RSS electricalDynamic Routing in Translucent WDM Optical Networks
White Paper Translucent WDM optical networks use sparse placement of regenerators to overcome the impairments and wavelength contention introduced by fully transparent networks, and achieve a performance close to fully opaque networks with much less cost. [18 Jul 2008]
Joint Source-Channel Multistream Coding and Optical Network Adapter Design for Video Over IP
White Paper This paper presents a panorama picture on how to achieve end-to-end video over IP service under the communication environments, consisting of backbone networks, hybrid access networks, and the end users. [18 Jul 2008]
Optical Switching: Switch Fabrics, Techniques, and Architectures
White Paper The switching speeds of electronics cannot keep up with the transmission capacity offered by optics. All-optical switch fabrics play a central role in the effort to migrate the switching functions to the optical layer. [18 Jul 2008]
GlueQoS: Middleware to Sweeten Quality-of-Service Policy Interactions
White Paper A holy grail of component-based software engineering is "Write-once, reuse everywhere". However, in modern distributed, component-based systems supporting emerging application areas such as service-oriented e-business (where web services are viewed... [17 Jul 2008]
Chip Multi-Processor Scalability for Single-Threaded Applications
White Paper Designers have been unable to scale performance while managing thermal, power, and electrical effects. While this approach mitigates the issues with design complexity, power, and electrical effects, it does nothing to directly improve the... [11 Jul 2008]
Package Technology to Address the Memory Bandwidth Challenge for Tera-Scale Computing
White Paper The scope and focus of the paper are primarily design and electrical performance challenges. Tera-scale computing stresses the platform architecture with memory bandwidth being a likely bottleneck to processor performance that presents unique... [11 Jul 2008]
Optimizing the Internet Gateway Deployment in a Wireless Mesh Network
White Paper In a Wireless Mesh Network (WMN), Mesh Routers (MRs) are interconnected by wireless links and form a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients. The wireless backbone is tightly integrated with the... [11 Jul 2008]
ARCH-Based Traffic Forecasting and Dynamic Bandwidth Provisioning for Periodically Measured Nonstationary Traffic
White Paper Network providers are often interested in providing dynamically provisioned bandwidth to customers based on periodically measured nonstationary traffic while meeting Service Level Agreements (SLAs). This paper proposes a dynamic bandwidth... [11 Jul 2008]
Memory and Network Bandwidth Aware Scheduling of Multiprogrammed Workloads on Clusters of SMPs
White Paper Symmetric Multiprocessors (SMPs), combined with modern interconnection technologies are commonly used to build cost-effective compute clusters. However, contention among processors for access to shared resources, as is the main memory bus and the... [11 Jul 2008]
Coexistence Issues in Cognitive Radios Based on Ultra-Wide Bandwidth Systems
White Paper This paper discusses the basic concepts underlying Cognitive Radio (CR) and investigates the Ultra Wide Bandwidth (UWB) technology as one of the enabling transmission techniques for the implementation of CR systems. [11 Jul 2008]
MPLS Based Best Effort Traffic Engineering
White Paper The advent of Multi-Protocol Label Switching (MPLS) enables traffic engineering by introducing connection-oriented features of forwarding packets over arbitrary non-shortest paths. The goal of this research is to improve the network utilization for... [11 Jul 2008]
Restoration Algorithms for Virtual Private Networks in the Hose Model
White Paper A Virtual Private Network (VPN) aims to emulate the services provided by a private network over the shared Internet. The endpoints of a VPN are connected using abstractions such as Virtual Channels (VCs) of ATM or Label Switching Paths (LSPs) of... [11 Jul 2008]
A CSMA/CP MAC Protocols for IP Over WDM Metropolitan Area Ring Networks
White Paper To solve the explosively growth of the Internet demands, Metropolitan Area Networks (MAN) use SONET to provide huge bandwidth. However, the SONET network is suitable for Constant Bit Rate (CBR) traffic. [11 Jul 2008]
Relation Between Willingness to Pay and Guaranteed Minimum Bandwidth in Multiple-Priority Service
White Paper Off late, the necessity of quality guaranteed services is increasing in the Internet. The differentiated services, which have multiple classes using priority control, are being introduced. Various issues need to be addressed when providing... [11 Jul 2008]
Dynamic Bandwidth Allocation Schemes to Improve Utilization Under Non-Uniform Traffic in Ethernet Passive Optical Networks
White Paper In this paper, conventional bandwidth allocation schemes in Ethernet Passive Optical Network (EPON) are shown to suffer from poor utilization under the non-uniform traffic, particularly as the number of ONUs, guard time and round-trip time increase. [11 Jul 2008]
