The Office of Science (SC) in the U.S. Department of Energy (DOE) relies on a wide range of advanced network technologies to support its scientific activities. This topic addresses the development and deployment of advanced high-speed network technologies needed to support distributed tera-scale supercomputing, the remote controls of scientific instruments, distributed data storage, and large-scale secure scientific collaboration in SC programs. In particular, emerging large-scale science experiments in many SC programs (such as high-energy physics, nuclear energy, computational genomics, climate modeling, etc.) are expected to generate several petabytes of data, which will be transferred to geographically distributed tera-scale computing facilities for analysis and visualization by thousands of scientists. These distributed large-scale science activities require networks with unprecedented bandwidth and capabilities. This topic focuses primarily on system-level, ultra high-speed (10 Gbps and beyond) network technologies. Current areas of interest include, but are not limited to: (1) ultra high-speed transport protocols, (2) dynamic provisioning of Dense Wave Division Multiplexing (DWDM)-switched networks, and (3) ultra high-speed cyber security systems. Additional information on the DOE networking requirements can be found in the reports of the following workshops: DOE Science Networking Challenge: Roadmap to 2008 (http://www.es.net/hypertext/welcome/pr/Roadmap/), DOE workshop on High-Speed Transport Protocols and Dynamic Provisioning for Large-Scale Science Applications (http://www.csm.ornl.gov/ghpn/wk2003), and the High-Performance Network Planning Workshop (http://www.doecollaboratory.org/meetings/hpnpw/). Grant applications are sought only in the following subtopics:
a. Ultra High-Speed Network Technologies—Emerging large-scale distributed science applications increasingly depend on networks with unprecedented bandwidth capabilities to support distributed tera-scale computing and scientific collaboration. These networks are expected to securely deliver guaranteed ultra high-speed end-to-end throughputs (10-100 Gbps) to distributed high-end science applications. Achieving such levels of end-to-end performance will require advanced network technologies that are radically different from today’s commercial Internet protocol (IP) networks, which are designed to deliver best-effort services. Grant applications are sought to develop system-level network technologies (hardware and software) that can securely deliver multi-Gigabits/sec throughput to high-end scientific applications. Technical areas of interest include, but are not limited to, cost effective 10 Gbps network Interfaces, Transmission Control Protocol (TCP) and User Define Protocol (UDP) extensions for ultra high-speed data transfers, non-TCP transport protocol technologies, high-speed I/O and storage systems, and Operating System (OS)-bypass over wide-area networks, and ultra high-speed cyber security systems. Device-level network technologies (such as laser, optical signal processors, low-level hardware components, etc.) are beyond the scope of the current announcement.
b. Dynamic Provisioning Network Technologies—DOE recently funded a nation-wide high-capacity optical network testbed called Ultra-Science Net for developing, testing, and deploying user-controlled, dynamic provisioned, DWDM-based, optical network technologies. The goal of Ultra Science Net is to develop, test, and deploy advanced DWDM networks that are transparent to transport protocols and can be dynamically provisioned to provide on-demand end-to-end circuits and related services. The testbed, which is based on the Generalized Multiple Protocol Label Switching (GMPLS) standard for optical internetworking, has a switching capacity of 20 Gbps and expected to reach 40 Gbps capacity by 2006. Grant applications are sought to develop network technologies to support dynamic provisioning of secure end-to-end optical channels, bandwidth reservation and scheduling, and security mechanism for GMPLS services. Technical areas of interest include, but are not limited to: resource discoveries; bandwidth scheduling; GMPLS security; integration of end-to-end signaling technologies [Transaction Language 1 (TL1), GMPLS, and Multiple Protocol Label Switching (MPLS)], and conceptual frameworks such as inter-domain signaling architectures; circuit/wavelength routing; circuits exchange; and GMPLS traffic engineering. Further information on the Ultra-Science net testbed can be found at http://www.csm.ornl.gov/ultranet/.
c. High-Speed Network Security Systems—Grant applications are also sought to develop scalable cyber security systems that can operate at speeds up to 10 Gbps and beyond. Technologies of interest include ultra high-speed Intrusion Detection Systems (IDS), firewall systems, authentication systems for GMPLS control plane, and optical layer security services. Grant applications must address the scalability issues associated with their proposed approaches by demonstrating how the resulting security system be will operated at 10 GigE and OC-192 (Optical Carrier Level 192).
