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 is a simulation apparatus for verifying a hybrid system. The simulation apparatus includes a system model input unit, a model information storage unit, a simulation unit, and a result display unit. The system model input unit receives subsystem models which model subsystems included in a hybrid system. The model information storage unit stores the subsystem models and information about the operations of the subsystem models. The simulation unit runs a simulation of the subsystem models based on the information about the operations of the subsystem models stored in the model information storage unit. The result display unit displays the results of running the simulation of the subsystem models using the simulation unit.
