An overview of operating system for next generation internet server (NGIS)

The Next Generation Internet Server (NGIS) is a system specialized in Internet-based cyber communities in Korea with the high-performance Internet-based communication infrastructure, high quality of wireless communication environment, and high degree of Internet usage. In this paper, we present architectures and design features of operating system for NGIS. The Operating System (OS) is composed of an OS kernel, commands, libraries, and system utilities. System utilities include performance tuning, system status monitor. We describe the overall structure of the OS subsystem, its major components, the roles of each component, and the relations among components. These include the enhancement of the network and system performance, the support of new hardware such as NS device, I/O driver (ioctl style) for a system monitoring, and utilities for a performance analysis environment.
