Taxonomy of contention management in interconnected distributed systems

Interconnected distributed computing systems, such as computing Grids and federated Clouds, have been of special importance in both industry and academia. Resources provided in these environments are usually shared between users from different groups and/or organizations. Therefore these environments are prone to contention between user requests for accessing resources. Particularly, resource contention takes place when a user requests cannot be admitted or cannot sufficiently access resources because they are occupied by other requests. In this paper, we deal with different types of resource contentions occurring in interconnected distributed systems as well as approaches for resolving them. Approaches developed to resolve resource contentions share similarities in many aspects while being different in other aspects. We investigate the features of these approaches, identify and categorize the similarities and differences of them. Additionally, we review various resource management systems of interconnected distributed systems and group them based on the identified specifications.
