whitepaper Affordable HP Workstations Energize Engineers2008-11-01 Hewlett-Packard (HP)
  Burlington Electric Department, a municipal electric utility serves about 16,000 residential and 3,600 commercial customers in the City of Burlington, Vt. The company wanted to enable engineers to handle high-bandwidth, image-intensive applications at an affordable price-point. On recommendation of Ormsby's Computer Systems, Burlington Electric Department implemented high-powered HP xw4550 Workstations which provided faster data processing and file handling.

whitepaper TV White Space Position Paper: Fixed TV White Space Solutions for Wireless ISP Network Operators2008-11-01 Motorola
  Motorola is developing solutions for the TV White Space spectrum for both Service Providers as well as municipal state and local government entities. This paper specifically focuses on Motorola's fixed solution for broadband service providers operating networks predominantly in suburban and rural areas. This particular solution provides reliable point to multipoint fixed access to bandwidth that can be used for data transfer, voice and video applications from one fixed Access Point (AP) location to another fixed Subscriber Module (SM) location such as a business or residential structure.

whitepaper Available Bandwidth-Based Association in IEEE 802.11 Wireless LANs2008-10-31 Association for Computing Machinery
  The performance of an IEEE 802.11 station heavily depends on the selection of an AP (Access Point) that the station is associated with to access the Internet. The conventional approach to the AP selection is based on the received signal strength called RSSI (Received Signal Strength Indication) from APs within the transmission range. This approach however, might yield unbalanced traffic load among APs as the station chooses an AP only based on the signal strength, instead of considering the AP load and the level of contention on medium access. Accordingly, the station that is associated with the highest-RSSI AP might suffer from poor network performance.

whitepaper A Wide-Tracking Range Clock and Data Recovery Circuit2008-10-28 Institute of Electrical and Electronics Engineers
  SCALING of CMOS technology has progressed relentlessly for the past several decades and brought unprecedented benefits to digital Integrated Circuits (ICs). In order for the improvements of individual ICs to benefit the overall system, the performance of inter-chip communication circuits must also scale accordingly. To meet this growing demand for large Input - Output (IO) bandwidth, systems such as network switches and processor-memory interfaces employ hundreds of IO links to achieve an aggregate IO bandwidth in excess of 100 Gb/s. It consists of a transmitter, a channel, and a receiver. The transmitter sends the data to the receiver over a channel, typically a printed circuit board trace or a co-axial cable.

whitepaper On-Demand Webcast: IT As A Service2008-10-23 AT&T Intellectual Property
  The presenters of this webcast discuss the pros and cons of consuming IT resources and network bandwidth as an on-demand service. Benefits include a scalable infrastructure, usage-based pricing and more freedom to focus on the business. But there are more important things to consider - like reliability, security and performance - before deciding if IT as a service is right or not.

whitepaper Green WLANs: On-Demand WLAN Infrastructures2008-10-19 Intel
  Enterprise Wireless Local Area Networks (WLANs) that consist of a high-density of hundreds to thousands of Access Points (APs) are being deployed rapidly in corporate offices and university campuses. The primary purpose of these deployments is to satisfy user demands for high bandwidth, mobility, and reliability. However, the recent study of two such WLANs showed that these networks are rarely used at their peak capacity, and the majority of their resources are frequently idle. This paper brings to attention that a large fraction of idle WLAN resources results in significant energy losses. Thousands of WLANs world-wide collectively compound this problem, while raising serious concerns about the energy losses that will occur in the future.

whitepaper Multicast - What Is It?2008-10-03 Global Knowledge
  When multiple receivers are required to get the same data at approximately the same time, multicast is a more efficient way of delivering data than unicast. A unicast packet has a single source IP address and a single destination IP address. A multicast packet has a single source IP, but it has a multicast destination IP address that will be delivered to a group of receivers. This white paper explains the advantages of multicast over unicast delivery.

whitepaper Using Adaptive Bandwidth Allocation Approach to Defend DDoS Attacks2008-10-01 National Tsing Hua University
  Denial of service attacks occur when the attacks are from a single host, whereas distributed denial of service attacks occur when multiple affected systems flood the bandwidth or resources of a targeted system. Although it is not possible to exempt entirely from denial of service or distributed denial of service attacks, they can limit the malicious user by controlling the traffic flow. The paper proposes to monitor the traffic pattern in order to alleviate distributed denial of service attacks. A bandwidth allocation policy will be adopted to assign normal users to a high priority queue and suspected attackers to a low priority queue. Simulations conducted in network simulator of their proposed priority queue-based scheme shows its effectiveness in blocking attacking traffic while maintaining constant flows for legitimate traffic.

whitepaper Video Surveillance Trade-Offs - A Question of Balance: Finding the Right Combination of Image Quality, Frame Rate and Bandwidth2008-10-01 Motorola
  As video surveillance technology becomes indispensable in public safety and law enforcement around the world, one thing is clear: image quality is paramount. The benefits of video surveillance - from monitoring and real-time protection to investigation and evidence preservation - are largely dependent on the quality of the images transmitted by digital video surveillance cameras and networks. To balance the need for high quality images with the need for affordable solutions, network designers and operators have to make certain trade-offs. In this discussion, it will introduce these trade-offs to help CIOs and other professionals understand the factors they must consider in planning and deploying efficient, cost-effective video surveillance networks.
