A TXOP is a transmission opportunity granted by the Access Point to the Station.

It is a given period of time during which the station can send as many frame as it wishes.

A service period is related to power saving. It's the period during which the Station listen before going back to sleep. It is initiated by the Station and allow the Access Point to send traffic destined to the Station that have been buffered.

In short :

TXOP , QoS mechanism, AP initiated, traffic from Station to AP

Service Period, Power saving mechanism, Station initiated, traffic from AP to Station
