DT Unveils New Network Vision

LONDON -- Deutsche Telekom AG (NYSE: DT) today unveiled a new vision of how it intends to cast off the shackles of cumbersome traditional networking operations and adopt a new model -- the TeraStream Architecture -- that takes its inspiration from the cloud.

Speaking on Tuesday at the Cloud-Net Summit in London, Axel Clauberg, DT's vice president of IP Architecture and Design, said that greater simplicity was needed in telecom operator networks. "We are very good at exploring new opportunities but have problems in bringing new ideas to market due to the complexity of our networks."

He added: "We are still running many old technologies" such as ATM, frame relay, and so on, "while having to add new ones too, such as IPv6. We have to simplify."

Clauberg said the evolution of cloud services has provided the inspiration for DT's new network template. "Cloud services can help us redesign our services delivery architecture, and we have designed a new, simplified model called the TeraStream Architecture," a native IP network designed around the cloud model of flexible asset control.

The new architecture has a very simple topology with the minimal number of network elements, comprising an optical ring backbone interspersed with just two types of routers that link to data centers and access networks. The architecture would offer end-to-end IP connections and be designed as a native IPv6 network.

The applications and tools needed to actually run the network and deliver services would largely be housed in the data centers: "We would use the cloud services paradigm for our service delivery," said Clauberg.

A big issue for DT to sort out is its Service Provider Information Technology (SPIT) set-up, particularly its OSS capabilities. "There are a lot of legacy issues with OSS -- it's often the major cause of delays in bringing new services to market," noted Clauberg, adding that DT is planning to build a "new real-time OSS to overcome" these issues.

The OSS layer would be the glue between the network and the service capabilities housed in the data center, leading DT towards a more software-defined networking (SDN) model whereby the network can become a programmable entity that can be managed centrally. To this end, Clauberg sees a role for the OpenFlow SDN protocol that has stirred quite a bit of controversy in the industry in the past year. (See It's Open Season for OpenFlow, OpenFlow Slices Up the Network, OpenFlow's 'Centralized' Problem and Cisco Will Support OpenFlow.)

However, he doesn't envisage SDN as an end-to-end networking possibility. Instead he sees a role for OpenFlow in the data center and in the access network but not in the core, where the public Internet's BGP (border gateway protocol) "won't disappear," making SDN in the core a theoretical possibility but not something the DT man believes is workable.

Where SDN does work, though, DT is pushing ahead to create more manageable and flexible networking environments, and Clauberg said that OpenFlow would be used in a customer trial before the end of 2012.

Whatever the protocol or the networking philosophy, Clauberg knows that DT needs to move towards its TeraStream Architecture vision without delay. "To be profitable we need to simplify and the cloud model can help us achieve this." He believes the new model can deliver cost, service and innovation leadership for DT and enable it to achieve real and full fixed and mobile network integration.

re: DT Unveils New Network Vision


well we'll see if this really turns out as a sustainable and affordable strategy, in particular when it comes to migrate the installed base, the associated services and customer base and - not to forget to get the buy-in of DT's different OPCOs.

re: DT Unveils New Network Vision


All good points, RudiW.


It's an interesting vision and like other similar ideas around simplified networks with greater flexibility and lower opex it's more likely to inform future developments rather then be a hard and fast blueprint (bearing in mind, of course, that the topology and detail presented wil have been greatly simplified to get across the genral idea).


 


The question for me -- and this applies generally and not just for this DT vision -- is what form the 'data center' will take in comms service provider architectures in the future.


A small number of super data centers per (regulatory) market?


Or a large number of local data centers (maybe utilizing current central office real estate)?


Or a very small number of large data centers supplemented by regional/metro centers?


 


Local content caching requirements that will require some sort of local server cluster presence would tend to lend themselves towards the latter model but...


ANy thoughts?

So it take it DT did not provide a timeline for the transformation. I wonder if at this point this is just a vision or whether DT has a blueprint of how this vision will take shape. Still, it will be most interesting to watch if DT unveils further details.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
