It provides a loose coupled and implementation neutral infrastructure for distributed applications. On the other hand, multi agent systems has evolved as distributed system in context of autonomic computing having ultimate aim of self-managing systems to overcome their rapidly growing complexity and to enable their further growth. In this paper, we present our solution for dynamic and seamless integration of type the distributed systems. It would help in facilitating the requirements of next generation distributed applications requiring higher demands and complexity. The AgentWeb Gateway acts as middleware between both the technologies for dynamic integration and provides protocol transformations including service discovery, service description and service invocation.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126263131","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}

Boldyreff","doi":"10.1109/WETICE.2005.37","DOIUrl":"https://doi.org/10.1109/WETICE.2005.37","url":null,"abstract":"In distributed software engineering, the role of informal communication is frequently overlooked. Participants simply employ their own ad-hoc methods of informal communication. Consequently such communication is haphazard, irregular, and rarely recorded as part of the project documentation. Thus, a need for tool support to facilitate more systematic informal communication via awareness has been identified. The tool proposed is based on the provision of awareness support that recognizes the complete context of the evolution of software artefacts rather than single events. Peer-to-peer (P2P) networking has been successfully employed to develop various distributed software engineering support tools. However, there are scalability problems inherent in naive P2P networks. To this end a semantic overlay network organization algorithm has been developed and tested in simulation prior to deployment as part of a forthcoming awareness extension to the Eclipse environment. The simulation verified that the self-organization algorithm was suitable for arranging a P2P network but several unexpected behaviors were observed. These included wandering nodes, starved nodes, and local maxima. Each of these problems required modification of the original algorithm design to solve or ameliorate them.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131111329","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}

Different modeling techniques have been invented for the abstract description of certain aspects of dynamic system behaviour. Nowadays process models are also an accepted part of service oriented process design. Although service oriented architecture (SOA) is the aim, rather isolated processes are the starting point for executable code generation and not the changing functionality distribution the system offers. Thus we claim the system view, necessary for process lifecycle management, is missing. Moreover, in the context of Web service composition, a vertical, bi-directional model driven approach allows for manifold allocation of e.g. testing, validation or binding tasks within the layer stack of MDAs (model driven architecture). In this paper, we discuss two distinctive proposals for model driven service composition, followed by a comparison of representative mapping scenarios offered by IBM and Microsoft.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134095143","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 was the first meeting devoted to the study of the emerging field of Cooperative Information Systems and P2P networks or Cooperative P2Pbased Information Systems (COPS). P2P Systems are popular because of the many benefits they offer: adaptation, self-organization, fault tolerance, and massive distribution and replication of large number of resources. The P2P environment is particularly challenging to work in Collaborative Information Systems because of the scale of the network and fault-tolerant nature of peers that characterize most P2P systems today. However, the P2P systems research community has focused on search and security aspects. Collaboration has been mainly viewed as an architectural paradigm instead of as an application framework for P2P systems. There is a need for a next generation tools for the development of applications that must integrate, for example, web servers network and p2p clients. Research communities working in database and distributed systems have included these topics in their agenda. However, a more specialized workshop could be an interesting place to exchange new ideas in the field of COPS.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"441 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122479204","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}

Protection from nefarious individuals and organizations requires a solution that is more a methodology than a one time fix. One aspect of this methodology is having the knowledge of which network ports a computer has open to the world. These network ports are essentially the doorways from the Internet into the computer. An assessment method which uses the nmap software to scan ports has been developed to aid system administrators (SAs) with analysis of open ports on their system(s). Additionally, baselines for several operating systems have been developed so that SAs can compare their open ports to a baseline for a given operating system. Further, the tool is deployed on a Web site where SAs and users can request a port scan of their computer. The results are then emailed to the requester. This tool aids users, SAs, and security professionals by providing an overall picture of what services are running, what ports are open, potential trojan programs or back doors, and what ports can be closed.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128053666","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}
