摘要:
Provided are a system and method for hierarchical message transmission between devices in a network environment including heterogeneous networks. The system is for hierarchical message transmission between devices in a heterogeneous network environment in which a plurality of sub-networks including at least one device and having different characteristics are configured in the form of a hierarchical tree with respect to a super-network. Aggregators for collecting and transferring device information on the devices to another network, the super-network, or the sub-networks are prepared in the super-network and sub-networks. Each of the devices includes an application service interface, a plurality of network adapters, a network manager, an address mapping and storage unit, and a message manager. Accordingly, devices can effectively communicate with each other, and in a network environment including heterogeneous networks, communication between the devices and management of the devices can be provided simply and comprehensively.

A bridge for heterogeneous QoS networks is provided. The bridge comprises an UPnP QoS processing unit, a bridge function unit and at least two of network drive drivers. The UPnP QoS processing unit collects connection information connected through the networks and QoS requirement information thereof through an UPnP QoS structure. The bridge function unit establishes and releases connection by allocating resources based on the collected connection information and QoS requirement information, and performs a bridging operation according to connection information of a received frame. At least two of network device drivers are physically connected to the networks.

A system for fault prediction in a home network includes: a context generator for generating context information based on status data collected in real time about components of the home network; a specification interpreter for generating knowledge rules for fault detection by using specifications of the components of the home network; a context analyzer for analyzing if the context information meet the knowledge rules to classify the context information into normal situation contexts and abnormal situation contexts; a context pattern learner for generating new knowledge rules based on the abnormal situation contexts and fault rules corresponding to the abnormal situation contexts; a knowledge rule database for storing and managing the knowledge rules and the new knowledge rules; and a fault predictor for analyzing a correlation between the knowledge rules or the new knowledge rules and the generated context information, thereby predicting faults to be generated.
摘要:
A semantic home network management system includes: a home network for collecting sensing information based on a state of a home network and analyzing the collected sensing information to configure semantic information; and a cloud inference apparatus for collecting and managing the semantic information provided from the home network through an internet protocol (IP) network, and applying an inference rule to the collected and managed semantic information to provide inference rule-applied semantic information to the home network. The inference rule is a rule that performs inference by recognizing at least one of a device state, a network state, a system state, and a service state.
摘要:
A ship-borne device managing method includes allocating IP address information to a device when a device configuration information request message is received from the device through a network in a ship system; performing an overlapping test of checking whether the allocated IP address information is currently used in the device; allocating service session information necessary for provision of an application service regarding the device in case where the overlapping test determines that the allocated IP address information is not currently used by the device; and generating a device configuration information response message based on the allocated IP address information and service session information and transmitting the device configuration information response message to the device. The device configuration information request message may include information regarding the device in the form of text or binary.

Disclosed are an apparatus and a method for integrated management of digitalized information and dynamic resources of a building, in order to integrate and manage digital information associated with a building and information on resources dynamically managed, such as various sensors and devices, networks, services, and the like in the building built up in a building designing or construction stage, resource objects are generated for each of the digitalized building information and dynamic resource information collected from one or more dynamic resources associated with the building, and a list thereof is maintained and managed, and an integrated map of a resource relationship object representing a relationship between the resource objects is generated, maintained, and managed on the basis of the list.
摘要:
A communication method based on user datagram protocol (UDP) in a transmitter includes: segmenting a message provided thereto into packets of a predetermined size; allocating a serial number to each of the segmented packets; storing the segmented packets in a packet buffer to transmit the packets to a receiver in order of the allocated serial numbers; and waiting for a control message indicating packet receipt completion from the receiver. The communication method based on UDP in a receiver includes: receiving packets segmented by a predetermined size in order of serial numbers from a transmitter; and when the received segmented packets are message packets and there is no missing packet, assembling the segmented packets in order of the serial numbers to complete a message.
摘要:
A smart home system based on a cloud computing includes: a home gateway connecting a home network device to an external network, the home network device being connected to a home network at each home. The system further includes and a cloud server, connected to the home gateway, for collecting contents information stored in the home network device and resource information of the home network information and performing a unified management of the contents information and the resource information at the each home.
摘要:
An apparatus for integrally managing a ship includes a device manager for integrally managing different types of local ship devices in the ship by using a standardized protocol message; a local device manager for managing local ship devices in a legacy environment on the basis of an independent local protocol; and an inter-working framework (IWF) for performing translation of a protocol for compatibility between the standardized protocol and the independent local protocol to manage the different types of local ship devices between the device manager and the local device manager. The device manager receives a remote control instruction for remotely maintaining and repairing the local ship device from a remote server connected through a wired/wireless communication network.
