  16. Conclusions • Trends • How to provide reconfigurability in Optical networks • Signaling extensions to accommodate reconfigurability in optical networks (GMPLS, RSVP) • Cross Layer Design • Handle physical impairments in all-optical networks • Routing in multi-domain networks • Constraint-based routing and regenerator placement • Survivable optical networks • Survivability considering multiple failures • Availability parameter modeled by considering the real “cumulative down time” rather than probabilistic metric • Use of reprovisioning and reoptimization techniques.

  17. Conclusions – Contd. Trends Supporting distributed computing over optical Grid networks Dynamic Bandwidth provisioning Allocate network resources and computational resources Ethernet everywhere (including core networks) Needs to provide huge capacity (100 G line rate in core) to the apps of the future Challenges of provisioning Ethernet for high bw rates pipes, over long distances.
