RSS massachusettsGoogle digs deep for geothermal energy
News The latest investments are meant to spur development of geothermal, which a study by Massachusetts of Institute of Technology last year found was underutilised. Google is investing $10m in "enhanced" geothermal systems - essentially technology for... [20 Aug 2008]
PowerDsine Case Study: Clark University
White Paper When Clark University in Worcester, Massachusetts, sought the benefits of adding power over Ethernet capability to their wireless LAN and security camera installations, Manager of Network Operations, put their in-house staff to work. [04 Aug 2008]
METERG: Measurement-Based End-to-End Performance Estimation Technique in QoS-Capable Multiprocessors
White Paper Multiprocessor systems present serious challenges in the design of real-time systems due to the wider variation of execution time of an instruction sequence compared to a uniprocessor system. Even if non-determinism is tightly controlled by adding... [04 Aug 2008]
OverQoS: An Overlay Based Architecture for Enhancing Internet QoS
White Paper This paper describes the design, implementation, and experimental evaluation of OverQoS, an overlay-based architecture for enhancing the best-effort service of today's Internet. Using a Controlled Loss Virtual Link (CLVL) abstraction to bound the... [04 Aug 2008]
High-Bandwidth Packet Switching on the Raw General-Purpose Architecture
White Paper The switching of packets and other performance-critical tasks in modern Internet routers are done using Application Specific Integrated Circuits (ASICs) or custom-designed hardware, while existing general-purpose architectures have failed to give... [04 Aug 2008]
Energy-Scalable Algorithms and Protocols for Wireless Microsensor Networks
White Paper Wireless microsensor networks lend themselves to trade-offs in energy and quality. In these networks, the individual sensor data per se is not necessarily important to the end user. Rather, it is the combined knowledge of all the sensors that... [04 Aug 2008]
INS/Twine: A Scalable Peer-to-Peer Architecture for Intentional Resource Discovery
White Paper The decreasing cost of computing technology is speeding the deployment of abundant ubiquitous computation and communication. With increasingly large and dynamic computing environments comes the challenge of scalable resource discovery, where client... [04 Aug 2008]
QoS Routing for Mesh-Based Wireless LANs
White Paper Wireless LANs with their increased data rate become an attractive technology for connecting mobile users to the Internet. Efficient deployment of wireless LANs will require the ability to extend the wireless LANs coverage without the need to deploy... [04 Aug 2008]
On the Capacity of Optical Networks: A Framework for Comparing Different Transport Architectures
White Paper This paper compares three optical transport network architectures: Optical Packet Switching (OPS), Optical Flow Switching (OFS), and Optical Burst Switching (OBS). This comparison is based on a notion of network capacity as the set of exogenous... [18 Jul 2008]
A Backup Route Aware Routing Protocol - Fast Recovery From Transient Routing Failures
White Paper As the Internet becomes the critical information infrastructure for both personal and business applications, survivable routing protocols need to be designed that maintain the performance of those services in the presence of failures. [18 Jul 2008]
Understanding the Interaction Between Overlay Routing and Traffic Engineering
White Paper This paper studies the interaction between overlay routing and MultiProtocol Label Switching (MPLS) Traffic Engineering (TE) in a single Autonomous System (AS). This interaction is formulated as a two-player non-cooperative non-zero sum game, where... [18 Jul 2008]
Non-Adaptive Fault Diagnosis for All-Optical Networks Via Combinatorial Group Testing on Graphs
White Paper This paper considers the fault diagnosis problem in all-optical networks, focusing on probing schemes to detect faults. This paper work concentrates on non-adaptive probing schemes, in order to meet the stringent time requirements for fault recovery. [18 Jul 2008]
Optimal Routing With Multiple Traf?c Matrices Tradeoff Between Average and Worst Case Performance
White Paper This paper considers the problem of finding an "Efficient" and "Robust" set of routes in the face of changing/uncertain traffic. The changes/uncertainty in exogenous traffic is characterized by multiple traffic matrices. [18 Jul 2008]
Optimal Routing With Multiple Traffic Matrices Tradeoff Between Average Case and Worst Case Performance
White Paper This paper considers the problem of finding an "Efficient" and "Robust" set of routes in the face of changing/uncertain traffic. The changes/uncertainty in exogenous traffic is characterized by multiple traffic matrices. [18 Jul 2008]
On the Throughput-Cost Tradeoff of Multi-Tiered Optical Network Architectures
White Paper This paper conducts a throughput-cost study of several optical network architectures: Optical Flow Switching (OFS), Tell-and-Go (TaG), Electronic Packet Switching (EPS), and Generalized MultiProtocol Label Switching (GMPLS). [18 Jul 2008]
