About Magenta Telekom
Magenta Telekom (T-Mobile Austria GmbH) is one of
the leading telecommunications providers in Austria.
With around 2,200 employees, the company generated
revenue of around EUR 1.35 billion in 2021. As part ofthe Deutsche Telekom group, it benefits from theinnovative strength and financial stability of the group,
one of the largest players in the global market ofTelekom. Magenta Telekom offers customers ultrafast
broadband via fiber optic cable and coaxial cable, as
well as mobile communications, business solutions,entertainment, and the latest technology for digital life.
The Austrian provider also acts as a center of excellence
for the entire Deutsche Telekom group in all areas,
including the internet of things (IoT).

The challenge was to restructure thetraffic while still estimating the totalvolume correctly.

Business Challenge
Magenta Telekom uses a hardware-based monitoring
solution for nationwide monitoring of network
availability and analyzing sources of errors. However,increasingly powerful systems are needed to ensure
the quality and performance of fourthand fifthgeneration mobile networks. They need to be able tohandle the rapid increase in user traffic.
This is not an easy task: The volume of network traffic
in mobile communications is increasing exponentiallyeach year. This makes it more important for Magenta
Telekom to continue to ensure the high quality and© 2023 Gigamon. All rights reserved.

availability level of the networks. This task can no longer
be accomplished without measurement and analysis
platforms specifically geared to today’s data volumes
and transmission rates.
It was therefore necessary to expand the existing
monitoring solution with a solution that also enables themonitoring of 4G and 5G data traffic. For this purpose,
Magenta Telekom specifically looked for a system thatanalyzes modern mobile connections and sounds
an alarm at an early stage when line or performance
problems occur.

Resolution
Maximum performance and security across the entire
supply network — that is Magenta Telekom´s maxim.
To ensure this in the future, magellan netzwerke
installed a powerful next-generation network packet
brokering solution for managing and monitoring bothcontrol and data traffic.
To monitor and secure the network at Magenta Telekom
according to the latest standards, the magellan DANT
(Data Access and Network Telemetry) team drew
up a rough and detailed plan for the systems anddeployment scenarios in question. The experts thenimplemented the Gigamon Deep Observability Pipeline,
for acquiring and aggregating control and data traffic
across Magenta Telekom’s entire mobile coveragearea. The latest-generation of the Gigamon Deep
Observability Pipeline can also monitor 4G and 5G data
traffic based on real-time applications while at the sametime guaranteeing performance and ensuring efficienttraffic management with load-balancing in the corenetwork.
For this purpose, they can correlate GTP (GPRS
Tunnelling Protocol) user traffic. This function was
not available in the hardware previously used, which
was one of the decisive reasons for upgrading
the monitoring solution. At the time of project
implementation, GTP correlation (including 5G andCUPS) technology was relatively new on the market,
so Magenta Telekom and magellan netzwerke wereconsidered real pioneers in this field.

About Magellan Netzwerke Gmbh
Our network capacities are constantlygrowing. That’s why we are glad to havemagellan supporting us to expand theinfrastructure.”

When implementing the new solution, the experts
from magellan netzwerke had to carry out detailed prefiltering. This was because the monitoring system hadgrown historically in such a way that a redistribution of
the data flows across the Gigamon Deep Observability
Pipeline components was necessary.

BenefitToday, Magenta Telekom is equipped with a highly
available monitoring solution that provides realtime
performance analysis and seamless reporting on
mobile and broadband network activities.

magellan netzwerke GmbH was founded on April 1,
1992, in Cologne and now employs over 280 people
in ten locations. Since 2016, magellan has also been
a company of the FERNAO Networks group ofcompanies, which combines the know how of several
successful IT companies. magellan’s expertise is broadly
diversified and includes key topics such as IT security,
IT infrastructure, monitoring and data analytics, cloudand data center solutions and managed services. Moreinformation: magellan-net.de.
