The Way Of Personalized Multimedia Service Provided And Research On Its Key Technology In Future Network

The current Internet architecture is based on TCP/IP protocol. The main purpose of its design is to solve the computer interconnection and the time division multiplexing problem of resources. This end-to-end design model assumes that the user and terminal is trusted and intelligent. The core part of Internet only make the best of providing forwarding service of packets, while establishing connection, the retransmission, congestion avoidance as well as intelligent safety part is placed in the terminal.With the increasingly rich of applications and computation models, the degree of community depending on the Internet gradually strengthened, flourished multimedia business caused by the increasing network traffic, and the personalized service demands of terminal user becoming more and more craving, TCP/IP system structure has been unable to meet the needs of the sustainable development of internet. The Internet architecture put forward higher requirements in scalable, dynamic and security controllability aspects.In order to fundamentally adapt to the future demand for sustainable development, it is necessary to change the Internet design, the construction. Services as the center of the Internet system structure has gradually become one of the hot research network. In this paper, several development trends of future Internet will be respectively conducted in-depth and the detailed contrast between them will be concluded, and we put forward to the user’s demand, the service as the center of the future Internet architecture: User-oriented, service-centric future internet architecture, and analysis the key technology of USFIA system, mainly for the expression of user’s requirement, service name and logo, service routing and forwarding mechanism.
