Advanced Technology Demonstration Network (ATDNet)
Objective: Provide HPCC ESS and NREN Projects with an effective testbed for gigabit network R&D.
Approach: Participate in Washington, DC-based 2.4 Gbps SONET/ATM metropolitan area network testbed involving and interconnecting the Advance Research Projects Agency, the Defense Intelligence Agency, the Defense Information Systems Agency,, Goddard Space Flight Center (GSFC), the Naval Research Laboratory, and the National Security Agency. With NASA NREN Project, investigate and resolve problems with multivendor standards-based SVC interoperability, IP addressing, routing, multicasting, and firewalling over ATM.
Accomplishments: Successfully updated and demonstrated ATDNet since its Initial Operating Configuration on May 1, 1994. Initiated plans to support ARPA-funded ACTS experiments using HDRT at GSFC accessed via ATDNet. Implemented plans that extend ATDNet to GSFC's Laboratory for Terrestrial Physics to enable ATM-based access to EROS Data Center via an interconnection of ATDNet and MAGIC as part of the ACTS ATM InterNetwork experiment. Prepared White Papers on "Integrated Routing and Addressing" and "Implementing Classical IP Over the ATDNet"
Significance: Participation in ATDNet facilitates significant leveraging of Department of Defense funding to develop solutions to problems inherent with TCP/IP-based communications over networks with a large bandwidth-times-delay product./P>
Status/Plans:
- FY96: Develop and use Protocol Implementation Conformance Statement (PICS) for Q.2931 signaling to evaluate vendor switches; and develop a reference implementation of proposed solutions for IP addressing and routing over ATM.
- FY97: Extend PICS testing to other vendors' switches and develop a reference implementation of proposed solutions for IP multicasting and firewalling over ATM.
