Simple Service Discovery Protocol (SSDP) Element
The SSDP element is a system element to configure this functionality and cannot send or receive actions. It controls the UPnP discovery protocol that can be used to inform other participants on the network about the existence and embedded features of a device.
On Windows you can find these devices in your network view in the explorer.
A double click opens the default page of the device.
On every device a property dialog can be opened to see more details
If you like your device to show up with some hints about the configured functionality the configuration of this element can be used.
How UPNP works
Core of the implementation is to send out a short broadcast message that informs that a device is existing and how to get more information about it.
This allows to download a XML based device specification from the URL http://homeding/ssdp.xml *1
The [UPNP DeviceArchitecture Specification] contains all the details.
