In this paper, we present software and hardware approaches for transparent line-rate encoding and decoding of SOAP traffic for alleviating network bandwidth bottlenecks. The proposed approaches are significantly lighter weight than gzip and binary XML encoding techniques while achieving better compression ratios. First we present a software-based scheme with a linear runtime that uses a finite set of pre-selected message templates for differential encoding of SOAP messages. We propose generating the templates by extracting the longest common subsequence from a representative set of SOAP messages encountered during the service operation. Next we present an architecture for line-rate implementation of data differencing functionality in hardware. As compared to the software-based scheme, the hardware design allows higher flexibility in the template selection and message encoding without compromising the encoder throughput. We test both schemes on a sample workload running on a SOAP based Business Intelligence software platform. Our results show that the proposed techniques can achieve an average of 10X reduction in the overall SOAP traffic. Furthermore, we show that the differentially encoded data can be further compressed by gzip to achieve a combined 15-17X reduction in the message sizes as compared to less than 5X compression obtained when using gzip by itself.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115668724","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}

Orgun","doi":"10.1109/ICWS.2014.58","DOIUrl":"https://doi.org/10.1109/ICWS.2014.58","url":null,"abstract":"Cloud computing services have been increasingly considered by business as a viable option for reducing IT expenditure. The highly automated and agile nature of cloud services offer businesses low cost, high efficiency and flexibility benefits. However, there are often associated problems with unmanaged accountability such as lack of disclosure of service obligations, mechanisms for detection for obligation fulfilment or determination of liable party if an obligation is violated. This paper analyses the accountability properties of a cloud service and proposes an accountable cloud service (ACS) model to address those problems. The ACS model is underpinned by a hybrid logic system called Dynamic Logic for Accountability (DLA) extended from Dynamic Logic. ACS provides an intuitive notation for modeling service collaboration diagrams based on a reduced version of BPMN2.0 to capture the fulfillment of service obligations. We also propose an Obligation Flow Diagram (OFD) as a simple method for conflict resolution and verification for the ACS model. The ACS model enables obligation specification, decomposition, validation, machine-interpretation, monitoring and reasoning, and ultimately facilitates accountability in cloud service consumption. Using Amazon S3 service as a case study, we show how to address those known accountability problems using our ACS model. Finally we discuss the applicability of our model to cloud services in general.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121873505","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}

However, most existing work only detects the violation while not consider how to enforce the properties so that the constraint can not be violated at runtime. To address this limitation, this paper presents EnforceBCL, a framework for enforcing data-centric properties for concurrent service-based applications. Users of EnforceBCL can specify the properties to be enforced using the expressive behavior constraint enforcement language. Data-centric property is enforced at runtime by blocking the process whose next action would violate it. The impacted processes can be unblocked and allowed to execute when the specified property eventually reaches a safe state. EnforceBCL also provides the mechanism to detect possible deadlock during the enforcement of the property, and executes corresponding handler to solve the deadlock. To evaluate the effectiveness and efficiency of the proposed approach, we conducted several experiments. Results show that EnforceBCL is able to effectively enforce data-centric properties for concurrent service-based applications and also incurs less performance overhead.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130691278","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}

Thus, it is significant to evaluate the trustworthiness of the service providers along the social trust paths from a service consumer to a service provider. However, there are usually many social trust paths between an unknown service consumer and service provider. Thus, a challenging problem is how to effectively and effciently find those social trust paths that can yield trustworthy trust evaluation results based on the requirements of a service consumer particularly in the real-time OSN environments. In this paper, we first present a contextual trust-oriented social network structure and a concept of Quality of Trust (QoT). We then model the multiple social trust paths finding with end-to-end QoT constraints as the Multiple Constrained K Optimal Paths (MCOP-K) selection problem, which is NP-Complete. To deal with this challenging problem, based on the Monte Carlo method and our optimization search strategies, we propose a new efficient and effective approximation algorithm D-MCBA. The results of our experiments conducted on a real-world dataset of OSNs illustrate that D-MCBA can efficiently identify the social trust paths with better quality than our previously proposed MONTE K algorithm that is the most promising algorithm for the social trust path finding in OSNs.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130950973","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}
