Survivable Networks

• Different forms of service, each with different
  dependability requirements, under different
  conditions.
• One or more alternate forms of service
  (different, less dependable, or degraded)
• Different services for different forms of damage
• Tradeoff functionality with resources

Survivable On going work

• Developing a parameter to quantify the robustness
  of a network design
• Developing a repair algorithm to use
  preconfigured protection cycles (P-cycles) to
  provide ring-like 25-50 ms restoration times in
  mesh networks.

What is a Grid?

• Grids are super Internets for high-performance
  computing worldwide collections of high-end
  resourcessuch as supercomputers, storage,
  advanced instruments, and immersive environments.
  These resources and their users are often
  separated by great distances and connected by
  high-speed networks.
