New protocol speeds up Internet resource sharing

30.01.2003


A Penn State researcher has developed a faster method for more efficient sharing of widely distributed Internet resources such as Web services, databases and high performance computers.

Jonghun Park, assistant professor in Penn State’s School of Information Sciences and Technology (IST) who has proposed the protocol, says the new technology speeds up to 10 times faster the allocation of Internet resources.

"In the near future, the demand for collaborative Internet applications will grow," Park says. "Better coordination will be required to meet that demand, and this protocol provides that."



The Penn State scientist describes his research today (Jan. 29) in a paper, "A Scalable Protocol for Deadlock and Livelock Free Co-Allocation of Resources in Internet Computing," at IEEE’s Symposium on Applications and the Internet in Orlando, Fla.

Park’s proposed algorithm enables better coordination of Internet applications in support of large-scale computing. The protocol uses parallel rather than serial methods to process requests. That helps with more efficient resource allocation as well as solves the problems of deadlock and livelock caused by multiple concurrent Internet applications competing for Internet resources.

The new protocol also allows for Internet applications to choose among available resources. Existing technology can’t support making choices, thereby limiting its utilization. Its other advantage: Because it is decentralized, Park’s proposed protocol can function with its own information. That allows for collaboration across multiple, independent organizations in the open environment of the Internet. Existing protocols require communication with other applications - - not feasible in the open environment of the Internet.

Internet computing -- the integration of widely distributed computational and informational resources into a cohesive network -- allows for a broader exchange of information among more users than is possible today. Those can range from the military and government to businesses.

One example of such collaboration is Grid Computing that, much like electricity grids, harnesses available Internet resources in support of large-scale, scientific computing. Right now, the deployment of such virtual organizations is limited because they require a more sophisticated method to coordinate the resource allocation. Park’s decentralized protocol could provide that.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
