Upnp Middleware Technologies In Digital Home Networking In Applied Research

With the popularization of the computer and the development of the communication, home is never an isolated island of the information in the 21st century. The development of the digit technology and the unceasing appearance of the information appliances also accelerate the unceasing development of the digital home network technology. The digital home network technology make Internet penetrated into home network. And it makes possible that people can exchange visits all of the available information resource of Internet when he uses the computer at home, such as, shopping on the net, balance in hand, medical treatment and health care, entertainment, communication, tele-edcation and so on. People can also manage and control all of the information resource of the digital home network. The digital home network technology improves the quality of people's lifes, guarantees safety of the home, and makes peoples'life more convenient and funner.The key technology of the digital home network realization is the digital home network middleware technology. It successfully resolves the problems of connection, communication and cooperation between information appliances and service. And it realizes simple connection and simple control among information appliances. This paper emphasizes on studying two kinds of the popular digital home network middleware technologies, that is, UPnP and Jini technologies. Integrating the different service discovery of these two technologies, we present an UPnP and Jini interoperability framework. And it realizes these two technologies use the information resource and service each other only in one digital home network.In addition, the digital home network is also a kind of the brainpower network which need the guarantee of QoS. The digital home network uses a lot of kinds of the construct network technologies, and a lot of the sharing and transferring media files. For these different operations, the request of QoS is also different. There is an important task about how to guarantee the QoS of every operation in such network environment. For studying QoS of the digital home network, the paper emphasizes on studying UPnP QoS protocol farther. Integrating network configuration and service...
