Why Automate?

Execution at the speed of software

!  Agility, DevOps, NFV, SDN, new services platforms

Rapidly changing business models

!  Cloud services, virtualization, programmable networks

!  New ecosystems and value chains

!  OTT co-opetition

Changing customer behavior and new

expectations

!  Everything on demand !  New services with a press

of a button

All of this requires successful, flexible automation. But complexity has destroyed many automation initiatives.

•  Networks are physical, virtual, interfaced through SDN controllers, NFV Orchestrators, or traditional means (CLI)

•  Revenue not driven from creating VMs or configuring SDN applications — but end-to-end services

NFV Service – Necessary, but not Sufficient

ETSI NFV services

Network service: •  A set of VNFs with optional

VNF forwarding graphs •  Configuration of VNF is out of

scope •  Examples: Deploying vEPC

•  Spans several Network Elements

•  One Network Element supports multiple services instances.

•  Examples: E-Line, VPN, VOIP connection, 4G mobile data

“Service Provider” Services

•  Order spans physical end-points, but also virtual router and firewall

•  NSO starts a transaction

Step #3: Stateful Convergence •  NSO decomposes operation into

required actions: 1.  Configure PNFs 2.  Deploy and stitch VNFs

(FW and vRouter) according to NSD and VNFDs

3.  Configure VNFs •  Close transaction on success

•  Order comes in to remove service •  NSO decomposes operation:

1.  Remove NSR and associated VNFRs and destroy VNFs

2.  Clean up configuration on PNFs

•  NSO decomposes operation: 1.  Replace running NSR with

new, smaller NSD instance including new VLDs

2.  Update configuration on vRouter

3.  Update configuration on PNFs
