IDC Key Findings
YANG adoption and engagement is high
Adoption of YANG-based modeling technologies is expanding in
key and high-impact domains
• Business network services
Netconf reflects the broader trends and requirements for
operational systems

Orchestration and Automation
Service models using YANG reuses most of the building blocks and allows easier
service creation
© IDC Visit us at IDC.com and follow us on Twitter: @IDC 21
“Service agility is the most important
characteristic, network agility, to
compete with Internet players”
“Service product managers want to
fully automate the parsing of the
service in YANG models”
n
The only combination that allows a model-based
approach for fulfillment and service assurance
For our RFPs it is a
mandatory requirement
for netconf/YANG
support on all Layer 1-3
networking products
Only started using YANG
models in last 8 months and now 6 services are available
some are fully automated
Goal of netconf/YANG is to have a
"simpler interface" to talk to devices
NETCONF/YANG is a
fundamental part of the
company's transformation to
automate services
Simplification is Fundamental

Interview Highlights: Business Network Services Use
Cases
"absolutely multi-vendor support for YANG“
“we are building an abstraction layer so that we can use YANG models from any vendor
“It is a mandatory requirement for our 4 router vendors to support YANG going forward”

Network modeling and programmability enables
business leaders to achieve Business Targets for People, Process, & Technology
YANG, NETCONF and other modeling tools
(TOSCA, OpenConfig, WebConf) are helping
100% of CSPs surveyed to achieve
Operational Targets

Role of Cognitive Technologies
Cognitive and “hyper-automation” will increasingly impact networking
Impact of network evolution on operations:• Customers and CSP corporate plans demand agility
• SDN/NFV progress opens up new ways to run networks
Impact of data innovations on operations:• Open interfaces and data sources provide new types and volumes of data
• Big data/analytics innovations open up new ways to use data

Essential Guidance
Diverse, broad-based efforts to simplify networks are underway
Automation is a foundational step to achieving other goals Assess which part(s) of the network infrastructure are most important
Frame the discussion with both cost savings and business revenue enablement
Expect further developments in network automation

Foundation for Full Lifecycle Service Automation
Infrastructure
Cisco Orchestration ArchitectureHigh Level View
• Model-driven end-to-end service lifecycle and customer experience in focus
• Seamless integration with existing and future OSS/BSS environment
• Loosely-coupled and modular architecture leveraging open APIs and standard protocols
• Orchestration across multi-domain and multi-layer for centralized policy and services across entire network

Customer owns lifecycle of formal service definition
• Product management defines the services
• Infrastructure team deploys and manages
• Order Management team consumes the services
What You Gain with Cisco Automation
• Agility throughout service lifecycle
• Full automation
• Robust and proven in tier-1 deployments
• Industry’s broadest multivendor support
• Most scalable service orchestration
• ETSI MANO compliant NFVO, VNFM
• Relevant in today’s and tomorrow’s networks
