Managed Gigabit Switch

The duration, carried in SSDP packets, is used to inform a control point or control points how often it or
they should receive an 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.
