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

Step #2: Order Arrives • From OM according to
RFS service model (instantiate)
• 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

PNF
• Order comes in to remove firewall service from chain
• 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
