And some, or all, of such records, pertaining to a given patient, may have to be transfered to a provider to facilitate the treatment of this patient. Such transfer needs to be done quickly, because delays may adversely impacts the quality and cost of healthcare; and may, in some cases be a matter of life or death. But fast electronic transfer presents serious danger to the privacy and integrity of these records. This raises the need for governance, that is, for the formulation and enforcement of the societal policies and laws pertaining to the exchange of electronic healthcare records between the members of the often large and heterogeneous networks of healthcare providers. This paper introduces a reference model for such governance, which has the following characteristics, among others: (a) decentralized, and thus scalable, enforcement mechanism; (b) seamless and secure interoperation between health care providers operating under different policies, and under different administrative domains; (c) support for the naturally hierarchical organization of the policies that govern the exchange of health care records; (d) the ability to change policies while the system governed by them continues to operate.","PeriodicalId":143330,"journal":{"name":"2010 IEEE International Symposium on Policies for Distributed Systems and Networks","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128112493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Storage cloud providers often employ Storage Area Networks (SANs) to provide elasticity, rapid adaptability to changing demands, and policy based automation. As storage capacity grows, the storage environment becomes heterogeneous, increasingly complex, harder to manage, and more expensive to operate. This paper presents PGML (Policy Generation for largescale storage infrastructure configuration using Machine Learning), an automated, supervised machine learning framework for generation of best practices for SAN configuration that can potentially reduce configuration errors by up to 70% in a data center. A best practice or policy is nothing but a technique, guideline or methodology that, through experience and research, has proven to lead reliably to a better storage configuration. Given a standards-based representation of SAN management information, PGML builds on the machine learning constructs of inductive logic programming (ILP) to create a transparent mapping of hierarchical, object-oriented management information into multi-dimensional predicate descriptions. Our initial evaluation of PGML shows that given an input of SAN problem reports, it is able to generate best practices by analyzing these reports. Our simulation results based on extrapolated real-world problem scenarios demonstrate that ILP is an appropriate choice as a machine learning technique for this problem.

For instance, in some situations, reaching a near pareto-optimal solution is desirable even though it requires that an exhaustive search on all attributes must be performed. In other situations, time might be more valuable and therefore reaching an agreement in a timely manner might have a higher priority. In order to address many different types of negotiation goals and scenarios, there is a need for a flexible negotiation system that can incorporate various alternatives and that is easily extensible and configurable. In this paper, we provide a generic negotiation system that can support many types of negotiation protocols. The proposed system acts as a third party that facilitates the negotiation process between multiple entities and allows them to choose a common negotiation goal and a desired negotiation protocol. We will provide a demonstration of the tool at the conference.","PeriodicalId":143330,"journal":{"name":"2010 IEEE International Symposium on Policies for Distributed Systems and Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115160604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, it supports policy-aware application programming. Application components can request evaluations of policy expressions and decisions in order to govern their behavior depending on global system state and environment conditions. That rich functionality has to be provided very efficiently since the distributed system consists of resource-constrained devices. The model-based management (MBM) approach is applied separating comfortable tool-assisted policy definition and refinement at design time from lightweight runtime policy enforcement. New enhancements of MBM extend the policy refinement to the derivation of ECA rules. The new backend functions generate executable Java byte code for policy expressions and decisions as well as for policy rules. The code is appropriately partitioned and allocated to the devices. A simplified healthcare scenario demonstrates the approach and its application.","PeriodicalId":143330,"journal":{"name":"2010 IEEE International Symposium on Policies for Distributed Systems and Networks","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127636017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
