Abstract:
SMAN 4 Magelang ialah salah satu sekolah yang membutuhkan internet sebagai salah satu media dalam mencari informasi, akan tetapi bandwidth yang dialokasikan untuk pengguna internet belum diatur dengan baik, sehingga bandwidth yang tersedia belum mampu memenuhi kebutuhan pengguna internet secara optimal. Selain itu, SMAN 4 Magelang memiliki perilaku aktifitas yang berbeda - beda dalam menggunakan internet. Aktivitas penggunaan internet tersebut diantaranya browsing, mailing, chatting, streaming, dan download. Penggunaan internet yang berbeda tersebut membutuhkan pengaturan dalam pembagian bandwith internet agar pengguna internet menerima alokasi bandwidth sesuai dengan kebutuhan penggunaan internet. Pengaturan bandwith untuk kebutuhan internet dilakukan dengan menggunakan Traffic Shapping yang mengatur bandwidth internet untuk pengguna internet sesuai dengan aktivitas penggunaan internet. Traffic Shapping PCQ memastikan bahwa setiap pengguna dalam satu jaringan mendapatkan bandwith yang sama dengan membatasi besar bandwidth per alamat IP pengguna internet sehingga tidak mempengaruhi kecepatan koneksi internet pengguna yang lain. Hasil penelitian ini dapat mengoptimalkan bandwidth internet untuk memenuhi kebutuhan pengguna internet di SMAN 4 Magelang.

Abstract:
Sejalan dengan kemajuan dan pengembangan Teknologi Informasi dan Komunikasi (TIK) terutama dalam bidang jaringan komputer maka menuntut lembaga pendidikan terutama sekolah, yakni SMK YPM 7 Tarik dalam membangun sebuah Laboratorium TIK yang dilengkapi dengan internet agar dapat diakses oleh guru dan siswa untuk mendapat informasi yang update, cepat dan akurat. Akan tetapi kebebasan dalam memakai internet untuk download dan upload di laboratorium terkadang digunakan siswa untuk hal-hal yang kurang berguna dalam lingkungan pendidikan misalnya men-download film atau lagu. Untuk mengatasi hal tersebut maka diperlukan suatu sistem mangement bandwidth untuk mengatur pemakaian bandwidth di tiap-tiap user laboratorium agar penggunaan bandwidth dapat optimal sesuai dengan porsi dan kebutuhan masing-masing client dengan pembatasan download maupun upload. Salah satu perangkat yang dapat memanajemen bandwidth adalah Router. Personal komputer (PC) router berbasis mikrotik merupakan alternatif untuk menekan biaya pembelian router pabrikan yang harganya masih mahal. Mikrotik sebagai sistem operasi karena memiliki beberapa kelebihan, yaitu lisensinya murah, tidak membutuhkan spesifikasi hardware yang besar, instalasi tidak rumit dan administrasinya mudah.

Abstract:
In distributed data storage, a particular dataset can reside at multiple locations in order to get high availability .Thus, the dataset can be downloaded in parallel from multiple nodes.Throughput between server and client changes dynamically, so the downloading speed can vary unpredictably. A dynamic parallel downloading algorithm based on measurement of bandwidth and bandwidth prediction is produced in this paper and server caching is adopted in order to improve downloading speed. The algorithm dynamically adjusts downloading of the last block to make parallel downloading from multiple servers end almost simultaneously. With this approach, the download time is reduced and the robustness of the downloading system is improved. Besides, the algorithm not only avoids complicated server selecting mechanism, but also improves load balance of the servers.

Abstract:
Peer-to-peer (P2P) systems are becoming a popular means of streaming audio and video content but they are prone to bandwidth starvation if selfish peers do not contribute bandwidth to other peers. We prove that an incentive mechanism can be created for a live streaming P2P protocol while preserving the asymptotic properties of randomized gossip-based streaming. In order to show the utility of our result, we adapt a distributed incentive scheme from P2P file storage literature to the live streaming scenario. We provide simulation results that confirm the ability to achieve a constant download rate (in time, per peer) that is needed for streaming applications on peers. The incentive scheme fairly differentiates peers' download rates according to the amount of useful bandwidth they contribute back to the P2P system, thus creating a powerful quality-of-service incentive for peers to contribute bandwidth to other peers. We propose a functional architecture and protocol format for a gossip-based streaming system with incentive mechanisms, and present evaluation data from a real implementation of a P2P streaming application.

Abstract:
Internet is one of the needs of the community, especially among education and academics such as universities. The high level of internet users is not comparable with the facilities owned by an agency, this makes the internet network manager in Higher Education feel difficult. The cause of the problem that is always a problem is the speed and internet connection is always disjointed, resulting in the slow loading process data while browsing, both at the time of download and at the time of upload. To make internet users in campus area balanced and stable then need bandwidth management based on traffic usage of internet path better. Bandwidth management that can stabilize traffic lanes and equal bandwidth distribution, it can use bandwidth management by Hierarchical Token Bucket (HTB) method. The calculation result in HTB method testing through file download, the average value obtained by TIPHON category standard for throughtput value index is 2 with "Medium" category, delay parameter index is 4 with "Very Good" category, jitter parameter index is 3 with the "Good" category and the packet loss parameter index is 4 with the "Very Good" category.

For modern scientific applications such as astrophysics, astronomy, aerography, and biology, a large amount of storage space is required because of the large-scale datasets. Data Grid collects distributed storage resources such as hard disk space across heterogeneous networks to meet such requirements. In data grid environment, data replication service that copies the replicas to proper storage systems increases the reliability of the data access. By means of these replicas, parallel download creates multiple connections from the client side to the replica servers to improve the performance of the data transfer. During a large dataset transferring, the dynamic network status and different states of the replica servers make the transferring time hard to predict. If the available bandwidths of some replica servers become lower during the downloading progress, the completion time will be increased. Therefore, to adapt the bandwidth-variation and to make the data transferring more efficient, a parallel download scheme which is called EA (Efficient and Adaptive) parallel download is proposed in this thesis. The scheme is to re-evaluate all of the replica servers during the download progress and replace the decaying selected servers with better backup servers. According to our experiments in the Unigrid environment, the EA parallel download decreases the completion time by 1.63% to 13.45% in natural Unigrid environment and 6.28% to 30.56% in choreographed Unigrid environment when compared to the Recursive Co-Allocation scheme. It means that the proposed scheme adapts to the dynamic environment nicely and decreases the total download time effectively.

In early stages of the Internet, the client-server model is used to obtain information. As the number of users increases, the server has to serve much more requests. Traditional client-server model is inadequate to use, so the P2P architecture emerged mainly relying online peers to share files to each other. However, some peers will leave the system immediately when they finish download, which results in the reduction of the number of online peers, as well as the upload bandwidth of the system.This phenomenon is called free-riding. In the BitTorrent system, if the high-bandwidth peers leave the system and provide no more services when they finish downloading, the low-bandwidth peers can only rely on the server or the other low-bandwidth peers to obtain pieces, which slows down the download speed. To improve the situation, we proposed the Delaying Completion of Fast Peers (DCFP) strategy, whose objective is to keep the high-bandwidth peers online as long as possible, such that let the low-bandwidth peers can download the pieces steadily. In our simulation we assume that a peer will leave the system as soon as it finishes downloading. Simulation results show that our DCFP strategy makes 7% to 28% improvement over BT in the average download time.

In face of a large file sharing need due to the rapid development of the Internet, Peer-to-peer (P2P) download has been the most viable solution. BitTorrent (BT) has been the widely used P2P protocol by now. Because the neighbors allocated to a newly-joined node by the tracker are randomly selected, these neighbors could be located in networks at a distance. The transmission may incur a large amount of cross-network traffic, resulting in increased download time. Another problem is that when a node finishes downloading the file, it might leave the system right away instead of staying online to share its resources. This free-riding phenomenon also reduces the quality and stability of the system. In this paper, we propose a service algorithm called Bandwidth and Piece Demand (BWPD) that considers both the effective transmission bandwidth and the total demand of the neighbors for a target file piece. Our algorithm first gives priority to high-bandwidth nodes with high total demand. After these nodes retrieve most of the pieces, we then reduce their priority to force them stay in the system to help other nodes download the file pieces. This strategy can increase the overall download speed of the nodes, thus reducing the average download time. Simulation results show that our BWPD algorithm can produce an eleven to eighteen percent reduction over BT on the average download time.

Abstract:
Uncompressed multimedia data such as images require huge storage space, processing power, transmission time, and bandwidth. In order to reduce the storage space, transmission time, and bandwidth, the uncompressed image data is compressed before its storage or transmission. This process not only permits a large number of images to be stored in a specified amount of storage space but also reduces the time required for them to be sent or download from the internet. In this chapter, the classification of an image on the basis of number of bits used to represent each pixel of the digital image and different types of image redundancies is presented. This chapter also introduced image compression and its classification into different lossless and lossy compression techniques along with their advantages and disadvantages. Further, discrete cosine transform, its properties, and the application of discrete cosine transform-based image compression method (i.e., JPEG compression model) along with its limitations are also discussed in detail.

Abstract:
Access networks are usually termed “last-mile/first-mile” networks since they connect the end user with the metro-edge network (or the exchange). This connectivity is often at data rates that are significantly slower than the data rates available at metro and core networks. Metro networks span large cities and core networks connect cities or bigger regions together by forming a backbone network on which traffic from an entire city is transported. With the industry achieving up to 400 Gbps of data rates at core networks (and increasing those rates [Reading, 2013]), it is critical to have high-speed access networks that can cope with the tremendous bandwidth opportunity and not act as a bottleneck. The opportunity lies in enabling services that can be of benefit to the consumers as well as large organizations. For instance, moving institutional/personal data to the cloud will require a high-speed access network that can overcome delays incurred during upload and download of information. Cloud-based services, such as computing and storage services are further enhanced with the availability of such high-speed access networks. Access networks have evolved over time and the industry is constantly looking for ways to improve their capacity. Therefore, an understanding of the fundamental technologies involved in wired and wireless access networks will help the reader appreciate the full potential of the cloud and cloud access. Against the same backdrop, this chapter aims at providing an understanding of the evolution of access technologies that enable the tremendous mobility potential of cloud-based services in the contemporary cloud paradigm.

Abstract:
Mobile multimedia has been promoted as a promising service and application in mobile e-commerce (m-commerce) by many mobile operators and mobile service providers, when high-speed mobile networks are expected to take off in the near future. However, at present, mobile multimedia is still in its infancy, accessed by relatively low-end mobile devices with limited bandwidth and resources. A typical example is Orange in Hong Kong which launched a low-grade multimedia service in 2000 to test the market with current mobile technologies. Due to the physical constraints of a 2.5G mobile network, audio broadcast is the best service that the network can offer up to date. However, in the near future, when advanced mobile networks and technologies become available, higher demands will be placed on the quality of mobile multimedia services. Such services support both audio and video data, for example, video conferencing, music video, video-on-demand and so on. Rights management deserves more serious concern because intellectual property of distributed multimedia content is as valuable as a company’s physical assets (Doherty, 2002). This will become even more important when mobile multimedia services become marketable and an essential part of the business. The purpose of a digital rights management (DRM) system is to allow owners of digital assets (movies, songs) to distribute their products/services/contents electronically in a controlled way (Peinado, 2002). DRM technology makes various online payment schemes possible, such as pay-per-view, pay-per-download, pay-per-game and so on. Hence, mobile service providers are able to control end users’ use of, and accessibility to, their products, and stand to gain huge profits from this capability with the DRM technology (Foroughi, Albin, & Gillard, 2002). A successful DRM system should address both business and technical issues (Grab, 2002), but this chapter only addresses and presents issues in the technical side due to the nature of this book. We present some critical issues of mobile DRM for mobile multimedia. A proposal of mobile DRM framework is presented to meet the urgent DRM needs with the existing 2.5G mobile technology. This chapter is concluded by presenting future directions of mobile DRM for mobile multimedia.

Abstract:
With the huge number of information sources available on the Internet and the high dynamics of their data, peer-to-peer (P2P) systems propose a communication model in which each party has the same capabilities and can initiate a communication session. These networks allow a group of computer users with the same networking program to connect with each other and directly access resources from one another. P2P architectures also provide a good infrastructure for data and computer intensive operations such as data mining. In this article we consider a new data mining approach for improving resource searching in a dynamic and distributed database such as an unstructured P2P system, that is, in Masseglia, Poncelet, and Teisseire (2006) we call this problem P2P usage analysis. More precisely we aim at discovering frequent behaviors among users of such a system. We will focus on the sequential order between actions performed on each node (requests or downloads) and show how this order has to be taken into account for extracting useful knowledge. For instance, it may be discovered, in a P2P file sharing network that for 77% of nodes from which a request is sent for “Mandriva Linux,” the file “Mandriva Linux 2005 CD1 i585-Limited- Edition-Mini.iso” is chosen and downloaded; then a new request is performed with the possible name of the remaining iso images (i.e., “Mandriva Linux 2005 Limited Edition”), and in the large number of returned results the image corresponding to “Mandriva Linux 2005 CD2 i585-Limited-Edition-Mini.iso” is chosen and downloaded. Such knowledge is very useful for proposing the user with often downloaded or requested files according to a majority of behaviors. It could also be useful in order to avoid extra bandwidth consumption, which is the main cost of P2P queries (Ng, Chu, Rao, Sripanidkulchai, & Zhang, 2003).

Abstract:
Recent years have witnessed the rapid progress in handheld devices. This has resulted in a growing number of mobile phones or PDAs that have a built-in camera to record still pictures or live videos. Encouraged by the success of second generation cellular wireless networks, researchers are now pushing the 3G standard to support a seamless integration of multimedia data services. One of the main products is WCDMA (Holma & Toskala, 2001), short for wideband code division multiple access. WCDMA networks have 80 million subscribers in 46 countries at the time of this writing. WCDMA can be viewed as a successor of the 2G CDMA system. In fact, many WCDMA technologies can be traced back to the 2G CDMA system. However, WCDMA air interface is specifically designed with envision to support real time multimedia services. To name some highlights, WCDMA: • Supports both packet-switched and circuitswitched data services. Mobile best-effort data services, such as Web surfing and file downloads, are available through packet service. • Has more bandwidth allocated for downlink and uplink than the 2G systems. It uses a 5 MHz wide radio signal and a chip rate of 3.84 mcps, which is about three times higher than CDMA2000. • Support a downlink data rate of 384 kbps for wide area coverage and up to 2 Mbps for hot-spot areas, which is sufficient for most existing packet-data applications. WCDMA Release 5 (Erricson, 2004) adopts HSDPA (High-speed downlink packet access), which increases peak data rates to 14 Mbps in the downlink. To achieve high data rate, WCDMA uses several new radio interface technologies, including (1) shared channel transmission, (2) higher-order modulation, (3) fast link adaptation, (4) fast scheduling, and (5) hybrid automatic-repeat-request (HARQ). These technologies have been successfully used in the downlink HSDPA, and will be used in upcoming improved uplink radio interface in the future. The rest of this article will explain the key components of the radio interface in WCDMA.

Abstract:
Abstract Autonomous Underwater Vehicle (AUV) missions are limited in range and duration by the vehicle’s battery capacity, and sensor payloads are limited by the processing power onboard which is also restricted by the vehicle’s battery capacity. Furthermore, the power consumption of a vehicle’s acoustic system limits the possibility of substantial data transmission, requiring the AUV be retrieved to download most data. The Platform for Expanding AUV exploRation to Longer ranges (PEARL), described in this paper, aims to extend the range and endurance of AUVs while reducing data latency and operating costs. PEARL is an integrated autonomous floating servicing station that utilizes renewable energy to simultaneously provide AUV battery recharging and data uplink via new generation high-bandwidth low-Earth orbit satellite constellations. This paper details the design and testing of two potential AUV docking modules of the PEARL system. The modules are uniquely located near the ocean surface, an energetic environment that presents a particular set of challenges for AUV docking. The results will be used to inform the design of a prototype system to be tested in an ocean setting.

Abstract:
This paper introduces a simple approach utilizing MATLAB® computational tools for generating rational polynomial transfer functions for fluid transients in both liquid and gas fluid transmission lines. These transfer functions are obtained by curve fitting in the frequency domain the exact solution to the distributed parameter laminar flow “Dissipative Model” for fluid transients that includes nonlinear frequency dependent viscous friction terms as well as heat transfer effects in gas lines. These transfer functions are formulated so they are applicable to arbitrary line terminations and so they can be inserted directly into SIMULINK® models for time domain simulation and analysis of a total system of which the fluid lines are only internal components. The inputs to the algorithm are the internal radius and length of the line; the kinematic viscosity, density, Prandtl number, and speed of sound of the fluid; and the maximum frequency to which an accurate curve fit of the exact solution is desired. This maximum frequency normally is equal to or greater than the bandwidth of the other components in the total system to be analyzed or the maximum frequency associated with the input. The simplicity of use and accuracy in the results of the exact solution representations are demonstrated for examples of a blocked fluid line and of a line terminating into a tank. The computational algorithms are available for download from the Author’s web site. This is the first of two papers pertaining to transfer functions for fluid transients. The second paper pertains to formulating simulation diagrams for total systems containing fluid lines represented by rational polynomial transfer functions.

Abstract:
medical application running outside the workstation environment has to deal with several limitations, such as reduced available memory and low network bandwidth. Adaptations and novel approaches are required to make applications overcome such problems. This paper presents an approach that uses a combination of client- and server-side procedures to dynamically optimize the data flow for fast image transfer and visualization on mobile and stationary devices. The main goal of our approach is to minimize the amount of data transferred to and used in the host device without sacrificing the user experience. Our approach was implemented and validated using a real use case, the application Animati Viewer, which is a web visualizer for diagnostic images. The evaluation was measured using metrics such as the accumulated amount of network transferred data and the amount of memory used in the host device. The results show that our approach is feasible and, in one of our tests, it transferred only 7.73% of the amount of data downloaded by the OsiriX mobile.
