“…Research to date has mostly focused on the policy conflict analysis within single network domains. In an attempt to extend this research topic to federations, Barron et al extended the DEN-ng policy model to support federation-wide policies [70]. More recently, they outlined a novel policy conflict analysis algorithm for federal management policies [71] based on this extended model.…”

SUMMARYThe Internet's original static services have been superseded by rich multimedia services with stringent end-to-end QoS requirements. Additionally, there has been a trend from simple applications offered by a single provider, towards service compositions, managed across the bounds of multiple domains. It is widely accepted that the end-to-end requirements of multimedia and composed services cannot be satisfied by the current Internet, which does not support inter-domain collaboration. The network federation paradigm was advanced to address these limitations. It envisions the automatic negotiation and management of dynamic agreements between network domains, allowing them to collaborate to achieve goals they cannot achieve alone. This article presents an overview of state of the art research in the area of federated network management. Specifically, existing definitions are compared and aligned. Moreover, the most important efforts towards an architecture for a federated Future Internet are discussed. Finally, we have identified several important research challenges that need to be tackled before the federated Future Internet vision can be fully achieved. For each of these challenges, existing research efforts are surveyed and remaining open issues identified.

“…The federation-level policy has been specified using the control policies. The model has been extended to include access process outlined in [3]. The policy contains context information control aspects and more specifically a limited set of XACML regarding the federation along with high-level federation rules Deployed XACML policies are assumed to map to higher level system policies.…”

“…This work will further demonstrate that when used in conjunction with each other they can provide policy specification and conflict analysis processes more powerful modelling of domains as this allows structural and semantic information relevant to each operating environment within each domain to be represented. This paper builds on our previous work [3] where the DEN ng federated domain model extension was used to assist in the specification of federation-level policies. Assuming that federation-level policies have been specified using the process outlined in [3], they will need to be checked for conflicts during the deployment phase.…”

This work describes how conflicts be tween newly deployed (or updated) federation-level policies and previously deployed local/federation policies can be detected.…”

We outline a policy conflict analysis process for the analysis of newly specified federation-level policies against previ ously deployed 10caVfederation policies. The process is generic in the sense that it can be employed by each domain participating in a federation to help maintain the consistency of their local system with that of the federation. The conflict analysis process utilises an information model and associated ontology for representing both the static and dynamic application-specific aspects of the local operating environment and the federation to aid in the detection of potential inconsistencies. It employs two algorithms, one for the selection of previously deployed policies related to the federation-level policy and the other for analysing the returned policies against the federation-level policy. The selection algorithm reduces the number of deployed policies required to be retrieved for analysis against any newly specified federation-level policy, while the conflict analysis algorithm detects inconsistencies relating to the conditional element of a policy rule. We discuss a concrete example in the form of a federated XMPP communication scenario.
