Provided is a topology discovery method for an Ethernet network that can effectively discover a physical topology with respect to the Ethernet network of a mesh structure without developing and using a separate control protocol. The topology discovery method in an Ethernet network includes the steps of: acquiring an interface management information base (MIB) and a bridge MIB; defining and storing information for discovering a physical topology; discovering an edge bridge that divides a boundary between a bridge network and a host network; discovering the physical topology with respect to the bridge network by using the schema; discovering the connection relationship with the host network by using an address learning address forwarding table (AFT) with respect to the edge bridge included in the bridge network; and outputting the connection relationship of the bridge network and the host network as a graph.

Provided are an intelligent parking guidance apparatus and method. The intelligent parking guidance apparatus includes: an image sensor node recognizing a vehicle number of a vehicle, sensor nodes determining whether the vehicle exists in their own positions, a parking management server generating information for guiding the vehicle to an available parking space, and a mobile communication terminal receiving the information. The intelligent parking guidance apparatus and method provide information regarding parking lots which are within a predetermined distance from a destination and available parking spaces of each parking lot, to a driver, as well as provide a road guidance service to the driver to guide his/her vehicle to the destination, so that the driver can select an optimal parking lot. Also, when the vehicle enters the parking lot, the intelligent parking guidance apparatus and method guide the driver to an available empty parking space, thereby reducing difficulties in finding a parking space in a place which is unfamiliar to the driver.

摘要:
The present invention relates to a power-consumption control apparatus and method for a smart meter. The total amount of power consumption and amounts of power consumption of individual electrical devices connected are sensed, and the amounts of power consumption of the individual electrical devices are analyzed. The total amount of power consumption of the electrical devices is compared with a preset progressive amount on the basis of the analyzed result and supply and shutoff of power to the electrical devices is controlled on the comparison result. According to embodiments of the present invention, power consumption (power shutoff and supply) in homes, factories, and offices is automatically and effectively managed and controlled, which makes it possible for consumers to pay lower electrical bill and for power suppliers to improve the efficiency of power distribution by efficiently estimating power consumption.

Provided is a method for selecting only desired item information in a mobile terminal. The method includes the steps of: a) setting up an item category desired and selected by a user in the mobile terminal; b) reading item information stored in tags attached to items with a Radio Frequency Identification (RFID) reader loaded in the mobile terminal; and c) performing filtering and displaying only the item information of an item that belongs to the selected item category among the item information acquired by the RFID reader of the mobile terminal.
摘要:
The present invention provides a method of managing forwarding tables of network processors based on address learning in a line card. In this method, a demultiplexing module transmits N Ethernet data frames having the same source address to ports of network processors in sequence. Each of the network processors adds an entry to its address learning table and transmits the received Ethernet data frame to the main processor. The main processor determines whether an entry corresponding to the Ethernet data frame exists in its forwarding table. If the entry exists and the learning process count (LRNG_CNT) flag value is greater than zero, the main processor increases the LRNG_CNT flag value by one. If the entry does not exist, the main processor adds the entry to its forwarding table, increases the LRNG_CNT flag value, and requests creation of the entry in forwarding tables from the network processors.
