3.1.2 Timers

The client peer MUST set a request timer when sending a Probe message to wait for a certain period of time for the incoming replies. The request timer is configurable such that system administrators can adjust the value based on their current network environments. The default value of the request timer is in the range of 200 milliseconds to 500 milliseconds, and under all circumstances, the waiting period SHOULD NOT be smaller than the maximum backoff timer value as defined in section 3.2.2 to ensure that enough replies are received by a requesting peer. When the request timer expires on a requesting peer without receiving any ProbeMatch replies, the implementation MUST remove that Probe message and its associated HoHoDk List from the Outstanding Probe List.
