Peer Group-Based Dependency Management in Service-Oriented Peer-to-Peer Architectures

摘要

Dependency management in service-Oriented peer-to-Peer architectures aims at handling functional dependencies between a public service hosted by a service providing peer and all consumer peers that rely on that service. The analysis of dependencies on consumer peers is important for supporting the adaptation of a public service. The uncoordinated adaptation of public services potentially leads to malfunctions in the environment of depending peers. In this paper, a novel way for handling service dependencies in peer-to-peer architectures is proposed. This approach suggests that peers of a peer group agree on a common adaptation policy that prescribes how service providing peers have to deal with potential dependencies before an adaptation can be pursued.
