- Using Random Subsets to Build Scalable Network Services
- This paper argues that a broad range of large-scale network services would benefit from a scalable mechanism for delivering state about a random subset of global participants. Key to this approach is ensuring that membership in the subset changes periodically and with uniform representation over all participants. Random subsets could...

- MACEDON: Methodology for Automatically Creating, Evaluating, and Designing Overlay Networks
- Currently, researchers designing and implementing large-scale overlay services employ disparate techniques at each stage in the production cycle: design, implementation, experimentation, and evaluation. As a result, complex and tedious tasks are often duplicated leading to ineffective resource use and difficulty in fairly comparing competing algorithms. This paper presents MACEDON, an...

- Data trips between light and sound
- As you probably are aware, future communications networks will certainly be based on optics. A research team led by Duke University physicists has done an important discovery which might lead to these future super-fast optical communications networks. The team has found a way to store information coming from a beam...

- Balancing Site Goals and Service Goals in Datacenter Management
- A shift is witnessed from large mainframe computing to commodity, off-the-shelf clusters of servers. The cluster paradigm allows organizations to acquire resources at a fine granularity, scaling the cluster to provide the resources necessary for increasingly-powerful simulations, multimedia rendering, and web farms. As yesterday's clusters grow into today's data centers,...

- Printing with enzymes
- Researchers at Duke University have developed a new printing technique using catalysts to create microdevices such as labs-on-a-chip. Their inkless printing technique uses enzymes from E. coli bacteria and has an accuracy of less than 2 nanometers. While they're are now using enzymes to stamp nanopatterns without ink, the research...

- CAD-CAM for nanotechnology manufacturing
- A team of U.S. researchers has used a computer aided design and manufacturing (CAD-CAM) process to guide an atomic force microscope AFM. According to them, this automated technique is 'paving the way for a nanotechnology's industrial revolution.' And their results look very promising. If they're confirmed -- and adopted by...

- Trade you some CO2 for a little O2
- I wouldn't hold my breath on anything getting done about the atmosphere and climate change in the current configuration of power in Washington D.C. But there are some rumblings that may hint about the next phase of American politics.Tuesday, July 24, 230pm Eastern Time, there's a subcommittee hearing in...

- iPhone off the hook
- Duke university has announced that the problem with iPhones interoperating on their wireless Cisco network has been solved. The problem was "caused by a Cisco-based network issue", says the university, and since Cisco provided a fix it has not reoccurred. Earlier reports that this was a problem with the iPhone...

- Characterizing Intrusion Tolerant Systems Using a State Transition Model
- Intrusion detection and response research has so far mostly concentrated on known and well-defined attacks. The authors believe that this narrow focus of attacks accounts for both the successes and limitation of commercial in Intrusion Detection Systems IDS. Intrusion tolerance, on the other hand, is inherently tied to functions and...

- Watch your future baby in 3-D
- If researchers from Duke University can successfully install an updated version of a new image-viewing software found on clinical ultrasound scanners, it soon could be possible to see developing fetuses in the womb in living 3-D movies. These 3-D ultrasound imaging systems dont need any additional hardware, except special goggles....

- TCP Performance Re-Visited
- Detailed measurements and analyses for the Linux-2.4 TCP stack on current adapters and processors are presented. The impact of CPU scaling and memory bus loading on TCP performance is also described. As CPU speeds outstrip I/O and memory speeds, many generally accepted notions of TCP performance begin to unravel. In-depth...

- A unified theory of animal locomotion
- You probably already know that there is a master equation for all life processes based on metabolism. Now, physicists from Duke University have applied the so-called 'constructal theory' to explain how running, flying and swimming modes of locomotion are similar even if they're apparently unrelated. And this single unifying physics...

- Broker Architectures for Service-Oriented Systems
- Brokering is an essential element of service-oriented architectures and utility resource sharing. Brokers act as intermediaries that match client needs with provider services by aggregating information about multiple providers and client requests. In these systems, broker architectures facilitate efficient and effective service management by distributing services to their "Highest and...

- Structure and Performance of the Direct Access File System
- The Direct Access File System DAFS is an emerging industrial standard for network-attached storage. DAFS takes advantage of new user-level net-work interface standards. This enables a user-level file system structure in which client-side functionality for remote data access resides in a library rather than in the kernel. This structure addresses...

- MobiNet: A Scalable Emulation Infrastructure for Ad Hoc and Wireless Networks
- The current state of the art in evaluating applications and communication protocols for ad hoc wireless networks usually involves either simulation or small-scale live deployment. Larger-scale live deployment is typically costly and difficult to run under controlled circumstances. Simulation allows more flexibility in varying system configurations, but requires the duplication...
