UPnP uses UDP because of its lower overhead.

UDP does not need to confirm the received data and retransmit damaged packets.

UPnP uses UDP port 1900, and all usedTCPports come from SSDP activity and response messages.

This is done through a protocol called Simple Object Access Protocol (SOAP), which delivers XML messages.

Event Notification

GENA (General Event Notification Architecture) is an architecture for event notification in UPnP.

The service uses it to respond to service calls.

Each machine has a set of Model variables.

When they change, the control point will be notified.
