We explain why distributed control lacks the ability to optimally control networks with multiple transport domains or both IP/MPLS and Optical layers. We then propose a practical architecture to fix these issues and experimentally demonstrate it over commercial IP and transport gear.
This presentation describes challenges facing the evolution of the Optical layer.
- Data plane: multirate, multichannel, multicore
- Control plane: SDN
- Multilayer interworking
- Vision of the future network
