Streszczenie:

Advancements in remote sensing technology and very-large-scale integrated circuit (VLSI) have significantly augmented the real-time processing capabilities of spaceborne synthetic aperture radar (SAR), thereby enhancing terrestrial observational capacities. However, the inefficiency of voluminous data storage and transfer inherent in conventional methods has emerged as a technical hindrance, curtailing real-time processing within SAR imaging systems. To address the constraints of a limited storage bandwidth and inefficient data transfer, this study introduces a three-dimensional cross-mapping approach premised on the equal subdivision of sub-matrices utilizing dual-channel DDR3. This method considerably augments storage access bandwidth and achieves equilibrium in two-dimensional data access. Concurrently, an on-chip data transfer approach predicated on a superscalar pipeline buffer is proposed, mitigating pipeline resource wastage, augmenting spatial parallelism, and enhancing data transfer efficiency. Building upon these concepts, a hardware architecture is designed for the efficient storage and transfer of SAR imaging system data, based on the superscalar pipeline. Ultimately, a data storage and transfer engine featuring register addressing access, configurable granularity, and state monitoring functionalities is realized. A comprehensive imaging processing experiment is conducted via a “CPU + FPGA” heterogeneous SAR imaging system. The empirical results reveal that the storage access bandwidth of the proposed superscalar pipeline-based SAR imaging system’s data efficient storage and transfer engine can attain up to 16.6 GB/s in the range direction and 20.0 GB/s in the azimuth direction. These findings underscore that the storage exchange engine boasts superior storage access bandwidth and heightened data storage transfer efficiency. This considerable enhancement in the processing performance of the entire “CPU + FPGA” heterogeneous SAR imaging system renders it suitable for application within spaceborne SAR real-time processing systems.

Now, the quality of higher speed and larger capacity are required to the real-time storage system. This paper designs a high-speed and large-capacity storage system which uses FPGA as the master of SOPC system controlling NAND Flash chips. This system puts forward an advanced storage structure which has several NAND Flashes with multi-buses, forming a parallel pipeline design. By using the key technologies of bad block management and the ECC algorithm, which greatly avoids the influence of the invalid block to the storage system and reduces the probability of error data as well. It can not only improve the storage bandwidth and capacity substantially, but also ensure the reliability of the storage system effectively. As a result, the storage system achieves the capacity of 1.5TB and the bandwidth of 1280MBps. Also, this system uses high-speed exchange interface to link to the external network, which achieve the real-time transmission and control of data, and make the storage system standard, universal, and scalable.

Streszczenie:

To protect data in cloud storage, fault tolerance and efficient recovery become very important. Recent studies have developed numerous solutions based on erasure code techniques to solve this problem using functional repairs. However, there are two limitations to address. The first one is consistency since the Encoding Matrix (EM) is different among clouds. The other one is repairing bandwidth, which is a concern for most of us. We addressed these two problems from both theoretical and practical perspectives. We developed BMCloud, a new low repair bandwidth, low maintenance cost cloud storage system, which aims to reduce repair bandwidth and maintenance cost. The system employs both functional repair and exact repair while it inherits advantages from the both. We propose the JUDGE_STYLE algorithm, which can judge whether the system should adopt exact repair or functional repair. We implemented a networked storage system prototype and demonstrated our findings. Compared with existing solutions, BMCloud can be used in engineering to save repair bandwidth and degrade maintenance significantly.

Cost effective, smooth multimedia streaming to the remote customer through the distributed “video on demand” architecture is the most challenging research issue over the decade. The hierarchical system design is used for distributed network to satisfy more requesting users. The distributed hierarchical network system contains all the local and remote storage multimedia servers. The hierarchical network system is used to provide continuous availability of the data stream to the requesting customer. In this work, we propose a novel data stream that handles the methodology for reducing the connection failure and smooth multimedia stream delivery to the remote customer. The proposed session based single-user bandwidth requirement model presents the bandwidth requirement for any interactive session like pause, move slowly, rewind, skip some of the frame, and move fast with some constant number of frames. The proposed session based optimum storage finding algorithm reduces the search hop count towards the remote storage-data server. The modeling and simulation result shows the better impact over the distributed system architecture. This work presents the novel bandwidth requirement model at the interactive session and gives the trade-off in communication and storage costs for different system resource configurations.

Streszczenie:

A clustered distributed storage system (DSS), also called a rack-aware storage system, is a distributed storage system in which the nodes are grouped into several clusters. The communication between two clusters may be restricted by their connectivity; that is to say, the communication cost between nodes differs depending on their location. As such, when repairing a failed node, downloading data from nodes that are in the same cluster is much cheaper and more efficient than downloading data from nodes in another cluster. In this article, we consider a scenario in which the failed nodes only download data from nodes in the same cluster, which is an extreme and important case that leverages the fact that the intra-cluster bandwidth is much cheaper than the cross-cluster repair bandwidth. Also, we study the problem of repairing multiple failures in this article, which allows for collaboration within the same cluster, i.e., failed nodes in the same cluster can exchange data with each other. We derive the trade-off between the storage and repair bandwidth for the clustered DSSs and provide explicit code constructions achieving two extreme points in the trade-off, namely the minimum storage clustered collaborative repair (MSCCR) point and the minimum bandwidth clustered collaborative repair (MBCCR) point, respectively.

Streszczenie:

“Hybrid Cloud Storage” (HCS) is a widely adopted framework that combines the functionality of public and private cloud storage models to provide storage services. This kind of storage is especially ideal for organizations that seek to reduce the cost of their storage infrastructure with the use of “Public Cloud Storage” as a backend to on-premises primary storage. Despite the higher performance, the hybrid cloud has latency issues, related to the distance and bandwidth of the public storage, which may cause a significant drop in the performance of the storage systems during data transfer. This issue can become a major problem when one or more private storage nodes fail. In this paper, we propose a new framework for optimizing the data uploading process that is currently used with hybrid cloud storage systems. The optimization is concerned with spreading the data over the multiple storages in the HCS system according to some predefined objective functions. Furthermore, we also used Network Coding technics for minimizing data transfer latency between the receiver (private storages) and transmitter nodes.

Multimedia is inconvenient to use, difficult to maintain, and redundant in data storage. In order to solve the above problems and apply cloud storage to the integration of university teaching resources, this paper designs a virtualized cloud storage platform for university multimedia classrooms. The platform has many advantages, such as reducing the initial investment in multimedia classrooms, simplifying management tasks, making maximum use of actual resources and easy access to resources. Experiments and analysis show the feasibility and effectiveness of the platform. Aiming at the problems of the single-node repair algorithm of the existing multimedia cloud storage system, the limited domain is large, the codec complexity is high, the disk I/O (Input/Output) cost is high, the storage overhead and the repair bandwidth are unbalanced, and a network coding-based approach is proposed. Multimedia cloud storage. System single node repair algorithm. The algorithm stores the grouped multimedia file data in groups in the system, and performs XOR (exclusive OR) on the data in the group on the GF(2) finite field. When some nodes fail, the new node only needs to be connected. Two to three non-faulty nodes in the same group can accurately repair the data in the failed node. Theoretical analysis and simulation results show that the algorithm can reduce the complexity and repair of the codec, and reduce the disk I/O overhead. In this case, the storage cost of the algorithm is consistent with the storage cost based on the minimum storage regeneration code algorithm, and the repair bandwidth cost is close to the minimum bandwidth regeneration code algorithm.

Streszczenie:

Distributed storage systems provide fast and reliable access to data by intro- ducing redundancy for stored les. The most common approach of adding re- dundant information is by repetition and erasure codes. Two main processes in a distributed storage system are reconstruction of original le and regenerat- ing a new node. These two processes require bandwidth, which are termed as reconstruction-bandwidth and repair-bandwidth. The current literature treat- s these two processes separately. That is, there are methods to reduce the reconstructing bandwidth without considering the repair-bandwidth, and also there are methods to reduce the repair-bandwidth. We study these two pro- cesses together and try to jointly minimize the reconstruction-bandwidth and repair-bandwidth. We observe a method that has the minimum reconstruction- bandwidth might have large amount of repair-bandwidth and vice versa. We propose codes which minimizes the sum of the repair-bandwidth and reconstruction- bandwidth. The main contribution of this thesis is nding an value of repair locality r (number of nodes connected during node repair) and devising two coding meth- ods in which total bandwidth approximates to be half reduced compared with MSR and MBR when k ! 1 under the condition that 1 6 r 6 k.

As bandwidth constraints on LAN/WAN environments decrease, the demand for distributed services will continue to increase. In particular, the proliferation of user-level applications requiring high-capacity distributed file storage systems will demand that such services be universally available. At the same time, the advent of high-speed networks have made the deployment of application and communication solutions based upon an Intelligent Mobile Agent (IMA) framework practical. Agents have proven to present an ideal development paradigm for the creation of autonomous large-scale distributed systems, and an agent-based communication scheme would facilitate the creation of independently administered distributed file services. This thesis thus outlines an architecture for such a distributed file system based upon an IMA communication framework.

Streszczenie:

The demand for Internet-based visual content delivery has increased significantly in recent years, triggered mainly by the widespread use of Internet enabled smartphones and portable devices, and by the availability of super HD content.As a consequence, live and on-demand video content has become the most important source of network traffic in mobile and fixed networks alike.In order to be able to efficiently deliver the increasing amount of video traffic, network operators have started to deploy caches and operator-owned CDNs. These solutions do not only reduce the amount of transit traffic of the operators but they may also improve the customers' quality of experience, through bringing the video content closer to customers. Nevertheless, their efficiency is determined by the algorithms and protocols used to allocate resources, both in terms of storage and bandwidth. The work in this thesis addresses the allocation of these two resources for operator-owned content management systems. In the first part of the thesis we consider a cache maintained by a single network operator. We investigate how caching at a network operator affects the content distribution system as a whole, and consequently, the efficiency of content delivery. We propose a model of the decision process undertaken by a network operator that aims at optimizing the efficiency of a cache by actively managing its bandwidth. We design different algorithms that aim at approximating the optimal cache bandwidth allocation and we evaluate them through extensive simulations and experiments. We show that active cache bandwidth allocation can significantly increase traffic savings. We then consider the potential interaction among caches maintained by different network operators.We consider the problem of selfish replication on a graph as a modelof network operators that individually deploy replication systems, and try to leverage their peering agreements so as to minimize the traffic through their transit providers. We use game-theoretical tools to investigate the existence of stable and efficient allocations of content at the network operators. We show that selfish myopic updates of content allocations at different network operators lead the system to a stable state, and that the convergence speed depends on the underlying network topology. In addition, we show that interacting operator-owned caches can reach a stable content allocation without coordination, but coordination leads to more cost efficient content allocations.<br><p>QC 20140401</p>

Streszczenie:

Les systèmes de stockage actuels font face à une explosion des données à gérer. A l'échelle actuelle, il serait illusoire d'imaginer une unique entité centralisée capable de stocker et de restituer les données de tous ses utilisateurs. Bien que du point de vue de l'utilisateur, le système de stockage apparaît tel un unique interlocuteur, son architecture sous-jacente est nécessairement devenue distribuée. En d'autres termes, le stockage n'est plus assigné à un équipement centralisé, mais est maintenant distribué parmi de multiples entités de stockage indépendantes, connectées via un réseau. Par conséquent, la bande passante inhérente à ce réseau devient une ressource à prendre en compte dans le design d'un système de stockage distribué. En effet, la bande passante d'un système est intrinsèquement une ressource limitée, qui doit être convenablement gérée de manière à éviter toute congestion du système. Cette thèse se propose d'optimiser l'utilisation de la bande passante dans les systèmes de stockage distribués, en limitant l'impact du churn et des défaillances. L'objectif est double, le but est d'une part, de maximiser la bande passante disponible pour les échanges de données, et d'une autre part de réduire la consommation de bande passante inhérente aux opérations de maintenance. Pour ce faire, nous présentons trois contributions distinctes. La première contribution présente une architecture pair-à-pair hybride qui tient compte de la topologie bas-niveau du réseau, c'est à dire la présence de gateways entre les utilisateurs et le système. La seconde contribution propose un mécanisme de timeout adaptatif au niveau utilisateur, basé sur une approche Bayésienne. La troisième contribution décrit un protocole permettant la réparation efficace de données encodées via des codes à effacement. Enfin, cette thèse se conclut sur la possibilité d'utiliser des techniques d'alignement d'interférence, communément utilisées en communication numérique afin d'accroître l'efficacité des protocoles de réparation de données encodées.

碩士<br>國立清華大學<br>資訊系統與應用研究所<br>104<br>Due to the elasticity and convenience of usage, cloud storage systems have played an important role in the market of data storage. However, as user data are stored on cloud storage systems hosted by cloud service providers, their privacy against unauthorized accesses becomes a critical concern. In the meantime, it is an interesting and important issue on how to consolidate multiple heterogeneous cloud storage systems as one virtual storage space, so as to fully utilize the storage space and access bandwidth of the cloud storage systems. There are still some missing parts in the joint optimization of storage space and access bandwidth for a high-performance, economical virtual storage system. This work proposes a novel scheme for the storage arbiter, which performs the storage consolidation and various data management tasks, such as the data placement, migration, and indexing. The storage arbiter could be hosted on a private server or a secure cloud service, so as to ensure the privacy of user data. In addition, we present a window-based technique for hot data identification to support the data management tasks, such as data migration. To evaluate the presented scheme and technique, we used trace-driven simulation on real-world workloads, where the experimental results are very encouraging.

Leave management system plays a major role in payroll system. A system which helps in recording, managing, and tracking employees leave requests. The existing system is a web-based solution built on .NET and Oracle Database. Although the interface is compatible for personal computers, laptops, and mobile devices, it does not provide a better user-friendly experience for mobile users and doesn’t necessarily provide faster access to leave related transactions as it needs better network bandwidth. This raised the need for a mobile application which empowers the user with ability to request and accept leaves on-the-go with the simple, user-friendly application design with limited network bandwidth. The main aim of the project is to develop an android application which contributes to the existing leave management web interface of the payroll system. Objectives of the expected android application are:To develop an application which provides better User Experience To design efficient User Interface which increases the performance of the application process while ensuring efficient usage of memory and reduce heavy usage of resources such as processing power and storage Deliver a completely automated, self-reliant application which can work seamlessly with the existing web application without causing any interoperability issues.

Streszczenie:

Today, cloud computing is the most emerging technology, as one can store and manage huge amounts of data. Data stored in cloud storage is becoming a more attractive trend. Therefore, such a type of data storage system sometimes stores the same kind of data for different users. Hence Carbon copies of data waste cloud storage space, and it is an incapable task. Nowadays, data deduplication is one of the technologies in cloud storage, according to current market trends, that avoids such data duplication caused by privileged as well as non-privileged users. It enables companies and organisations to save a huge amount of money on data storage and on bandwidth to transact data when derivatives are offsite for disaster recovery. To execute these desires, secure de-duplication and integrity auditing delegation methodologies have been studied, which can lessen the quantity of statistics stored with the aid of removing duplicate copies and permit customers to successfully verify the integrity of saved documents via delegating highpriced operations to a trusted person, respectively. In our schema, users do not need to be online to do extra computation while recording popularity adjustments, thereby lowering the need for needless antique information from the cloud. The cloud can carry out the venture of confirmation alternate to make certain that the cloud storage auditing still runs fluently and the proposed scheme is safe and efficient

Streszczenie:

Recent years have witnessed a great technological evolution in video display and capturing technologies leading to the development of new standards of video coding including MPEG-X, H.26X and HEVC. The cost of computations, storage and high bandwidth requirements makes a video data expensive in terms of transmission and storage. This makes video compression absolutely necessary prior to its transmission in order to accommodate for different transmission media's capabilities. Digital video compression technologies therefore have become an important part of the way we create, present, communicate and use visual information. The main aim behind a video compression system is to eliminate the redundancies from a raw video signal. The tradeoff involved in the process of video compression is between the speed, quality and resource utilization. The current chapter explores the techniques, challenges, issues and problems in video compression in detail along with the major advancements in the field.

Streszczenie:

With the further development of the internet of everything, as well as the increasing number of smart phones, smart glasses, and other end devices, the data growth rate has far exceeded the growth rate of network bandwidth. Meanwhile, the appearance of numerous novel applications, such as augmented reality (AR) and driverless technology, has higher demand for network latency. Therefore, edge computing integrates computing, network, and storage resources into a unified platform, which offers services to users, so that the data can be effectively processed at the beginning. This model is different from cloud computing that transmits all the data to a data center. It bypasses the bottleneck of network bandwidth and delaying and has aroused widespread concern. At the beginning, this article introduces the concept of edge computing and presents the definition of edge computing; then, it introduces the basic concept, characteristics and demands of smart water; at last, it constructs a smart water system framework on the basis of edge computing, and conducts functional analysis on each layer of the framework.

Streszczenie:

Volume holographic architectures in the form of rotating disks [1] or stationary volumes [2] have been demonstrated for data storage. Recently, thin film materials have been developed that are inexpensive, easy to manufacture, can be applied to large glass substrates, and have relativily large dynamic range. An example of such a material is DuPont’s HRF-150 photopolymer [3,4]. A holographic storage system’s density is limited by two parameters – the system’s bandwidth (either temporal or spatial frequency) and the material’s dynamic range. Because of their relativily large dynamic range and limited thickness, the storage density of thin films is limited primarily by the required system bandwidth. This paper describes a method of multiplexing holograms that alleviates the bandwidth limited density problem, and therefore, significantly increases the storage density of thin films.

Streszczenie:

Maintaining the accumulator pressure regardless of its energy level and tracking the power demanded by the electrical grid are two potential advantages of the Compressed Air Energy Storage (CAES) system proposed in [1, 2]. In order to achieve these goals, a nonlinear controller is designed motivated by an energy-based Lyapunov function. The control inputs of the storage system include displacement of the pump/motor in the hydraulic transformer and displacement of the liquid piston air compressor/expander. While the latter has a relatively low bandwidth, the former is a faster actuator with a higher bandwidth. In addition, the pneumatic path of the storage vessel that is connected to the liquid piston air compressor/expander has a high energy density, whereas the hydraulic path of the storage vessel is power dense. The nonlinear controller is then modified to achieve a better performance for the entire system according to these properties. In the proposed approach, the control effort is distributed between the two pump/motors based on their bandwidths: the hydraulic transformer reacts to high frequency events, while the liquid piston air compressor/expander performs a steady storage/regeneration task. As a result, the liquid piston air compressor/expander will loosely maintain the accumulator pressure ratio and the pump/motor in the hydraulic transformer will precisely track the desired generator power. This control scheme also allows the accumulator to function as a damper in the storage system by absorbing power disturbances from the hydraulic path generated by wind gusts.

In the realm of hard disk drives (HDD), dual-stage servo control has been shown to achieve increased control bandwidth and reduced power consumption compared to single-stage architectures [1]–[4]. Motivated by these results, we seek to apply dual-stage control to an analogous case of an optical pointing system, which has similar objectives of high-bandwidth control over a wide spatial range.

Streszczenie:

As part of the U.S. Navy’s continued commitment to protecting U.S. interests at home and abroad, the Navy is investing in the development of new technologies that broaden U.S. warship capabilities and maintain U.S. naval superiority. In particular, NAVSEA is supporting the development of power systems technologies that help the Navy realize an all-electric warship. It is recognized that a challenge to fielding an all-electric power system architecture includes minimizing the size of energy storage systems while maintaining the response times necessary to support potential pulsed loads. This work explores the trade-off between energy storage requirements (i.e. size and weight) and performance (i.e. bandwidth and storage) in the context of a power system architecture that meets the needs of the US Navy. To compare energy storage technologies and appropriately size them, it is necessary to specify size and weight requirements and thus consider the energy density of the technology in Wh/kg and specific power density in W/kg. The modelled time domain behaviour for different load types and control delays were used to determine technology and sizing requirements by comparing the total energy and maximum power used in the simulation to a Ragone plot. Simulation results based on operational vignettes were used to identify a range of specific power and energy densities that will meet system requirements. Potential energy storage sizing can be determined by approximating where a selected technology intersects with the energy and power requirements of the system. Another major component necessary to determine energy storage technology is the frequency domain behaviour of the system. In this work, the energy storage control bandwidth is evaluated in simulation for different loading scenarios, and a trade-off between size/weight and response bandwidth is illustrated.

The bandwidth of high definition television signal is too wide to record the signal on the disc for a long time. Adopting the MUSE (Multiple Sub-Nyquist Sampling Encording) signal, which is band-width compressed to about 8 MHz, to solve the ploblem, we had developed an HDTV videodisc of 30 minutes per side and player for the profesional use. However, in order to introduce MUSE videodisc to consumer market in the future, the playback time per side is required to be at least 60 min. To realize a playback time of 60 minutes, the authors have developed disc recording system and playback system which handle the high density videodisc.

<div class="section abstract"><div class="htmlview paragraph">With the increased use of devices requiring the Internet of Things (IoT) to enable “New Mobility,” the demand for satellite-enabled IoT is growing steadily, owing to the extensive coverage provided by satellites (over existing ground-based infrastructure). Satellite-based IoT provides precise and real-time vehicle location and tracking services, large-scale geographical vehicle and/or infrastructure monitoring, and increased coverage for remote locations where it may not be possible to install ground-based solutions.</div><div class="htmlview paragraph"><b>The Application of Satellite-based Internet of Things for New Mobility</b> discusses satellite-based IoT topics that still need addressing, which can be broadly classifieds into two areas: (1) affordable technology and (2) network connectivity and data management. While recent innovations are driving down the cost of satellite-based IoT, it remains relatively expensive, and widespread adoption is still not as high as terrestrial, ground-based systems. Security concerns over data and privacy also create significant barriers to entry and need to be addressed along with issues such as intermittent connectivity, latency and bandwidth limitations, and data storage and processing restrictions.</div><div class="htmlview paragraph"><a href="https://www.sae.org/publications/edge-research-reports" target="_blank">Click here to access the full SAE EDGE</a><sup>TM</sup><a href="https://www.sae.org/publications/edge-research-reports" target="_blank"> Research Report portfolio.</a></div></div>
