New Global Grid Computing and Communications Technology Demonstrated by Researchers in U.S. and Japan
— Demonstration Includes NCSU Virtual Computing Lab, Foreshadows Integration of Computing and Networking in the Next-Generation Internet
RESEARCH TRIANGLE PARK, N.C. (Sept. 11, 2006) – Researchers in the United States and Japan today demonstrated “automated” interoperability between network and computing resources in two national grid computing research testbeds – the first such demonstration of this scale between two countries of new, integrated computing and communication technology that can be used to exponentially enhance next-generation Internet performance.
The university and industry researchers believe that the future of information technology will include these types of capabilities - the direct integration of computing and the Internet across the globe.
The interoperability between the G-lambda project in
For the first time, a software application in a research testbed in one country was able to reserve, manage and monitor computing and network resources across both countries – a key milestone toward the development of a “global grid” of networked, interoperable resources, which some believe will lead to the next generation of computing and the Internet.
Grid technology is an evolution of computing, connecting computing and other resources. Grid computing spreads large or complex computer problems among multiple computers. It also enables sharing of expensive scientific equipment. For large-scale science research, called E-Science, grid technology is coupled with high-speed optical networks operating 10,000 times faster than broadband connections common to home computers.
Multiple computing platforms and data sources on the grid operate, and appear to a user, as a single computing system. Resources on the grid include the network, computers, storage systems, scientific instruments and software applications. Grid technology provides users with unprecedented computing power, services and information no matter where the resources are located.
Typically, the use of the high-performance computing resources and optical network resources are reserved and manually configured well in advance – a process that often requires weeks or more, and connections established for months or years.
Researchers working with the G-lambda group in Japan and the Enlightened Computing group in the United States demonstrated how software applications can establish network connections “on demand” to computing resources, databases of information and scientific instruments. The duration of these connections is based on the particular application’s requirement – for precisely the amount of time that is needed, and no more. Whether seconds or days, the network and resources are connected and managed to perform a task. Then, the connection is released in order to share resources for other purposes.
“This has been a wonderful collaboration to demonstrate the interoperability of resource management middleware,” said Tomohiro Kudoh of
The goal in developing next-generation optical networks is to extend the control of the network and resources to software applications – through what is called the “optical control plane.” The optical control plane controls the establishment, maintenance and release of connections in an optical network as well as algorithms for engineering an optimal path between resources.
The G-lambda and Enlightened Computing demonstration showed how grid technology dovetails with high-capacity optical networks. “The ability for end-users or applications to reserve and manage the network and compute resources in a coordinated manner is required to fully realize the potential of global grids” said Gigi Karmous-Edwards, principal scientist at MCNC, principal investigator for the Enlightened Computing project and chair of the GLIF Control Plane Working Group. “This demonstration shows evidence of new opportunities unfolding through the interoperability of global grid resources.”

Network Infrastructure Support
The networking resources have been made available by Cisco Systems through allocation grants to the Enlightened Computing Project, to the Louisiana Optical Networking Initiative (LONI) and to CalTech, on Cisco’s share of the National LambdaRail infrastructure.
The grant to the Enlightened Computing research project is for use of a 10 gigabit-per-second network connection from
While NLR and other research networks are not a part of the commercial Internet, the technology being developed by researchers today may evolve into the commercial services available to businesses and the general public in the future.
“NLR was developed to support research innovation and provide network gateways for researchers to use to collaborate with each other across the globe,” said Tom West, CEO of NLR.
“The Internet that people are familiar with today is being transformed by these new advanced technologies. The G-Lambda and Enlightened demonstration is a major advance toward creating a new global information technology environment that closely integrates computing and light-speed communications. These new capabilities are already allowing researchers to create a completely new generation of services and applications,” said Joe Mambretti, director of
IBM helping initiate the Virtual Computing Lab at NC State through a 2004 research grant is a prime example of industry and university collaboration leading to new services. IBM BladeCenter servers are part of the Virtual Computing Lab.
“IBM’s involvement in the Enlightened Computing project and the Virtual Computing Lab helps us understand the interaction among computing resources and the network in a global grid environment for the enablement of advanced services,” said Steve Hunter, IBM Distinguished Engineer, CTO, IBM BladeCenter.
With capabilities demonstrated today, we are enhancing opportunities for collaboration and sharing resources on global scale,” said John Crites, CEO of MCNC. “The accomplishment is an important step in unleashing the collective power of grid computing and fostering collaboration on a global basis. MCNC shares this success with NC State and all our partners in the N.C. Research and Education Network. It has been a collective effort from the beginning.”
A similar grid testbed interoperability demonstration is planned in November at Supercomputing 2006, an international conference on high performance computing and networking in

A key goal for the Japanese consortium was to demonstrate and familiarize the community with the GNS-WSI (Grid Network Services-Web Services Interface), a Web services interface between a grid resource management system and network resource management system for the purpose of standardization.
The demonstration also featured a Generalized Multiprotocol Label Switching (GMPLS) control plane including an External Network-to-Network Interface (E-NNI) available on Calient switches as a result of the collaboration between Calient Networks and KDDI R&D. This is the first time the GMPLS E-NNI was demonstrated across two countries to provide on-demand end-to-end lightpaths. The researchers plan on integrating the E-NNI capability into the middleware in the near future. Today’s demonstration of the E-NNI capability used the Calient Graphical User Interface (GUI) to create the end-to-end E-NNI path.
Enhanced E-NNI capability addresses optical network scalability and interoperability the same way SS7 did for the telephone network, says Olivier Jerphagnon from Calient Networks.
Many research challenges remain in the evolution of grid computing technology and optical networks. Several researchers involved in the demonstration co-edited a recently published book, “Grid Networks: Enabling Grids with Advanced Communication Technology,” co-edited by Franco Travistino, Joe Mambretti, and Gigi Karmous-Edwards.
