Provided are a fault model and rule based fault management apparatus and method for a home network. The fault management apparatus includes: a plurality of fault generation unit formed in a multilevel structure and generating fault notification when a fault is generated; a plurality of fault communication unit for transferring fault notification from one of the fault generation unit; a fault agent unit for transferring each fault notification from a plurality of the fault communication unit; and a fault diagnosis and process unit for receiving the fault notification from the fault agent unit, diagnosing a corresponding fault, and processing the corresponding fault using a fault model, a fault decision rule, and a fault process rule.

Provided is a home network connection management system using UPnP (Universal Plug and Play) and VLAN (Virtual LAN) multicast. The home network connection management system includes a UPnP-VLAN interfacing section for receiving requests of registration of VLAN and multicast addresses from a UPnP device in response to connection establishment commands from a connection manager, a VLAN managing section for registering the VLAN and multicast addresses in a VLAN mapping table according to connection establishment request from the UPnP device through the UPnP-VLAN interfacing section, the VLAN mapping table for matching and storing the VLAN and multicast addresses under the control of the VLAN managing section, and an Ethernet device driver for retrieving the VLAN and multicast addresses from the VLAN mapping table in response to TCP/IP data from an outside, forming the received TCP/IP data into VLAN frames, and transmitting the VLAN frames.

The present invention relates to a method for generating a decision tree using an inference engine in a ubiquitous environment. In the method, a data table for a data event set is generated based on information collected by at least one sensor. Subsequently, a weight value of the data event set is established, and an entropy is calculated based on the established weight value (here, the entropy is a scale for classifying the information collected by the sensor into respective classes). In addition, the decision tree for the collected information is formed based on the calculated entropy.
