We have developed a residential gateway that centralizes device interfacing between the external Internet and internal devices as well as appliance networks. We have also proposed the concept of a service server to be implemented for a large scale of apartment complex or a wide area house. The primary components of the residential gateway to be implemented in this paper include a processor (Motorola MPC8240), persistent storage (flash RAM, extend storage device), networking modules (such as TCP/IP for Ethernet, ADSL), home networking (HomePNA, IEEE1394, PLC), device interfaces (serial or PCI), home automation, and telecommunication system (PSTN/SLT, VoIP, Video Communication), which are typically powered by a certain RTOS. Finally, we have test results validating the effectiveness of both the residential gateway and the service server.
