基于臨時服務器的通信模式研究
[Abstract]:With the development of 3D Internet technology (Web3D) and distributed virtual environment (DVE), 3D virtual world is recognized by more and more people because of its stronger sense of reality and immersion, and better interaction. People participate in three-dimensional virtual world, free communication, cooperation, competition, entertainment and other activities. At present, the application of distributed virtual environment based on 3D technology is mainly reflected in the simulation of 3D games. Because there is a lot of information to be transmitted in 3D environment, the communication load of the system will rise sharply when more and more users are used, which may exceed the carrying capacity of the system and lead to the degradation of system performance. Therefore, it is of great significance to study the load optimization and scalability of servers in the distributed 3D virtual world. Firstly, this paper studies and analyzes the optimization methods of server communication load in distributed 3D virtual world, including the client-oriented network synchronization model and the dynamic DVE structure based on temporary server. Aiming at the problem that the poor client may not be able to complete the communication in the client-oriented network synchronization model, a client-oriented communication mode is proposed. Aiming at the problem of client migration at lower level when temporary server exits in dynamic DVE architecture based on temporary server, the communication mode based on temporary server is proposed, and the two communication modes are analyzed and compared. Secondly, the communication mode based on temporary server is analyzed, and its whole frame and flow are described in detail. This paper presents a design method of the temporary server load balance and the functions of the four components of UDP communication, and proposes an average standard configuration algorithm, which is based on the hardware resources and utilization rate of the client computer. Consider the possibility that the client will be selected as a temporary server. Finally, this paper designs an information transceiver system based on temporary server, and verifies the feasibility of communication mode based on temporary server.
