whitepaper Nott Company Gets Flexible With MPLS2007-06-04 New Edge Networks
  Nott Company is a leading supplier of fluid power systems, industrial power transmission products and custom rubber fabrication. The company wanted to provide multiple locations with reliable and cost-effective, high-speed network access and ATM over DSL network which lacked the flexibility to accommodate growth. The challenge was to get additional bandwidth and QoS for future applications and slow technical support from major network vendors. Nott Company deployed New Edge Networks for its solution and implemented MPLS network and Managed Network Services (MNS).

whitepaper Managing Network Bandwidth to Maximize Performance2007-06-01 Fluke Networks
  With increasing bandwidth demands, network professionals are constantly looking to optimize network resources, ensure adequate bandwidth, and deliver high performance. Often, buying more bandwidth is not a priority or an option due to limited budgets and pressure to reduce IT costs. This white paper describes how to leverage best practices to monitor, baseline, and manage the network bandwidth and performance. It also highlights how to identify and eliminate issues such as unwanted traffic, unwanted protocols, and network problems with factory default switch configurations.

whitepaper Self-Similar Properties Under the Bandwidth Restrainment2007-06-01 Tokai University
  The scale-invariant burstiness or self-similarity has been found in real networks. Relation between self-similarity and networks and/or system parameter is the center of discussion in the context of application layer. This self-similarity is caused by the file size of Web servers or the duration of user sessions. In addition, self-similar burstiness has been characterized by the transport layer protocol. Traffic dynamics, however, are mainly generated by physical conditions such as the resource restrainment. This paper has investigated the property of self-similar traffic under the resource restrainment to make the network parameter vary using the network simulator. The main finding in analyzing the simulated results is that self-similar property is more sensitive to packet loss rate than to throughput.

whitepaper AMD Opteron Processors Deliver Outstanding Performance for Telecommunications Business Support Systems (BSS)2007-05-30 Advanced Micro Devices (AMD)
  Increasing challenges in billing systems demand reliable and scalable standard computing server technology with increasing performance to handle the increasing complexity and number of subscriber, service, and pricing data. COMARCH has tested a Dual-Core AMD Opteron processor-based server with its Billing System. Wherever there is a need for processing of large amounts of data such as rating of telecommunications subscriber usage data or generating detailed invoices for millions of subscribers, Dual-Core AMD Opteron processors can be relied upon to deliver outstanding performance resulting in the processing of more billing requests at a time with lower power consumption and space requirements, providing higher efficiency to communication service providers.

whitepaper High-Bandwidth Address Generation Unit2007-05-28 Delft University of Technology
  This paper describes an efficient data fetch circuitry for retrieving several operands from a n-bank interleaved memory system in a single machine cycle. The proposed Address GENeration (AGEN) unit operates with a modified version of the low-order-interleaved memory access approach. The design supports data structures with arbitrary lengths and different (odd) strides. A detailed discussion of the 32-bit AGEN design aimed at multiple-operand functional units is presented. The experimental results indicate that the AGEN is capable of producing 8 x 32-bit addresses every 6 ns for different stride cases when implemented on VIRTEX-II PRO xc2vp30-7 1696 FPGA device using trivial hardware resources.   
whitepaper Delay Tolerant Applications for Low Bandwidth and Intermittently Connected Users: The aAQUA Experience2007-05-12 Indian Institute of Technology Bombay
  With the explosive growth and spread of Internet, web access from mobile and rural users has become significant. But these users face problems of low bandwidth and intermittent Internet connectivity. To make the benefits of the Internet reach the common man in developing countries, accessibility and availability of the information has to be improved. aAQUA is an online multilingual, multimedia agricultural portal for disseminating information from and to rural communities. Considering resource constrained rural environments, this paper has designed and implemented an offline solution which provides an online experience to users in disconnected mode. The solution is based on heterogeneous database synchronization which involves only a small synchronization payload ensuring an efficient use of available bandwidth.   
whitepaper Bandwidth-Efficient Geographic Multicast Routing Protocol for Wireless Sensor Networks2007-05-01 Institute of Electrical and Electronics Engineers
  This paper presents Geographic Multicast Routing (GMR), a new multicast routing protocol for wireless sensor networks. It is a fully localized algorithm that efficiently delivers multicast data messages to multiple destinations. It does not require any type of flooding throughout the network. Each node propagating a multicast data message needs to select a subset of its neighbors as relay nodes towards destinations. GMR optimizes the cost over progress ratio where the cost is equal to the number of neighbors selected for relaying and the progress is the overall reduction of the remaining distances to destinations.

whitepaper Variable Bandwidth Image Denoising Using Image-Based Noise Models2007-04-27 DxO Labs
  This paper introduces a variational formulation for image denoising based on a quadratic function over kernels of variable bandwidth. These kernels are scale adaptive and reflect spatial and photometric similarities between pixels. The bandwidth of the kernels is observation-dependent to-wards improving the accuracy of the reconstruction process and is constrained to be locally smooth. The paper analyzes the evolution of the noise model form the RAW space to the RGB one, by propagating it over the image formation process. The experimental results demonstrate that the use of a variable bandwidth approach and an image intensity dependent noise variance ensures better restoration quality.   
whitepaper Scalable Application-Specific Measurement Framework for High Performance Network Video2007-04-24 Association for Computing Machinery
  Extensive studies show that bandwidth provisioning is the key method to guarantee the performance of mission-critical real-time network applications. Unfortunately, network congestions, rate-limiting for special addresses and ports, and even the bad cabling may result in the bandwidth bottleneck along the end-to-end path. This is the main cause of degradation of the application performance, especially for the high-performance video applications which consumes large-bandwidth. The experiences, being both as a national academic Internet Service Provider and end-user of high-performance video applications, clearly indicate that using suitable measurement tools are critical to find the network bottlenecks and enable a successful video session.

whitepaper Evolution Towards Volume Deployable 40-Gbps Networks2007-04-23 Nortel Networks
  Despite the slowdown in the deployment of telecommunication equipment in the early 2000s, the demand for bandwidth hasn't stopped increasing. The explosion of video traffic has dictated new requirements on the network, which for a long time has been carrying voice traffic. This paper discusses the different options available to service providers and network operators to evolve today's 10-Gbps based transport network to higher capacity and highlights the key considerations, pros and cons of each option.
