+RMCast is a reliable source-ordered multicast protocol implementation
+for message-oriented multi-sender group communication built on top of
+IPv4 multicast. It uses sequence numbers for re-ordering, duplicate
+suppression and loss detection. Negative acknowledgments (NAK) with
+retransmissions are used to recover from losses.
+
+One new and interesting idea implemented in this protocol is history
+transmission (dubbed negative retransmission). In a nutshell, each
+sender, along with normal payload, transmits a list of other sender's
+IDs along with sequence numbers of last messages received from those
+senders by this member. This, in some sense, builds a pyramid of
+information: each subsequent message carries some information for a
+number of previous messages (from other senders). This helps other
+receivers detect losses.
+
+The protocol does not track group membership. Messages are retained
+for retransmission for a predefined amount of time. The "last message
+or lost message" dilemma is solved by periodic history transmissions
+in cases when there is no useful traffic (idle network).
