Time is a common good, yet hardly any thought is given to its handling or its synchronisation in particular.
Time synchronisation is used in various areas: from own networks to trading transactions in the financial sector. Depending on the type of application, it requires high accuracy.
Today's solutions are mostly based on satellites (e.g. GNSS, GPS) and therefore exposed to various risks, including hacker attacks or technical problems. Synchronisation information can be provided in various ways and different standards though.
New application areas such as 5G and edge cloud evolution are creating additional drivers and requirements for highly accurate time.
Based on the company's history, Deutsche Telekom has its own synchronisation network, which can be operated independently of GNSS systems. We would like to give a brief insight into the history of time synchronisation and its use cases.

I have been with Deutsche Telekom since January 2002. I worked my way through the 24/7 shift NOC, last-level support and configurations to engineering for AS3320. In 2019, after developing configurations and improving our BGP policy for AS3320, as well as taking on the role of Juniper Systems Engineer for our backbone, I took the next step and took on a role in product management. And here I am, the one and only Peering Manager for AS3320.

In 2007, I joined Telekom as a product manager. In the national wholesale business, I was responsible for value added services. Over the years I was able to expand my know-how in the areas of voice interconnection and fibre access. Since 2022, I have been working for Telekom Global Carrier in the area of Internet and Content. My focus is on IP transit and especially TimeSynchronisation.
