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 method for gap analysis for topology inspection to recognize a topology of a deep segment through gap discovery in an Ethernet network, includes: a gap division process of dividing a gap into atomic gaps that are no longer divided through path crossing test (PCT); and a gap interpretation process of analyzing a final result of the PCT when the atomic gap is generated, to interpret a topology of the gap.
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.
摘要:
Provided are a system and method for managing location information for a home network. The system includes a device management means for collecting information of home network devices to form a device table, a location management means for generating a space data structure including a gridded home floor plan, and associating the device table with the space data structure on the basis of a location of the home network device, and a user interface module for receiving a location of the home network device to transfer the input location information to the location management means. Since location information of the home network devices is directly input, accurate location-based home network services can be provided.
