UPnP FORUM

More information can be obtained from the Universal Plug and Play Forum web site. You must join the UPnP Forum, however, there is no membership fee.

UPnP device architecture, the focus of this article, is the definition of the UPnP structure. The UPnP Forum defines the protocols, certifies testing companies, and through working committees defines how similar devices will format and transmit data.

The data is defined using XML templates. UPnP Forum templates define domain-specific and device-specific meaning and the format of data on top of UPnP Device Architecture. UPnP vendors specify their own extensions on top of working committee work. Vendors can choose their own programming model on top of UPnP. UPnP is designed to be both language and operating system independent.

The UPnP Forum is an industry initiative designed to enable easy and robust connectivity among stand-alone devices and PCs from many different vendors. It is open to any company wanting to participate in driving the adoption of UPnP. Companies with interests in particular device classes should become UPnP Forum members and participate in the process to design schema templates for their device classes. Both Microsoft and Intel have provided UPnP SDKs for Windows and Linux, respectively, at no cost to the developer (see Table 1).
