An important research question is how quality of service models can inform runtime adaptation. We sketch one solution to this question by application of control theory to improve performance of queued systems by means of architectural adaptation. Previous research by our group has shown how Auto Regressive Integrated Moving Average techniques can be utilized to forecast how Quality of Service (QoS) characteristics are likely to evolve in the near future. This is particularly important in cases where systems can be adapted to counter QoS constraint violations. In this paper, we show how, given a similar type of QoS characteristic forecasts, strategies of architectural adaptation can be implemented that pre-emptively avoid QoS violations. The novelty of our approach is that we use classical control theory to ensure that our adaptation strategies are stable, in the sense that they do not oscillate between choices. We provide a description of how our control theoretic model can be implemented using context-based interception in .NET via model driven engineering.","PeriodicalId":181454,"journal":{"name":"2007 Eleventh International IEEE EDOC Conference Workshop","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121994935","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}

The collected data is analyzed and used by various high-level services, like user profiling, accounting, security auditing, and system health monitoring. In this paper, we present architecture and performance evaluation of usage tracking components for service-oriented middleware systems. Presented middleware components are designed as loosely-coupled usage tracking services, which brings two important benefits. Usage tracking services can be seamlessly integrated with various service-oriented systems without disturbing their operation. Since usage tracking services are loosely-coupled, system users can dynamically deploy and manage multiple usage tracking configurations.","PeriodicalId":181454,"journal":{"name":"2007 Eleventh International IEEE EDOC Conference Workshop","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123981672","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}

In this way, viewpoints can be defined in a more concise and harmonized way.

{"title":"Privacy Issues in Middleware for Service-oriented Applications","authors":"P. Hung","doi":"10.1109/EDOCW.2007.25","DOIUrl":"https://doi.org/10.1109/EDOCW.2007.25","url":null,"abstract":"Privacy helps to establish personal autonomy and create individualism. Privacy is a state or condition of limited access to a person. In particular, information privacy relates to an individual's right to determine how, when, and to what extent information about the self will be released to another person or to an organization. It can be said that privacy is a much broader concept than security; privacy protection is based on security protection. Security may enable privacy protection from authorized access, but security alone cannot provide privacy. Service-Oriented Computing (SOC) has recently gained a lot of attention both in industry and academic areas. However, its characteristics can not be easily solved using existing distributed computing technologies. The composition and interaction issues have been the central concerns because service-oriented applications are composed of autonomous, heterogeneous, and distributed processes. Middleware is thus proposed to serve as a solution to manage and provision service-oriented applications. Middleware is computer software that connects software components or applications in a distributed environment. Middleware includes different systems to support application development and delivery such as Web servers, application servers, and content management systems. To tackle the complexity of the interactions among services from various organizations, complex process requirements can be decomposed into different types of information flows, such as control, and data. This talk will give an overview of the research on privacy issues in this context and discuss the future research directions.","PeriodicalId":181454,"journal":{"name":"2007 Eleventh International IEEE EDOC Conference Workshop","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125564528","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}

Wherever a correspondence is declared, any real world entity that is represented by a term in one viewpoint must also satisfy the requirements placed by the occurrence of the corresponding term in the other viewpoint. Although this idea represents an intuitively simple and satisfying way of talking about the design of complex systems, the idea of a correspondence is not as simple as it might, at first sight, appear. This paper uses simple examples to illustrate some of the complexities resulting from the coupling of object models and examines the consequences for claims of conformance to the complete system of specifications.","PeriodicalId":181454,"journal":{"name":"2007 Eleventh International IEEE EDOC Conference Workshop","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116117716","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}

To achieve this goal, it is essential to use a Web-services compatible framework that tolerates not only crash faults, but Byzantine faults as well, due to the untrusted communication environment in which the Web services operate. In this paper, we describe the design and implementation of such a framework, called BFT-WS. BFT-WS is designed to operate on top of the standard SOAP messaging framework for maximum interoperability. It is implemented as a pluggable module within the Axis2 architecture, as such, it requires minimum changes to the Web applications. The core fault tolerance mechanisms used in BFT-WS are based on the well-known Castro and Liskov's BFT algorithm for optimal efficiency. Our performance measurements confirm that BFT-WS incurs only moderate runtime overhead considering the complexity of the mechanisms.","PeriodicalId":181454,"journal":{"name":"2007 Eleventh International IEEE EDOC Conference Workshop","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115899082","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}
