Agenda

• What is Network Function Virtualization (NFV)?

• NFV Lab Overview

• Network Services Orchestrator (NSO)

• Elastic Services Controller (ESC)

• Cisco Virtual Topology System (VTS)


What is Network Function Virtualization (NFV) ?

• Definition NFV decouples the network functions such as NAT, IPS, DNS, RR etc from proprietary hardware appliances, so they can run in software.

• VisionAn open ecosystem for NFV enables rapid service innovation for Network Operators and Service Providers. Innovation in end-to-end services is enabled by software-based deployment and operationalization of virtualized network functions on independently deployed and operated NFV infrastructure platforms.

Network Services Orchestrator (NSO)

Orchestration: Network Services Orchestrator (NSO)

• Multi-vendor service orchestrator for existing and future networks

• Single pane of glass for:

• L2-L7 networking

• Hardware Devices

• Virtual Appliances

• Model Driven Orchestration

• Service Data models (declarative)

• Device Data Model (for auto config)

• All Models are YANG Based

• Highly Scalable for large infrastructure

• One of the existing deployment is managing 60K devices on the network

• In Lab setup, Cisco IOS XRv will be provisioned by NSO
