After decades of limited applications, IP and optical integration is making a strong comeback due to significant advances on both the software and the hardware front. The software technology enabler is SDN which provides a centralized control and management layer cutting across multiple layers and multiple vendors – for the first time in history. SDN-based interworking brings interworking benefits without requiring any physical hardware integration. At the same time, physical IP and optical integration has a new life based the combination of merchant silicon, pluggable optics modules, and open APIs. The new line side pluggables insert directly into layer 2/3 switches, eliminating short-reach optics, and promise multi-vendor interoperability – another break from past architectures.
This panel looks at both SDN-based multi-layer interworking and physical multi-layer integration from an architectural perspective, with a focus on the drivers, benefits, technology enablers, and primary applications for each.
- Where does physical integration make most sense in the network?
- Where does control/management plane integration make most sense?
- What is the role of SDN in both architecture types?
- What are differences in architectural preference among different types of service providers, such as traditional telecom vs. Webscale vs cloud?
- For most service providers will the IP and optical integration decision be one or the other? Or both?
- What are the main challenges to be addressed to move forward with each architecture type?
