Our industry challenge is
network complexity
Public

3. 3 © Nokia 2015
Networks growth in scale, scope, features and
interactions generates ever higher number of
operations, amount of data, and more complex process
orchestration
Public
We create network complexity
(and it’s okay!)
Public

More automation and more insights
However…
“Automation is only as good as the insight that drives it”
Public
We can control complexity
(hopefully…)

Automation without insight = Operating “in the dark”
Insight without automation = Operating “in the past”

Towards the Automation
Continuum
Public

7. 7 © Nokia 2015
In its simplest form automation is the
action of making a task executable
without human intervention.

Networks are already well but
fragmentarily automated systems.

An approach for combining function automation with
process automation
Applies from individual functions to orchestration of
entire chain of automation i.e. workflows

The Automation Continuum
Public

11. 11 © Nokia 2015
• “Deep” automation: vertically end-to-end
across the protocol stack or from the service-layer to the physical-layer
• “Wide” automation: horizontally end-to-end
across different technologies or administrative domains
• Repeatable and reusable in different contexts
relies on standardized or best current practices for interfaces and models
• Provisioning customizable “control or touch points” in the end-to-end
automation loop for human supervision

Challenges

Automation challenges
• Diversity. How to design
automation patterns applicable to
the heterogeneity of devices and
components
• Reliability. How to avoid massive
error propagation when extreme
automation is deployed
• Uncertainty. How to automate
when faced with lack of knowledge
or variability of the environment or
conditions
Automation means
• Measurement
by using streaming telemetry and analytics
to generate actionable insights
• Learning
by using machine learning to identify
patterns and enable predictive operations
• Decision
by using cognitive and adaptive closed
control loops to produce effective (re)action
plans
• Governance
by using powerful, declarative abstractions
(e.g. intents)

ETSI ZSM
ZSM leadership:
• Chair: Klaus Martiny, DT
• Vice chairs:
• Nurit Sprecher (Nokia)
• Christian Toche (Huawei)
• NOC Advisory Group Chair: Ashiq Khan (DOCOMO)
ZSM objectives
• Define an end-to-end automated network and service management architecture
• Support both legacy and virtualized network infrastructures
• Collaborate with relevant open-source projects, standardization bodies and fora
• Create a foundation for diverse open source groups to produce interoperable solutions
The ZSM group continues growing in a steady pace

Industry alignment
ETSI ZSM has a central role in the automation ecosystem
• ETSI ZSM has a pivotal role in bridging
between holistic end-end automation and
other standardization bodies or open source
projects
• Requirements derived from use cases
• Architecture for management/automation
• Open-source projects like ONAP focus on
implementation and validation
• Alignment discussion with LNF and ONAP
already started
