As a result, component middleware are adding support for composite web services. Till recent past, most of these middleware were employed in tiered architectures. However, nature of call graphs differs in SOA. In this paper we revisit concurrency and deadlock issues that appear due to hosting SOA applications on middleware with prevalent thread allocation schemes. We propose a novel thread allocation scheme which performs an off-line analysis of web services call graphs and equips containers with essential information. At run-time, containers use this information and do not consult any central point or each other for thread allocation decisions. This makes our approach practical and scalable. We demonstrate, through simulations, that our approach can provide significant throughput improvements when compared with traditional thread allocation schemes.","PeriodicalId":340887,"journal":{"name":"Companion '08","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127242621","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}

This paper aims to provide a comprehensive taxonomy and experimental evaluation using real-world data. While the rate of change of data on a day-to-day basis has the greatest influence on the duplication in backup data, we investigate the duplication inherent in this data, independent of rate of change of data or backup schedule or backup algorithm used. Our experimental results show that between different deduplication techniques the space savings varies by about 30%, the CPU usage differs by almost 6 times and the time to reconstruct a deduplicated file can vary by more than 15 times.","PeriodicalId":340887,"journal":{"name":"Companion '08","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124919148","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}

Security, a key middleware service, requires variations at design-time, deploy-time as well as runtime.

In this demonstration, we introduce and present the AspireRfid middleware platform using demonstrators in the area of Supply Chain management and Near Field Communications. The AspireRfid platform provides support for non-trivial RFID applications in several fields including supply-chain management, logistics, access control, asset management and pharmaceuticals. In this demonstration we present a traceability application for logistics and supply chain management, as well as a pick and pack application. AspireRfid implements several building blocks of the EPCglobal architecture. However, it also extends the EPCglobal architecture with several middleware modules, which can greatly facilitate RFID application development and deployment. Hence, prior to presenting the demonstrations, we provide a brief discussion of the EPCglobal architecture and the extensions implemented by AspireRFid. We end-up with an illustration of the demonstrators.","PeriodicalId":340887,"journal":{"name":"Companion '08","volume":"135 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128794763","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}
