Design And Implementation Of Key Technology Of Multi - Terminal Windows System

Due to the development of computers, the new generation of computer is rich in resource. The mainstream configuration machines run faster and faster, performance is beginning to show serious excess state. General applications can disposed of in a short moment, and a lot of system resources will be in a state of the waste, and the resource share is very low, especially Hyper-Threading P4 architecture, the utilization rate less than 10%. Personal version of Windows operating system although suport multi-user features, but at the same time, only one terminal can use the system software and hardware resources.To solve the above problem, Multiple Terminal Windows system was invented. This system modification internal subsystem starting mechanism of Windows operating system, the terminal can direct use the host resources via dedicated connection, each terminal can be the same as a real computer, while running a variety of applications in the host and share the host resources.Multiple Terminal Windows system mainly include multi-user login part, the device assigned part and the Multiple screen display part. This paper describes the design and implementation issues of the part of multi-user login and the device assigned. First, the study discusses the theoretical foundation of multi-user system, including the knowledge of Windows NT kernel, Windows Terminal Services, LPC Services, HOOK API and the PE structure.Next, we describe the principles and design process of the part of multi-user login and the device assigned part. The former include the Design and Implementation of the system session manager and the Win32 subsystem. The part of equipment distribution including the development of the theory and design processes of equipment distribution. The system development based on the C/C++language.The test results showed that after the use of Multiple Terminal Windows system, each host can have multiple user login at the same time, each user’s workstation as a separate computer, it can make a full use of computer resources, dramatically reducing the purchase and maintenance costs to achieve the goal of pre-designed.
