Abstract :
Replication handled by software on off-the-shelf hardware costs less than using specialized hardware. Although an intuitive concept, replication requires sophisticated techniques for successful implementation. Group communication provides an adequate framework. We present a survey of the techniques developed since the mid-1980s to implement replicated services, emphasizing the relationship between replication techniques and group communication
