unsolicited Polling Interval	(a)	The maximum nominal interval between successive polling grant opportunities for the traffic flow
Unsolicited Grant Interval	(a)	The nominal interval between successive grant opportunities for the traffic flow
Traffic Priority	User Priority (b)	The priority among two IEEE 802.16e-2005 service flows identical in all QoS parameters.
Tolerated Jitter	(c)	The maximum delay variation (jitter) (in milliseconds)
