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.

Disclosed are a remote maintenance and monitoring service framework for a heterogeneous device and a heterogeneous system. According to exemplary embodiments of the present invention, a common maintenance service framework for a heterogeneous device and a heterogeneous system is provided through a network, and as a result, a maintenance manager can perform remote maintenance without visiting the site, thereby saving time and cost. Further, remote maintenance management through a network can be provided without installing an exclusive line and giving a load to the local network. In addition, the heterogeneous device and system are commonly managed regardless of types of devices so as to remarkably reduce complexity of maintenance and management.

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.
