This paper presents Policy-based Federation (PBF) architecture for interworked Future Internet Virtualized Infrastructures (VIs). Each VI is an individually managed autonomous domain. Users may request slices of virtual resources across the federation, managed and controlled via inter-domain policies that abide by agreed upon federated SLAs. The key component of our PBF architecture is a Policy Service,...
Policies could potentially be an important and cost-effective technique for building and managing pervasive systems. Historically, policy-based systems have been built using a policy environment that supports the specification and enforcement of policies for a range of management concerns such as adaptation and security. In this short paper we describe our experiences with challenges in building human-centric...
In this paper, we first present the design of the Cross-Domain Language (CDL), the first attempt to date to design a high-level end-user language for the specification of cross-domain information-release policies. We then discuss our experiences and lessons learned in implementing CDL policies on lower-level general-purpose language frameworks such as Ponder2 and highlight future directions for language...
Policies form an important part of management and can be an effective means of implementing self-adaptation in pervasive systems. Most policy-based systems focus on large-scale networks and distributed systems. Consequently, they are often fragmented, dependent on infrastructure and lacking flexibility and extensibility. This paper presents Ponder2, a novel policy system that is suitable for a wide...
Policies form an important part of management activities and are an effective means of implementing self-adaptation in pervasive systems. Many policy- based systems designed to date focus on large-scale networks and distributed systems. Consequently, they are often fragmented, dependent on infrastructure and lacking flexibility and extensibility. This demonstration presents Ponder2, a self-contained,...
