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 translation: 这里公开了多播设备和方法。 在组播方法中，组播装置在分布式网络环境中搜索一个或多个通信对象。 从一个或多个通信对象中的发送方侧通信对象接收组播数据。 从发送组播数据的通信对象接收到轮询消息。 发送对应于轮询消息的响应消息。 基于响应消息的发送结果确定通信对象之间是否发生了传输错误，并且基于确定的结果执行多播。
