Q: What is UPNP? A: Universal Plug and Play (UPNP) is an architecture for common peer-to-peer networks for PC and smart devices (or instruments), especially in the home. Based on Internet standards and technologies such as TCP / IP, HTTP and XML, the UPNP allows such devices to automatically connect and co-work, making network (especially home networks) possible.
Q: What does UPnP mean for consumers? A: Simple, more choices and update experience. Network products containing universal plug-and-play technology are only actually connected to the network, you can start working properly. In fact, UPNP can be used in conjunction with any network media technology (wired or wireless). For example, this includes: Category 5 Ethernet cable, Wi-Fi or 802.11b wireless network, IEEE 1394 ("firewire", telephone line network, or power cord network. When these devices are interconnected with PC, users can make full use of various innovative services and applications.
Q: What is the technical factor of UPNP? A: The UPnP range is wide, because it is facing home networks, near networks and small businesses and commercial and residential buildings. Under the management of network control devices, it supports data communication between any two devices. Upnp does not depend on a specific operating system, programming language or physical media.
UPnP supports zero configuration network and automatic lookup feature, so that the device can be dynamically joined to the network, get the IP address, announce your name, provide functionality as needed, and understand the existence and function of other devices. DHCP and DNS servers are optional. As long as you are available on the network, you can use it. In addition, the device can also automatically depth from the network without legacy.
The UPnp draws the success of the Internet and inherits its components, including IP, TCP, UDP, HTTP, and XML. The UPNP involves collaboration between multiple suppliers to establish a standard device control protocol (DCP). Similar to the Internet, these protocols are based on the announcement line protocol, which is expressed as XML form and communicate via HTTP.
