Converged Wireless Access/Optical Metro Networks in Support of Cloud and Mobile Cloud Services Deploying SDN Principles

This chapter proposes a next-generation ubiquitous converged infrastructure to support cloud and mobile cloud computing services. The proposed infrastructure facilitates efficient and seamless interconnection of fixed and mobile end users with computational resources through a heterogeneous network integrating optical metro and wireless access networks. To achieve this, a layered architecture which deploys cross-domain virtualization as a key technology is presented. The proposed architecture is well aligned and fully compliant with the Open Networking Foundation (ONF) Software-Defined Networking (SDN) architecture and takes advantage of the associated functionalities and capabilities. A modeling/simulation framework was developed to evaluate the proposed architecture and identify planning and operational methodologies to allow global optimization of the integrated converged infrastructure. A description of the tool and some relevant modeling results are also presented.

Black link versus cutting edge transceivers: A comparison for next generation WDM optical networks

We compare WDM optical networks employing Black Link interfaces versus proprietary-based transceivers. Future optimal use and coexistence of both approaches is analyzed using latest conceptual and experimental achievements at 400G and beyond.

Interconnected traffic engineering domains: A proof of concept for packet-optical convergence

Multi-Layer networks require alignment of topology information between layers to avoid routing loops and delayed convergence. We describe multi-vendor packet-optical integration using link abstraction utilizing SRLG to provide the necessary basis for coordinated between layers.
