Abstract: Disclosed herein are a multicast apparatus and method. In the multicast method, a multicast apparatus searches one or more communication objects in a distributed network environment. Multicast data is received from a sender-side communication object among the one or more communication objects. A polling message is received from the communication object that transmitted the multicast data. A response message corresponding to the polling message is sent. It is determined whether a transmission error has occurred between communication objects based on results of sending of the response message, and multicasting is performed based on results of determination.

Abstract: Disclosed herein are an apparatus and method for generating a Quality of Service (QoS) profile. The apparatus includes a user interface unit, a resource QoS policy generation unit, a traffic QoS policy generation unit, and a QoS profile generation unit. The user interface unit receives a QoS policy for Data Distribution Service (DDS) from a user. The resource QoS policy generation unit collects resource data for a device that performs the DDS, and generates a QoS policy for handling resources using the collected resource data. The traffic QoS policy generation unit collects traffic data for a network via which the DDS is performed, and generates a QoS policy for handling traffic using the collected traffic data. The QoS profile generation unit generates a QoS profile based on the QoS policy received from the user, the QoS policy for handling resources, and the QoS policy for handling traffic.

Abstract: Disclosed herein are an apparatus and method for discovering a communication entity. The apparatus for discovering a communication entity includes a list generation unit for generating a list of connection target Data Readers (DRs), a counter generation unit for generating a counter including information about a number of the connection target DRs, and a discovery message communication unit for establishing communication connections to the connection target DRs based on the list and the counter. The discovery message communication unit includes a transmission unit for transmitting a DR discovery message including data topic information or possible service quality information to each of the connection target DRs, and a reception unit for receiving a Data Writer (DW) discovery message including data topic information or possible service quality information from each of the connection target DRs.

Abstract: The present invention relates to an apparatus and method for sharing a topic between autonomic computing devices. The apparatus includes a knowledge base unit for storing information about abnormal states of an autonomic computing device. An autonomic computing management unit recognizes an abnormal state of the autonomic computing device based on the information about the abnormal states stored in the knowledge base unit, learns self-management for solving the abnormal state, and, when information about a new abnormal state is acquired during learning of self-management, generates a topic from the information about the new abnormal state. A topic transmission/reception unit transmits the topic generated by the autonomic computing management unit to a plurality of autonomic computing devices present in an identical domain or receives topics transmitted from the plurality of autonomic computing devices.
