2. Principles and Selected Approaches Diversity of options Slicing Separation of concerns Separation of interdomain and intradomain routing Separation of identity from trust (self-certifying names) Decoupling application from the network High level API to data plane Replication (of paths, resources, etc.) Support for multipath routing Open APIs to data and control plane Software-defined networking Integrated measurement Networks that learn

3. Reconsidering the Abstraction Path Segments: Unit of connectivity –Each independently operated network advertises connectivity between two intermediate points (ingress, egress, price, ) Intermediaries: Mechanism for “stitching” paths together to match segments to end-to-end paths

4. Separating Interdomain from Intradomain Path Segments: Unit of connectivity –Each independently operated network advertises connectivity between two intermediate points (ingress, egress, price, ) Mediators: Mechanism for “stitching” paths together to match segments to end-to- end paths Monitor Network State Segment Prices Mediator Segment Database Path Computation Segment Updates Path Requests

5. Benefits of Separation Independent innovation and evolution –Each independently operated network can deploy its own protocols within the network Improved isolation –As long as independently operated network can maintain the abstraction, no need for readvertisement Direct value transfer –Possibility of directly paying for and end-to-end path
