However, since most space CPUs have not integrated on-chip SpaceWire Controllers, it is important to design efficient SpaceWire Controllers with the assistance of external FPGA chips. As the speed of SpaceWire bus exceeds hundreds of Mbps, the SpaceWire Controller requires plenty of memory resources to send and receive packages. Nevertheless, the storage resources of radiation-tolerant space FPGA are severely constrained, especially for the commonly used antifuse FPGA families, i.e., actel RTAX series. Therefore, it is very critical and challenging to design a SpaceWire bus controller with few on-chip memory resource requirements. In this paper, we propose a novel design, SMC (Shared Memory based spacewire Controller). In SMC, the FPGA chip which implements the SpaceWire Controller is connected to the CPU memory buses, while the Shared Memory Chip, which contains the reading and writing FIFOs, is connected to the FPGA and shared by SpaceWire Controller and CPU. We carefully design the sub-modules of the SMC model, including the CPU interface module, SpaceWire transceiver module, flow control module and SRAM arbitration access module, etc.. To enhance the system performance, we design an efficient interrupt-based packet sending and receiving mechanism. We implement the SMC logic within an Actel A3P1000 FPGA, and evaluate its performance in a practical OBC platform. Experimental results show that, our SMC design can effectively reduce the memory requirements of SpaceWire controllers, and provides an effective solution to implement SpaceWire Controller of CPU based on FPGA.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123446412","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}

Although the frameworks in charge of managing virtual machines (VM) on pools of physical ones (PM) have been significantly improved, enabling to manage large-scale infrastructures composed of hundreds of PMs, most of them do not efficiently handle the aforementioned objective. The main reason is that advanced scheduling policies are subject to important and hard scalability problems, that become even worse when VM image transfers have to be considered. In this article, we provide a new validation of the Distributed VM Scheduler approach (DVMS) in a twofold manner. First, we provide a formal proof of the algorithm based on temporal logic. Second, we discuss large-scale evaluations involving up to 4.7K VMs distributed over 467 nodes of the Grid'5000 testbed. As far as we know, these experiments constitute the largest in vivo validation that has been performed so far with decentralized VM schedulers. These results show that a cooperative approach such as ours permits to fix overload problems in a reactive and scalable way.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130492659","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}

One of the critical needs in order to deal with this \"data deluge\" is an efficient, scalable and reliable storage. However, the storage services proposed by cloud providers suffer from high latencies, trading performance for availability. One alternative is to federate the local virtual disks on the compute nodes into a globally shared storage used for large intermediate or checkpoint data. This collocated storage supports a high throughput but it can be very intrusive and subject to failures that can stop the host node and degrade the application performance. To deal with these limitations we propose DataSteward, a data management system that provides a higher degree of reliability while remaining non-intrusive through the use of dedicated compute nodes. DataSteward harnesses the storage space of a set of dedicated VMs, selected using a topology-aware clustering algorithm, and has a lifetime dependent on the deployment lifetime. To capitalize on this separation, we introduce a set of scientific data processing services on top of the storage layer, that can overlap with the executing applications. We performed extensive experimentations on hundreds of cores in the Azure cloud: compared to state-of-the-art node selection algorithms, we show up to a 20% higher throughput, which improves the overall performance of a real life scientific application up to 45%.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129872642","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}

A variety of routing metrics have been proposed to enhance the performance of routing protocols. Considering the forwarding behavior of neighbor node in the design of a routing metric would address the most generic packet dropping attacks in wireless mesh network (WMN). The existing routing metrics to address packet dropping attack in WMN only consider selfish mesh routers. On the other hand, to the best of our knowledge no such routing metric has been proposed to address the malicious behavior of mesh routers in a network. In this paper, we propose an airtime link metric AFC (Airtime Forwarding Capability), that considers both selfish and malicious behavior of mesh routers. AFC is computed using local station level measurements and does not require direct cooperation from any neighbor node, thereby avoiding neighbor lying attacks. The analysis of proposed metric shows that it satisfies the required design properties of a routing metric. The experimental results confirm the performance enhancement by accounting for the malicious behavior of mesh routers.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132684092","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}
