1. A multicast method comprising:
- searching, by a multicast apparatus, one or more communication objects in a distributed network environment;
receiving multicast data from a sender-side communication object among the one or more communication objects;
receiving a polling message from the communication object that transmitted the multicast data;
sending a response message corresponding to the polling message; and
determining whether a transmission error has occurred between communication objects based on results of sending of the response message, and performing multicasting based on results of determination.

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.

6. A multicast apparatus comprising:
-
a search unit configured to search one or more communication objects in a distributed network environment, and to form a multicast group based on results of search; and a feedback error control unit configured to receive multicast data and a polling message from a sender-side communication object among the one or more communication objects, to determine whether a transmission error has occurred between communication objects, based on results of sending of a response message corresponding to the received polling message, and to perform multicasting based on results of determination. - View Dependent Claims (7, 8)
