DT's Pan-Net Still at Start of the Marathon

When Deutsche Telekom fired the starting gun on its pan-European network project in early 2015, the task ahead of the German incumbent looked daunting. (See Deutsche Telekom Turns On Pan-European IP.)

The overarching goal for the project -- today shortened to "pan-net" -- was to replace the network facilities in specific countries with systems that could address the entire region. Instead of developing products for each of the countries in its footprint, Deutsche Telekom AG (NYSE: DT) would then be able to rely on a single, centralized platform serving all of its European customers, from Germany in the north to Greece in the south.

The overhaul promised cost savings of about €1.2 billion ($1.4 billion, at today's exchange rate) by 2020, according to Claudia Nemat, Deutsche Telekom's head of technology and innovation, including about €500 million ($567 million) from outside Germany. Of that, Nemat said she was expecting to see about €200 million ($228 million) in savings from the harmonization of platforms and lower spending on vendors, another €200 million ($228 million) from the simplification of technical services and about €50 million ($57 million) from the related shutdown of the old-fashioned public switched telephony network.

More importantly, by taking advantage of new software and virtualization technologies, Deutsche Telekom hoped to speed up service development and acquire some of the "fail fast" abilities of its over-the-top challengers. During pan-net trials in Croatia, the operator claimed to have set up a virtual private network "of medium complexity" in as little as 15 minutes. Using old-fashioned approaches, that process can take up to four weeks, said Nemat.

But getting a company of Deutsche Telekom's size to embrace unproven technologies, and a radically different modus operandi, was never going to happen overnight. "I compared this journey to a marathon in the past, and we are still in the first kilometers of the marathon," says Axel Clauberg, Deutsche Telekom's vice president of aggregation, transport and IP architecture.

That partly reflects the immaturity of the software and virtualization technologies that underpin the pan-net, not to mention some disappointment with industry progress in these areas so far. "It is not directly related to pan-net, but we had expected the industry to move a bit faster toward cloud-native technologies," says Clauberg. "That has not been an easy change for suppliers."

Nevertheless, while Deutsche Telekom might still be near the beginning of what is going to be a very long race, it has taken some important first steps. These include the opening of a data center in Hungary, which is essentially Deutsche Telekom's first centralized production facility, as well as a service operations center in Romania that is staffed around the clock. A second data center is due to open in Poland in the coming months, although the operator will not say exactly when.

Any word on...? Has the slower-than-expected progress also affected DT's Zero Touch Network & Service Management initiative? Announced with some fanfare in March, as a 3-month 15-vendor collaboration but pretty much radio silence since...
