Research On Broad-Band Based District Intelligent System

With the wide application of computer technology and rapid development of real estate, The requirement for intelligent house thus arises. In this paper a practical implementation of Intelligent District system is presented by analyzing the intelligent house's characteristics and current domestic and international situation of intelligent house development. In order to build an intelligent district, analysis of various technologies of broadband access network is firstly performed , and Ethernet is adopted as its solution. In the analyze of the home -network, main efforts are emphatically concentrated on specific communication implementations based on home gateway. Research on NAT are also carried out. the PM1S are also designed and analyzed, and a practical implementation of security system for intelligent district system by adopting several technologies such as firewall in this paper.
