dc.description.abstractReliable broadcast protocols are important tools in distributed and fault-tolerant programming. They are useful for sharing information and for maintaining replicated data in a distributed system. However, a wide range of such protocols has been proposed. These protocols differ in their fault tolerance and delivery ordering characteristics. There is a tradeoff between the cost of a broadcast protocol and how much ordering it provides. It is, therefore, desirable to employ protocols that support only a low degree of ordering whenever possible. This dissertation presents techniques for deciding how strongly ordered a protocol is necessary to solve a given application problem. We show that there are two distinct classes of application problems: problems that can be solved with efficient, asynchronous protocols, and problems that require global ordering. We introduce the concept of a linearization function that maps partially ordered sets of events to totally ordered histories. We show how to construct an asynchronous implementation that solves a given problem if a linearization function for it can be found. We prove that in general the question of whether a problem has an asynchronous solution is undecidable. Hence there exists no general algorithm that would automatically construct a suitable linearization function for a given problem. Therefore, we consider an important subclass of problems that have certain commutativity properties. We present techniques for constructing asynchronous implementations for this class. These techniques are useful for constructing efficient asynchronous implementations for a broad range of practical problems.en_US
