2 SDN NFV B U S BBF projects driving growth of holistic broadband Holistic Broadband A commitment that results in a set of inter-related BBF deliverables enabling provider differentiated services Is not a monolithic system designed for specific closed solutions USP 2

3 Virtualized broadband: CloudCO SDN/NFV WA CloudCO is a project of the BBF SDN/NFV Work Area CloudCO is a comprehensive set of deliverables that collectively enable dramatically faster, more efficient provisioning of Cloud-based services Based on NFV and SDN implementation, YANG models, Cloud consumption interfaces/functions Utilizes Open Broadband for ongoing development, testing and deployment staging Multi-Dwelling / Professional Building Wireless-Wireline Converged Transport Interconnect Remote Provider Domains 68 o Homeworker Street Cabinet 3
