Key Themes and Issues

• Connecting with other networks
• HOPI, DRAGON, Ultra-Science Net, NASA and
  inter-national networks
• Add new users and applications
• Remote visualization, Grid-computing,
  Web-download
• Inter-domain routing and signaling issues
• Heterogeneous path setup in multi-region and
  multi-layer networks (nested, stitched,
  contiguous LSP signaling)
• End host transport protocol and signaling engine
• Control plane security
• Scalability (distributed approaches)

Key Research

• Decision on initiating CHEETAH circuit set-up
• CAC and Bandwidth sharing modes
• Scheduled vs. immediate-request
• Long vs. short durations
• Granularities of calls
• Varying bandwidth rates
• Inter-domain Routing.
• Inter-domain Traffic engineering.
