Abstract

This paper contributes a concise introduction to the field of group communication systems and is structured as three integrated parts. In the first instance, this paper aims to share the practical insight gained from the implementation of several group communication projects back into the community. This is discussed in a form that can be used to guide and steer subsequent projects. Secondly, the paper aims to benefit newcomers to the subject by offering an introduction to some of the more pertinent areas of the field through a snapshot of its current state. The subjects of failure detectors, group membership (including virtual synchrony variants) and security are discussed. Although this paper presents a general view on these subjects, it alludes to the exemplars of the Collaborative Computing Frameworks (CCF) and IceT where necessary.
