REMOTE ACCESS BETWEEN UPNP DEVICES

摘要

Universal Plug and Play (UPnP) technology may be used over the Internet or other wide area communications networks. In one illustrative example, a first UPnP-enabled device is to provide a UPnP service such as streaming media to various users over the Internet. The first UPnP-enabled device provides an on-line identity provider with user IDs of those users who are authorized to access the first UPnP-enabled device from a remote location. When a user wishes to receive the UPnP service from the first UPnP-enabled device, the user logs in to the on-line identity provider using his user ID and receives from the on-line provider an IP address associated with the first UPnP-enabled device. A user's application constructs a URL from the IP address and contacts the UPnP-enabled device at that URL. The user's application can then invoke the desired UPnP service.
