Advertising Duration
The duration, carried in SSDP packets, is used to inform a control point
or control points how often it or they should receive a SSDP
advertisement message from this switch. If a control point does not
receive any message within the duration, it will think that the switch no
longer exists. Due to the unreliable nature of UDP, in the standard it is
recommended that such refreshing of advertisements to be done at
less than one-half of the advertising duration. In the implementation,
the switch sends SSDP messages periodically at the interval one-half of
the advertising duration minus 30 seconds. Valid values are in the
range 100 to 86400.
