File systems have evolved various techniques to provide crash consistency, in which journaling technique is one of the most important. Unfortunately, journaling introduces a write-twice problem: the write traffic is firstly written to the journal space, and latter is written back to the file system space. This problem is critical when version consistency is required in data management applications. To address this problem, we present sJournal, a smart journaling layer which can provide version consistency to the upper file systems efficiently. The key idea of sJournal is to understand the block I/O traffic issued from upper file systems, and redirect the I/O traffic between the journal space and the file system space intelligently. This includes four techniques: 1) detect the upper file system and extract the disk block allocation status, 2) identify and log all the overwrite traffic to the journal space while issuing non-overwrite traffic to the file system space directly, 3) redirect read traffic to the journal space if the target block is logged, 4) checkpoint all the logged data to the file system space at proper timing. We implemented a prototype of sJournal, and incorporated it with Ext3. Through experiments, we compared the performance of Ext3 running with ordered mode, data journal mode and sJournal, respectively. The results show that Ext3 with sJournal support can provide comparable performance to ordered journal mode, while ensuring the version consistency guaranteed in data journal mode.","PeriodicalId":186621,"journal":{"name":"2014 9th IEEE International Conference on Networking, Architecture, and Storage","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122426494","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 performance bottleneck has gradually shifted from the processors to the interconnection network. Traditional electrical interconnection, because of its low bandwidth, high delay and low interconnection density, becomes one of the constraints of high-performance computer(HPC)'s further improvement. Due to the inherent limitations of the electrical interconnection network, optical interconnection has become a feasible way to improve the performance. A Three-Dimensional Optical Interconnection Network (TDOIN) with low latency and high throughput was put forward in our previous work. An accurate mathematical model can help us design and optimize the optical networks. However, there is not a mathematical model which can provide an accurate analysis for TDOIN. To make better use of the network, we propose a steady-state model to evaluate TDOIN's network characteristics in this paper. This mathematical model is constructed by using Probability Theory. The results of the model analysis and the simulation shows that our model can accurately depict behaviors of TDOIN at steady state.","PeriodicalId":186621,"journal":{"name":"2014 9th IEEE International Conference on Networking, Architecture, and Storage","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126143402","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}

Due to the name space being many orders of magnitude larger and more complex than IP address space, such architectures pose many significant challenges on design of routers and routing algorithms. IP forwarding algorithms are no longer applicable and cannot reach the satisfactory performance. In this paper, we ask ourselves the following question: how fast can the longest prefix name based lookup be? This is a key question to answer in order for named data networking architectures to be potentially successful. As an attempt to answer this question, we present a framework of fast longest prefix name lookup, based on a name space reduction scheme we proposed for named data networking. We also investigate feasible implementations on both CPU and GPU platforms. We demonstrate that we can achieve name lookup throughput as high as more than 37 and 70 million packets per second, respectively, on off-theshelf general-purpose CPU and GPU platforms. These results suggest that achieving high-performance lookup in named data networking architectures is not only feasible but also practical.","PeriodicalId":186621,"journal":{"name":"2014 9th IEEE International Conference on Networking, Architecture, and Storage","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127027710","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}

Time-to-market of these products has been shortened to an extreme, nearly 8 to 12 months. To reduce production period, hardware architects generally combine well-tuned IP cores in their designs. To guarantee the process of SoC software development, which will finally decide the release time of products, a fast prototyping simulation platform for SoC software development should be available as soon as possible after hardware design. However, state-of-the-art SoC simulators lack the support for fast integration of IP core and require time-consuming compiler chain modifications for new instructions. In this paper, we present Prism, an extensible and easy-to-use full-system SoC simulation platform for SoC software development. Two mechanisms are designed and implemented to support fast prototyping for new IP core simulation or new instruction extension without compiler tool chain modifications. First, a hardware and software hybrid mechanism is proposed for IP core fast prototyping. A seamless interface is used to eliminate the differences among IP cores. Second, a configurable library mechanism is designed for new instruction extension. Register dependence can be maintained for detailed timing simulation without compiler tool chain modification. In such a design, the major effort for extension is to specify the elaborate common customization interface. Experimental results show these mechanisms only involve about 0.36% runtime overhead. Based on RPSim, a graduate student only needs write about 40 lines of code and takes less than half an hour to extend a new IP core simulation in RPSim.","PeriodicalId":186621,"journal":{"name":"2014 9th IEEE International Conference on Networking, Architecture, and Storage","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116745065","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 has prompted the rapid development of jamming-resistance infrastructure consisting of multiple dynamic access points such as proxies, anonymous communication nodes and covert communication nodes. However, the channel between user and access point has become an emerging attacking target for the adversary. Once the channel is detected and identified by the adversary, the channel will be interrupted. Though users can require new access points from the infrastructure and resume the communication to their destination, the service quality will be downgraded dramatically due to the time-consuming bootstrapping process. In this paper, a moving target framework is proposed to improve the network service accessibility, which combines both time-consuming bootstrapping and frequent and low-cost channel refreshing operations. The constant channel refreshing operations is imported to limit the adversary's ability of detecting and blocking communications, thus to make the lifespan of effective communication longer. With theoretical and simulating analysis, the optimized refreshing strategy is proposed, which can help improve service accessibility.","PeriodicalId":186621,"journal":{"name":"2014 9th IEEE International Conference on Networking, Architecture, and Storage","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125064238","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}
