3.3.2 Timers
Each Network Test session has the following timers:
Per-QosInitializeSink Response timer: This timer is used to ensure response (or non-response) to a QosInitializeSink request. This timer is only valid while the controller attempts to establish a network test session with the sink.
Per-QosReset Response timer: This timer is used to ensure response (or non-response) to a QosReset request. This timer is only valid while the controller attempts to shut down a network test session.
Each entry in a Probegap Request Table has the following timer:
Per-QosProbe Response timer: This one-shot timer is used to ensure response (or non-response) to a QosProbe request where the Test Type field in the QosProbe header is set to 0x01 (that is, a probegap test). This timer MUST be tied to the originating QosProbe frame by means of the corresponding entry in the Probegap Request Table. In other words, as long as the sink has not responded to the QosProbe frame, the timer MUST remain active.
Each entry in a Timed-Probe Request Table has the following timer:
Per-QosQuery Response timer: This timer is used to ensure timely response (or non-response) to a QosQuery request. This timer MUST be tied to the originating QosQuery frame by means of the corresponding entry in the Timed-Probe Request Table. In other words, as long as the sink has not responded to the QosQuery frame, the timer MUST remain active.
