whitepaper Packet Processing With Intel Multi-Core Processors: General Purpose Processor Exceeds Network Processor Performance2008-06-01 Intel
  In fewer than ten years from now, industry experts are forecasting network capacity demands will grow by a factor of one thousand1. Preparing for this data and bandwidth boom, service providers are looking for cost-effective equipment that is more flexible and scalable. This white paper focuses on consolidating control and data processing on general purpose multicore processors. It describes methods to optimize packet processing software and enable network elements to attain compelling performance running on embedded Intel architecture-based platforms. Benchmark data is also provided for two prototypes, a radio network controller (RNC) and standard packet processing, running on a single board based with Quad-Core Intel Xeon processors.

whitepaper Anticipating the Bandwidth Bottleneck: Meeting Future Bandwidth Demands2008-06-01 Motorola
  Living today in a media-crazed world, where individuals create, consume, and share media in ways never before imagined. And these consumers are not just demanding more media. Due to multitasking, they're packing more media consumption into smaller slices of time, significantly increasing the amount of bandwidth needed to support individual viewing habits. This increased bandwidth consumption is compounded by the fact that a growing portion of U.S. households with multiple PCs and TVs routinely receive multiple media streams on multiple devices thanks to new features such as picture-in-picture (PIP), video over the Internet, and Digital Video Recording. This ever-increasing consumption of content will continue to require unprecedented amounts of bandwidth.

whitepaper Deploying Ethernet Access for Business Services2008-06-01 Cisco Systems
  The leading provider of telecommunications services in Switzerland, Swisscom wanted to stay ahead of the competition with best-in-market business services and enable more bandwidth for video and other services demanded by corporate customers. The challenge was to simplify the infrastructure to keep operating costs low and enable more flexible service delivery. Recognizing the need to converge networks in the future, Swisscom made the decision to build a single Carrier Ethernet infrastructure that could simultaneously deliver both Layer 2 and Layer 3 Ethernet services with customer-managed or Swisscom-managed Customer Premise Equipment (CPE). Swisscom chose Cisco core, access, and aggregation solutions.

whitepaper Flight Evaluation of Adaptive High-Bandwidth Control Methods for Unmanned Helicopters2008-05-29 American Institute of Aeronautics and Astronautics
  This paper summarizes design of a high-bandwidth nonlinear adaptive attitude command system for an unmanned helicopter test bed, and presents an evaluation of the controller in both nonlinear simulation and flight test. The attitude command system features a dynamic inversion control law augmented by an on-line neural network. The design is cast in an output feedback setting. The inverting control law is based on a simple linear model of the helicopter and its actuators at the hover condition. An error observer-based method for output feedback design uses either a proportional plus derivative, or a proportional, integral and derivative form for the linear compensator.

whitepaper Bandwidth Consumption Control and Service Differentiation for Video Streaming2008-05-19 Electronics and Telecommunications Research Institute
  Multimedia streaming is resource demanding. It may starve other applications such as file transfer sharing the network, for example, in a smart home. To address the problem, a fuzzy logic control to bound the bandwidth consumption of multimedia streams is applied. This paper also differentiates the video quality for streams with different levels of importance. The transmission rate control and service differentiation schemes are implemented and evaluated in the department network where a number of different applications may coexist at the same time. Performance evaluation results show that the video streaming system can support the specified bit rate bound and differentiate the service to efficiently utilize the limited bandwidth.

whitepaper Engineering Firm Improves Collaboration, Lowers Travel Costs, Boosts Bandwidth by 230 Percent Using F5 WANJet2008-05-14 F5 Networks
  Graef, Anhalt, Schloemer & Associates GASAI's great success had led to rapid growth and a subsequent strain on the company's Wide Area Network (WAN). All applications are housed in the central Milwaukie, Wisconsin, data center, with all Internet traffic routed over T1 lines through a Milwaukie-based proxy server. The GASAI IT staff realized that it had two options for improving its WAN bandwidth: purchase application acceleration appliances or increase the bandwidth in each branch office. In the end, the company selected the F5 WANJet WAN optimization appliance because of its core TDR and TCP optimization feature set and price.

whitepaper A Novel Coding Technique to Minimise the Transmission Bandwidth and Bit Error Rate in DPSK2008-05-01 JNT UNIVERSITY
  This paper proposes a novel coding technique that aims to reduce the Transmission Bandwidth (BT) and Bit Error Rate (BER) vis-a-vis Conventional Differential Phase Shift Keying (CDPSK) in digital band pass transmission. In CDPSK two successive bits are used for encoding. The proposed method encodes information with respect to the consecutive two bits b(t-Tb) and b(t-2Tb). The encoded data is keyed on to the phase. The received signal is demodulated by using the present phase ö(t) and the two phases ö(t-Tb) and ö(t-2Tb). Comparative analysis between the two techniques reveals the advantages of the proposed technique.

whitepaper Application Sensitivity to Link and Injection Bandwidth on a Cray XT4 System2008-05-01 Sandia National Laboratories
  This paper describes the efforts to characterize application sensitivity to link and injection bandwidth on a Cray XT4 system. Link bandwidth is controlled by modifying the number of rails activated per network link. Injection bandwidth is controlled by modifying the speed of the HyperTransport connection between the Opteron and the SeaStar. A suite of micro-benchmarks and applications is evaluated at several different operating points. The experimental techniques developed by this paper are expected to be useful for future architecture research.

whitepaper Advanced OTDR Analysis - Has Technology Made it a Lost Art?2008-04-23 Fluke Networks
  Is the ability to manually set up tests and interpret Optical Time Domain Reflectometer (OTDR) traces becoming a lost art, due to embedded processors and sophisticated software? This article discusses some of the advanced OTDR techniques that expert technicians use to perform during testing.

Similar to a digital photographer's film camera experience, an understanding of the knowledge and skills used for manual OTDR testing can enhance a technician's fiber testing when using the latest OTDR with automatic capabilities.

whitepaper ASMi-54 G.SHDSL.bis Modem Extends High-Speed Network Over Existing Infrastructure2008-04-22 RAD Data Communications
  Lattelecom, Latvia's leading provider of communications services and solutions, was selected as the integrator for a state-sponsored project to bring the Internet to public libraries throughout Latvia. The company wanted to use existing copper infrastructure to deliver high-speed data services. Lattelecom deployed RAD's ASMi-54 G.SHDSL.bis Ethernet modem which extends Ethernet over copper pairs, offering cost-effective delivery of high bandwidth to Last Mile customers.
