whitepaper Design, Implementation and Evaluation of a QoS-Aware Transport Protocol2008-06-04 University of New South Wales
  In the context of a reconfigurable transport protocol framework, the paper proposes a QoS-aware Transport Protocol (QSTP), specifically designed to operate over QoS-enabled networks with bandwidth guarantee. QSTP combines QoS-aware TFRC congestion control mechanism, which takes into account the network-level bandwidth reservations, with a Selective ACKnowledgment (SACK) mechanism in order to provide a QoS-aware transport service that fill the gap between QoS enabled network services and QoS constraint applications. The paper has developed a prototype of this protocol in the user-space and conducted a large range of measurements to evaluate this proposal under various network conditions.

whitepaper Clean VPN Approach to Secure Remote Access2008-06-02 SonicWall
  A SonicWALL Clean VPN can detect the identity of users and security state of the endpoint device, protect against malware and unauthorized access based on granular policy before authorizing access, and connect authorized users easily to mission-critical network resources. Only SonicWALL is capable of delivering a truly viable Clean VPN, because only SonicWALL can offer granular endpoint control, a unified policy model allowing dynamic access policies, and the revolutionary ultra-high-performance security of Reassembly-Free Deep Packet Inspection over a multi-core processing platform.

whitepaper An Architectural Model to Provide QoS in a Home Network and Its Evaluation in a Real Testbed2008-06-01 Academy Publisher
  Home networks are an evolution of office local area networks, answering the need for residential distribution of broadband services. The design of a home network must strive to keep low costs, easy installation and maintenance while at the same time providing a large variety of services, from voice and data applications to multimedia streaming. A successful platform for home networking must put together simple interfaces for the users and sophisticated mechanisms for managing the distribution of the desired broadband services. This paper proposes mechanisms to support flows with different Quality of Service (QoS) requirements in a home network whose architectural model has been defined in the framework of the European IST ePerSpace project.

whitepaper Virtual Private Networks - Solutions for Secure Remote Access2008-06-01 Decipher Information Systems
  Virtual Private Networks, or VPNs, have become an essential part of company network infrastructures both large and small. The ability for users to access resources in an internal corporate network securely from remote locations has created a wealth of opportunities for companies both from a functional as well as convenience standpoint. The technology involved in creating secure network connections over the public Internet is complex, and can involve a number of communications protocols along with various hardware and software components. This paper will provide an overview of VPNs. Topics of discussion include the responsibilities of a VPN, essential elements, tunneling protocols, and risks associated with using VPNs.

whitepaper Padua Hospital Conducts Infrastructure Check-Up and Calls on Extreme Networks to Boost Network Health2008-06-01 Extreme Networks
  Padua Hospital was faced with network slowdowns and was often vulnerable to instability caused by traffic spikes and security threats. With a need to service over 5,000 users, the hospital needed a segmented and redundant network to ensure life-saving applications would work to serve its patients' needs 24/7. Padua Hospital deployed Extreme Networks which provided a complete solution that would provide the reliability and performance necessary for high-performance applications and around-the-clock traffic. The new Extreme Networks high-performance network is more robust and capable of handling the hospital's users, traffic spikes, and bandwidth-intensive technologies, able to transport massive files without delay or degradation.

whitepaper A Two-Stage Plug-in Bandwidth Selection and Its Implementation for Covariance Estimation2008-06-01 Concordia University
  The two most popular bandwidth choice rules for kernel HAC estimation have been proposed by Andrews (1991) and Newey and West (1994). This paper suggests an alternative approach that estimates an unknown quantity in the optimal bandwidth for the HAC estimator (called normalized curvature) using a general class of kernels, and derives the optimal bandwidth that minimizes the asymptotic mean squared error of the estimator of normalized curvature. It is shown that the optimal bandwidth for the kernel-smoothed normalized curvature estimator should diverge at a slower rate than that of the HAC estimator using the same kernel.   
whitepaper Accelerating Mission-Critical Oracle Applications Throughout the Distributed Enterprise2008-06-01 Juniper Networks
  From Oracle E-Business Suite to PeopleSoft Enterprise, Siebel, JD Edwards EnterpriseOne, and JD Edwards World, Oracle offers a full complement of integrated business solutions that improve functional best practices, integrate Web services, provide predictive analysis and enable more flexible, collaborative business processes. Many businesses today rely on Oracle applications to support their ongoing business operations. However, globalization and server centralization create performance problems for remote and branch-office users accessing these applications over the WAN. The WX and WXC application acceleration platforms from Juniper Networks accelerate the performance of Oracle business applications over the WAN. Remote and branch-office users receive LAN-like response times, regardless of their location.

whitepaper Extreme Networks Supports Wireless Mobility at Patient Bedside for St. Johannes Hospital2008-06-01 Extreme Networks
  St. Johannes Hospital in Troisdorf-Sieglar, Germany, with just over 400 staff members, has more than 182 beds and treats approximately 8,800 inpatients and as many outpatients each year. The Hospital Information System (HIS) was looking to create a virtually paperless hospital operations chain in addition to its existing implementation of PACS. Ideally, the intent was to have all patient information processed and stored digitally and made available to its staff whenever and wherever needed. The hospital deployed Extreme Networks for its infrastructure, with the redundancy provided by Extreme Standby Router Protocol (ESRP), a hot-standby failover mechanism for Layer 2 and Layer 3 IP networks.
