A method and system of providing reliable communication between member servers belonging to the same multicast group, the method including: maintaining a first server sequence corresponding to a first member server belonging to the multicast group and a stored server sequence corresponding to each of remaining member servers belonging to the same multicast group as the first member server, in a server sequence storage of the first member server; transmitting a multicast message including a first server identifier identifying the first member server and the first server sequence to the remaining member servers belonging to the multicast group; increasing the first server sequence maintained in the server sequence storage by a predetermined value whenever transmitting the multicast message; receiving a final sequence notification message from a second member server belonging to the same multicast group with the first member server, the final sequence notification message including a second server identifier of the second member server and a second server sequence corresponding to the second member server; identifying a second stored server sequence corresponding to the second server identifier, stored in the server sequence storage, based on the second server identifier included in the final sequence notification message; and requesting the second member server to retransmit a multicast message corresponding to a server sequence made by adding a predetermined value to the second stored server sequence when the second server sequence is not less than the server sequence made by adding the predetermined value to the second stored server sequence.
