Yue, Haining Wang","doi":"10.1109/DSN.2009.5270329","DOIUrl":"https://doi.org/10.1109/DSN.2009.5270329","url":null,"abstract":"The most commonly used request processing model in multithreaded web servers is thread-per-request, in which an individual thread is bound to serve each web request. However, with the prevalence of using template techniques for generating dynamic contents in modern web servers, this conventional request processing model lags behind and cannot provide efficient resource management support for template-based web applications. More precisely, although content code and presentation code of a template-based dynamic web page can be separated into different files, they are still processed by the same thread. As a result, web server resources, especially database connection resources, cannot be efficiently shared and utilized. In this paper, we propose a new request scheduling method, in which a single web request is served by different threads in multiple thread pools for parsing request headers, performing database queries, and rendering templates. The proposed scheme ensures the high utilization of the precious database connections, while templates are being rendered or static contents are being served. We implemented the proposed scheme in CherryPy, a representative template-enabled multithreaded web server, and we evaluated its performance using the standard TPC-W benchmark implemented with the Django web templates. Our evaluation demonstrates that the proposed scheme reduces the average response times of most web pages by two orders of magnitude and increases the overall web server throughput by 31.3%under heavy loads.","PeriodicalId":376982,"journal":{"name":"2009 IEEE/IFIP International Conference on Dependable Systems & Networks","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122976299","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}

Hence, electric power utilities need to extend risk management frameworks with adequate tools for assessing consequences of ICT (Information and Communication Technologies) threats on their critical business. This requires realistic probability estimates to cyber threat occurrences and consequent failure modes. Due to data sensitivity and rapid discovery of new vulnerability exploits, historical data series of ICT failures affecting power control infrastructures are not sufficient for a timely risk treatment. Such lack of data can partially be overcome by setting up testbeds to run controlled experiments and collect otherwise unavailable data related to cyber misbehaviours in power system operation. Within the project CRUTIAL (CRitical UTility InfrastructurAL resilience) two testbed platforms have been set up for experimentally evaluating malicious threats on macro and micro grid control scenarios. Results from experimental campaigns are analyzed in the paper by means of an evaluation framework.","PeriodicalId":376982,"journal":{"name":"2009 IEEE/IFIP International Conference on Dependable Systems & Networks","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132961177","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}
