## Background

- Started working on a design for an upgraded ISS communications system nearly three years ago
- Original work funded by the NASA Glenn Research Center
- The ISS Advanced Comm Working Group (ACWG) was an outgrowth of this early effort
- The concept was further developed by Lockheed Martin Space Operations through the Consolidated Space Operations Contract (CSOC) in relation to CSOC’s Contract Option 6, which articulated an upgrade of the ISS Return Link Data Service to 150 Mbps (Option 6 was subsequently canceled due to lack of funds)
- The Lockheed Martin design includes some early analysis of Space Qualification requirements for ISS hardware
- Concept developed more energy with the introduction of DREAMTiME in June of 2000
- The end-to-end network architecture was demonstrated  in April at the National Association of Broadcasters annual convention in Las Vegas, NV
