Communication control in computer supported cooperative work systems

This paper presents AlphaDeltaPhi-groups (ADP-group) as a communication tool for connection level management in distributed CSCW systems. In order to accurately model CSCW communication patterns, an ADP-group is a related set of cooperating processes whose communication is supported by allowing a spectrum of quality-of-service, message delivery reliability, atomicity and causal ordering options to co-exist within the same group. ADP-group communication provides appropriate connection management support and network control within distributed CSCW environments characterized by a heterogeneous mixture of equipment types, network performance and user activity levels. This efficiency is achieved by defining a small set of canonical group communication operations, by automatically making appropriate connections between data sources and sinks, and by using a receiver-based method of connection specification, monitoring and modification.
