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 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: 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.
