2. Virtual Central Office
An Edge Blueprint
OPNFV Community Demo

3. 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

4. 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

5. 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

OPNFV initial goal is to provide telco NFV cloud reference platform
When it comes to edge, think if telco cloud can provide edge services and infrastructure
Telco CO provide natural infra base for edge cloud, since there are enough CO fully distributed at the edge
