Experience with TCP/IP networking protocol S/W over embedded OS for network appliance

Currently, the market of multimedia information appliance based on Internet activated by the growth of both multimedia service and access of Internet augment the importance of TCP/IP protocol S/W which can provide the existing standalone embedded systems with Internet service. In this paper we analyze the architecture and function of TCP/IP module to depend on 4.4BSD OS (Operating System) runtime environment and propose the new method against TCP/IP module dependent on 4.4BSD OS runtime environment. And then we implement embedded OS for the network appliance that supports multitasking under its environment to use only physical memory in embedded system
