This book constitutes the refereed proceedings of the 13th IFIP/IEEE International Workshop on Distributed Systems: Operations and Management, DSOM 2002, held in Montreal, Canada, in October 2002.

The 16 revised full papers presented were carefully reviewed and selected from 40 submissions. The papers are organized in topical sections on managing quality of service, measuring quality of service, service architectures, policy and process, and fault analysis.

Communities are groupings of distributed objects that are capable of com- nicating, directly or indirectly, through the medium of a shared context. To support communities on a wide scale will require developments at all levels of computing, from low-level communication protocols supporting transparent - cess to mobile objects, through to distributed operating systems, through to high-level programming models allowing complex interaction between objects. This workshop brought together researchers interested in the technical issues of supporting communities. This workshop was the third in the...
