UPnP

This chapter introduces the Universal Plug and Play feature.

Universal Plug and Play overview

Universal Plug and Play (UPnP) is a distributed, open networking standard that
uses TCP/IP for simple peer-to-peer network connectivity between devices. A
UPnP device can dynamically join a network, obtain an IP address, convey its
capabilities, and learn about other devices on the network. In turn, a device can
leave a network smoothly and automatically when it is no longer in use.

How do I know if I am using UPnP?

UPnP hardware is identified as an icon in the Network Connections folder
(Windows XP). Each UPnP compatible device installed on your network appears
as a separate icon. By selecting the icon of a UPnP device, you can access the
information and properties of that device.

NAT Traversal

UPnP NAT traversal automates the process of allowing an application to operate
through NAT. UPnP network devices can automatically configure network
addressing, announce their presence in the network to other UPnP devices, and
enable exchange of simple product and service descriptions. With NAT traversal,
the device can do the following:
•
•
•
Dynamic port mapping
Learning public IP addresses
Assigning lease times to mappings
