IEEE1394-BASED ONE-WAY RING SYSTEM FOR AN INDOOR BACKBONE NETWORK, PARTICULARLY CORRELATED TO CONFIGURING AN INDEPENDENT SERVICE AND EVENT HOME NETWORK

摘要

PURPOSE: An IEEE1394-based one-way ring system for an indoor backbone network is provided to configure an independent service and event home network, and to use a high-speed IEEE1394 interface when constructing an indoor backbone network, thereby easily interworking with next-generation multimedia home appliances. CONSTITUTION: An RG(Residential Gateway)(31) is used to connect with a high-capacity external network. An SG(Service Gateway)(32) performs a clock master function for synchronizing entire clocks in connection with the RG(31), a traffic management function of an indoor backbone network, and a physical state monitoring function of a transmission line of the indoor backbone network. Plural SPs(Service Platforms)(33-37) perform functions of extracting desired data from the indoor backbone network or loading data on the indoor backbone network. The SG(32) and the plural SPs(33-37) form a one-way ring structure.
