Implementation & Design Of Modeling & Simulating System Based On Network Computing Service

Where there is designing, there is system simulation. Since the middle of the 20^th century, great change has accrued with the impulse of Moore' s Law, as well as system simulation. With the development of network technology and system simulation, this paper bring forward a system simulation idea based on network computing environment, and an online simulation computing platform was developed according to the idea. Based on TCP/IP protocol, this platform uses web site as presentation layer, and professional system simulation software (MATLAB) as background server, which implements multi-user, multi-task, multi-thread simulation.System simulation began later in China than in other countries, but it has rose as a new force in recent years, and a lot of development has been made in national defense, industry and architecture. Since China formally connected to internet in 1994, internet has developed rapidly during such a short time. This fact can be reflected in not only our network infrastructure, but also in the number of users and in several industries. Since the break up of network foam in 2000, the development of network dropped to a low level. However, the network in China has come to a new age. The network application in China has aimed at multi-branches, globalization. New idea and techniques have spring out; new standard and new concept have been generated.With regard to combination of network computing and system simulation, though foreign companies like PTC have started to research, and there are already some products, the number of users is not large. There is still a lot of work to do in order to perfectly combine the two technologies. What the author did is just a small part, and it is hoped that better standards and specifications would be made in the future, and we will get a bright future in simulation and network computing.
