UPnP Operations
 Addressing:
UPnPv1 devices MAY support IPv4, IPv6, or both. For IPv4, each devices should have DHCP
client, when the device gets connected to the network, it will discover DHCP server on network to get an IP
address. If not, then Auto-IP mechanism should be supported so that the device can give itself an IP
address.(169.254.0.0/16)
 Discovery: Whenever a device is added on the network, it will advertise it's service over the network.
Control point can also discover services provided by devices.
 Description: Control points can get more detailed service information from devices' description in XML
format. The description may include product name, model name, serial number, vendor ID, and
embedded services...etc.
 Control: Devices can be manipulated by control points through Control message.
 Eventing: Devices can send event message to notify control points if there is any update on services
provided.
 Presentation: Each device can provide their own control interface by URL link. So that users can go to
the device's presentation web page by the URL to control this device.
 2. Using UPnP in ZyXEL devices
In this example, we will introduce how to enable UPnP function in ZyXEL devices. Currently, Microsoft MSN
is the most popular application exploiting UPnP, so we take Microsoft MSN application as an example in this
support note. You can learn how MSN benefit from NAT traversal feature in UPnP in this application note.
