Virtual Central Office An Edge Blueprint OPNFV Community Demo

What is VCO? Cloud Native approach to deploying NFV closest to subscriber One of the Edge Blueprints as discussed in the community Based on OpenStack and Kubernetes Massive Scale => Large Number of sites

VCO Progression Telco CO - Traditional Status COs Serve Residential, Business & Mobile Customers Telco CO - Traditional Status Telco COs - Modernization Telco COs - Cloud Native Closed, Rigid and Complex Variety of Access & Speeds Wide variety of hardware – routers, switches, gateways, servers etc Lack of standard interfaces => lack of programmability Virtualization Reduction in CAPEX and OPEX by >30% Open and Flexible & Standardized Software Defined Network Orchestration Programmability Fully Software Defined Further Reduction in CAPEX and OPEX Disaggregated and flexible Massive Scale Edge Blueprint

VCO 1.0 Recap 2017 OPNFV Summit in Beijing: Phase I of the Project: Residential Services and Enterprise Business Services live on stage (vOLT, VNFaaS, BNG, etc) Generic blueprint for Central Office with open source components and OpenDaylight SDN controller Focus on residential and enterprise VNF on-boarding and assurance
