Design Guidelines for IT Security Management Tools

White Paper One of the most important factors that impact usability of security systems within an organization are security tools. This paper reports preliminary results of their survey about design guidelines for IT security management tools. [04 Aug 2008]

A Review of QoS Architectures

White Paper Over the past several years there has been a considerable amount of research within the field of Quality of Service (QoS) support for distributed multimedia systems. To date, most of the work has occurred within the context of individual... [04 Aug 2008]

Dynamic Injection Control Module for Optical Packet Switching Fabrics

White Paper Optical Packet Switched (OPS) networks offer the unique combination of encompassing the enormous capacity of the optical domain while providing versatile connectivity afforded by individual packet routing. [18 Jul 2008]

10 Gbps NRZ-DPSK Modulation in SOA-Based Optical Packet Switching Networks

White Paper Optical Packet Switched (OPS) networks are a promising means of delivering high bandwidth data communication with the fine granularity enabled by individual packet routing. In most OPS network architectures, Semiconductor Optical Amplifiers (SOA... [18 Jul 2008]

Ultra Low Latency Optical Networks

White Paper In many supercomputing applications, High Data Reference Locality (HDL) allows hardware and software designers to reduce the impact of long data access latency through caching and migration techniques. [18 Jul 2008]

A Specific Domain Language for Network Interface Cards

White Paper Writing a device driver has never been pleasant. Maintaining or updating the driver is almost hard. This paper addresses this problem by suggesting the use of Specific Domain Language (SDL) for the programming of the device. [11 Jul 2008]

Surveillance Detection in High Bandwidth Environments

White Paper This paper describes System Detection's surveillance detection techniques for enclave environments (ESD) and peering center environments (PSD) and evaluates each technique over data gathered from two different network environments. [11 Jul 2008]

Exploring Eye Tracking to Increase Bandwidth in User Modeling

White Paper The accuracy of a user model usually depends on the amount and quality of information available on the user's states of interest. An eye-tracker provides data detailing where a user is looking during interaction with the system. [11 Jul 2008]

EasyVPN: IPsec Remote Access Made Easy

White Paper Telecommuting and access over a Wireless LAN require strong security at the network level. Although IPsec is well-suited for this task, it is difficult to configure and operate a large number of clients. [10 Jul 2008]

Adaptive Model Generation for Intrusion Detection Systems

White Paper This paper presents adaptive model generation, a method for automatically building detection models for data-mining based intrusion detection systems. Using the same data collected by intrusion detection sensors, adaptive model generation builds... [10 Jul 2008]

Achieving High Throughput in Low Multiplexed, High Bandwidth, High Delay Environments

White Paper This paper explores combining ECN bits and loss feedback to achieve a high throughput connection in a high bandwidth, low multiplexed environment. In the scheme, a TCP source reacts differently on receiving an ECN than it does on inferring a packet... [08 Jul 2008]

A Unified Scheduling Approach for Guaranteed Services Over IEEE 802.11e Wireless LANs

White Paper Supporting real-time multimedia applications in any network requires scheduling techniques that can provide guaranteed delay and/or bandwidth to media streams. Coordinating access to the wireless medium in an IEEE 802.11 wireless LAN is different... [03 Jul 2008]

Capital Wireless Integrated Network (CapWIN): Building a Bridge in Transportation and Public Safety Communications

White Paper The Capital Wireless Integrated Network (CapWIN) program is a partnership between federal agencies, States of Maryland, Virginia, and the District of Columbia to develop an integrated first responder communication and information sharing network. [03 Jul 2008]

Should Workers Care About Firm Size?

White Paper The question of wage differentials by firm size has been studied for several decades with no commonly accepted explanations for why large firms pay more. This paper reexamines the relationship between firm-size and wage outcomes by estimating the... [03 Jul 2008]

Gender Role Attitudes and the Labour Market Outcomes of Women Across OECD Countries

White Paper After two decades of spectacular gains, in many OECD countries (e.g. Austria, Canada, Denmark, Ireland, Italy, Portugal, Sweden, United States) progress in the gender pay gap has more or less stalled since the mid 1990s. [03 Jul 2008]
