More recently, there have been several XML-based languages proposed for specifying and orchestrating business processes, culminating in WS-BPEL. A significant omission from WS-BPEL is the ability to specify authorization information associating users with activities in the business process and authorization constraints on the execution of activities such as separation of duty. In this paper, we address these deficiencies by developing the RBAC-WS-BPEL and BPCL languages. The first of these provides for the specification of authorization information associated with a business process specified in WS-BPEL, while BPCL provides for the articulation of authorization constraints","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131101671","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}

Recently, Web services for network management has been enabling the investigation of more sophisticate management solutions, even though some concerns related to the Web services performance have been initially exposed, but quickly disappeared after the first research results. In this paper we show that Web services technologies have more to offer to the network management discipline than just bridging established network management protocols and Web services protocols. Particularly we explore the possibility of using Web services composition applied to network management. If successful, Web services composition can bring to network management the solution for some key problems yet to be solved, such as retrieving the information from several different devices and yet being able to use a simple and fast interface at the manager side. We present Web services composition for network management considering two approaches: in the first one a single network device needs to be contacted and its information composed; in the second one, many devices need to be contacted and the information retrieved from them need to be composed. We show that using proper tools we can not only really use Web services composition for network management, but also that such use can be integrated with traditional management technologies that are unlike to be abandoned in short and mid terms","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133929449","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}

It provides a full support for asynchronous outbound operation and event notification in communication services. TARGET addresses an acute issue for Internet applications that today's enterprise NATs and firewalls only allow outbound HTTP request from the inside to the outside and block any request from the outside to the inside, which is a serious problem for two-way Web services. TARGET is a generic solution to allow two-way Web service interaction to traverse legitimately through NATs and strictly configured firewalls; and it is based on two-way SOAP message tunneling, service local registry, and service routing to bridge two-way Web service interaction. A research TARGET system has been implemented and applied to real time communication services, e.g. conferencing. Extensive experiments on TARGET are performed, and its performance with various sizes of SOAP messages is studied. The applicability and feasibility of TARGET for two-way Web service interaction is verified","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117304172","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}

For a composite service, in addition to its functional requirements, QoS requirements are important and deserve a special attention. The central question to a QoS composition problem is how to compose a service from different subcomponent services so that its overall QoS can satisfy certain requirements. In this paper, we propose an agent-based method using fuzzy distributed constraint satisfaction problem (fuzzy DisCSP) techniques to solve this problem. We show that by using the composition structures, local constraints can be constructed and used with DisCSP. We also present an a new algorithm called the fuzzy constraint satisfaction algorithm for distributed environment (FADE) to solve the problem and discuss our experiment in building a prototypical system to prove the feasibility of our approach","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121052588","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 discussion, the value to practitioners of discovering and reusing existing service compositions, captured in workflows, is mostly ignored. This paper presents one solution to workflow discovery. Through a survey with 21 scientists and developers from the myGrid workflow environment, workflow discovery requirements are elicited. Through a user experiment with 13 scientists, an attempt is made to build a gold standard for workflow ranking. Through the design and implementation of a workflow discovery tool, a mechanism for ranking workflow fragments is provided based on graph sub-isomorphism matching. The tool evaluation, drawing on a corpus of 89 public workflows from bioinformatics and the results of the user experiment, finds that the average human ranking can largely be reproduced","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126481673","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 paper, we present PWSSec (process for Web services security) as a process that enables the integration of a set of specific stages into the traditional phases of WS-based systems development providing them with security. PWSSec is composed of three stages, WSSecReq (Web services security requirements), WSSecArch (Web services security architecture) and WSSecTech (Web services security technologies) that allow the specification of WS-specific security requirements, the definition of the WS-based security architecture and the identification of the security standards that the security architecture must deploy, respectively","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"419 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124204761","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}

Two business processes match if they agree on their simple services, their processing order as well as any mandatory or optional requirements for the service. This matching semantics can be formalized by modelling business processes as annotated finite state automata (aFSAs) and deciding emptiness of the intersection aFSA. Computing the intersection of aFSAs and deciding emptiness are computationally expensive, being more than quadratic on the number of states and transitions, thus does not scale for large service repositories. This paper presents an approach for indexing and matching business processes modeled as aFSAs, for the purpose of service discovery. Evaluation of this approach shows a performance gain of several orders of magnitude over sequential matching and a linear complexity with regard to the data set size","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132612385","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 architecture supports both \"instance monitors\" that deal with the execution of a single instance of BPEL process, as well as \"class monitors\" that report aggregated information about all the instances of a BPEL process. We also define a language for the specification of instance and class monitors. The language allows for specifying boolean, statistic, and time-related properties.
