Before: Manually maintained network documentation
With INA: Daily updated digital twin of network topology
Fragmented / spread data collection in silos
No end-to-end view on the network
Error-proneness in manual documentation
Outdated, static planning data
Building a meta inventory is cost and time intensive
Contextual influence e.g. nw changes not considered
Inventories not in sync with the real network status
Analysis of network traffic flows not possible
Prediction of topology changes and impacts not possible

Web-based application: INA
Explorer utilizes thin web-
based visualization services
Great performance: Very fast
rendering of network layout
and computing of complex
analyses
High customizability: Graph
layout, edge crossing
avoidance method, and node
icons customizable at runtime
Customizable icons allow user-
dependent visualization
The complex calculation for
preventing edge crossings can
be performed at runtime.

INA‘s FEATURES

C2 - Eingeschränkte Verwendung
INA
• INA uses near real-time data that includes real
network statistics, up-to-date topology and
routing information across all network layers.
• INA simulates topology changes and their
impact on data traffic and latency.
• Complex root-cause and impact analyses can
be applied at any granularity, including
subnetwork, site and individual devices down
to a single port.
SIMULATION BASED PLANNING
INA as digital twin represents the as is E2E
network and simulates planned network changes.

C2 - Eingeschränkte Verwendung
INA
A new link should be added in order to
decrease the utilization on the
overloaded red link
If the link is inserted at this point, an
overload will occur at a new point.
SIMULATION BASED PLANNING
This location for the new link is
suitable as the traffic now runs via
different routes and thus no longer
causes congestion

INA
TROUBLESHOOTING
INA: In case of an outage, not only directly
connected antennas can be identified, but also
wider effects on the network are easy to discover
• Impact Analysis is easily possible to conduct
- Identification of impacted sites
- Consideration of all routed traffic
- identification of all dependent antennas
• Use cases: Power outages, malfunctioning
network elements, environmental influences,
sabotage
• INA interfaces with ticketing systems and can
correlate to actual incidents or changes in near
real time.

PREDICTIVE MAINTANANCE
INA tests the robustness of the network without
your help. And helps to combat neuralgic points.
• A virtual network engineer (Chaos Monkey)
will run continuously in the background and
randomly simulate failures by consecutively
switching points in the network on and off.
• This will identify sensitive/neuralgic points in
the network. Similarly, the extent of the
damage and the impact on other parts of the
network will be revealed.

Simulated Annealing
• If you would want to assign the antenna to a
yellow backbone router through the blue
routers so that utilization is minimized.
• There are 800bn possible combinations:
517
= 800bn
• Brute force calculation of all combinations
would take ~25 years if we assume 1ms per
configuration.
• INA’s Annealer feature automatically analyses
possible routing options and suggests the best
option within the tested range.
• Simulated Annealing finds optimized solution
within 60 s after 1000 tested combinations.
AUTOMATED ROUTING OPTIMIZATION

C2 - Eingeschränkte Verwendung
INA
A non optimal routing is selected. The
Annealer starts to test other routing
configurations (1000 combinations
within 60s).
The annealer proposes an optimized
routing configuration next to the
input configuration for better
comparison. A data table describes
the proposed changes.

SUSTAINABILITY
Make the network more
sustainable by discovering
particularly energy-
intensive components,
and reduce CO2
consumption in the entire
network
SECURITY
Detection of neuralgic
points in the network,
which e.g. supply large
parts of the population or
critical infrastructures
FUTURE NETWORK
Change analysis,
simulation and planning
to verify network changes
before they are applied to
the network
PREDICTIVE
MAINTANANCE Avoid
network outages and
misconfigurations as
mismatches will be
detected beforehand
COVERAGE
Measure network
coverage and evaluate
options to reach the
expansion targets and
increase service quality
Model further,
individualized cases and
find answers to questions
as you need them when
you need them
INA‘s potential
for the whole
telecom
business.
INA's technology allows users to combine data points that help to answer very
specific questions in a variety of use cases. In addition, INA offers ready-made use
cases, as well as the possibility to jointly develop even more.
SUSTAINABILITY
Discover particularly
energy-intensive
components, and reduce
CO2 consumption in the
entire network
