Abstract: An event transport system using an RMT(Reliable Multicasts Transport) is provided to supply functions requested from a high-available system with only RTM by which multicast transport is enabled. An event transport management module(120) transports an event message transported from an application program through an RTM module(130). When transmission errors exceed the threshold value of the RMT module, the event transport management module transports a transport failure message to a mail box of a receiver. When an event transport system(100) restarts, the event transport management module requests the transport of an event list to the event transport system of the other nodes.
