Abstract

We consider three kinds of ordering properties provided by a multicast system. The messages can be delivered to the different recipients according to a local order, a causal order or a total order. In this paper, a formal method is proposed to prove the total and causal order of multicast protocols. A generalized formal result for multicast protocols is obtained. Some addressing features for other formal results are considered. This study allows to prove that existing systems have the required property. The results can be used to define new solutions. Moreover, the method makes use of various ordering properties, well fitted to practical systems, to achieve a better understanding of the ordering processing.
