Partially ordering broadcast (PO) protocol

A design of a reliable broadcast communication system for unreliable broadcast networks like Ethernet and radio networks is presented. The authors try to provide a partially ordering broadcast (PO) service in which every entity receives all messages from one entity in the same order. The PO protocol does not require the total ordering of received protocol data units (PDUs). In order to provide a reliable broadcast communication among multiple entities on an unreliable broadcast service, a data transmission procedure, the execution of which is controlled by all entities in a distributed scheme, is proposed. The correctness of the protocol is shown. The protocol can be very useful in designing and implementing distributed systems, such as distributed database systems and distributed operating systems.<
