T-MANO & Counting: SKT's New NFV Platform

The complexities of management and orchestration (MANO) have seen many telco executives figuratively tearing out their hair in frustration as they try to virtualize their companies' networks.

Interoperability, of course, has been the main bugbear. Until recently, South Korea's SK Telecom (Nasdaq: SKM) had been forced to maintain separate MANO platforms for each NFV supplier it was using. Despite vendor assurances on "open interfaces," product specifications have differed from one vendor to another, says the telco. But supporting a multitude of MANO platforms means adding to the complexity and cost. Virtualization is supposed to be about the opposite.

Enter T-MANO. The new platform, which SK Telecom unveiled earlier today, is intended to work with any vendor's products. That means SK Telecom can dump its older platforms and manage its virtualized networks more efficiently. From now on, when it wants to launch a new service, it will be able to set up the requisite systems in one go instead of handling each and every system separately. (See SK Telecom Commercializes T-MANO.)

That is the promise, anyway. But SK Telecom has enough confidence in T-MANO to have trumpeted some concrete virtualization targets in connection with the move. T-MANO will first be used to support all virtualized VoLTE routers, says the operator, before it is expanded to cover virtualized evolved packet core (EPC) and additional equipment. This year, SK Telecom's aim is to ensure that virtualized EPC accounts for 80% of all newly deployed EPC equipment. From 2019, it says, it will only deploy vEPC.

SK Telecom also plans to release T-MANO's application programming interfaces (APIs) into the broader community. As a result, it says, anyone will be able to integrate T-MANO code into virtualized network functions or software.

The move, clearly, is not dissimilar to AT&T Inc. (NYSE: T)'s decision to make its ECOMP software platform available to others through the Linux Foundation. Now combined with the Foundation-led OPEN-O initiative to form ONAP, that platform has already won support from a number of vendors as well as telcos, including France's Orange (NYSE: FTE), BCE Inc. (Bell Canada) (NYSE/Toronto: BCE), Russia's VEON and China's three national carriers -- China Mobile Ltd. (NYSE: CHL), China Telecom Corp. Ltd. (NYSE: CHA) and China Unicom Ltd. (NYSE: CHU). (See Big Names Board the ONAP Express.)

ONAP's big rival thus far has been the Open Source MANO Community (OSM) initiative backed by the European Telecommunications Standards Institute (ETSI) and featuring some equally high-profile names, including the UK's BT Group plc (NYSE: BT; London: BTA), Norway's Telenor ASA (Nasdaq: TELN), Spain's Telefónica and Sprint Corp. (NYSE: S) in the US. SK Telecom is also an OSM participant and stuck to ETSI specifications when designing the T-MANO platform, it says.

It is perhaps too early to say what T-MANO means, if anything, for MANO more generally. What is clear is that, despite the recent consolidation in this space, there is still concern about a bifurcation of industry efforts. The global market needs a single approach, say critics, if it is to overcome the enormous challenges it faces. Designed to curtail complexity, new platforms and initiatives could inadvertently exacerbate it.

Re: Work with any vendor product?
SK Telecom's PR firm informs me that they have achieved interoperability with one (unnamed) vendor currently and are planning to expand to 4-5 by the end of the year. I'd guess that first vendor is HPE (whose NFV Director is used as SK Telecom's T-OVEN orchestrator) not Netcracker, Aloke.

Work with any vendor product?
Can Light Reading share more details on this aspect as to how can SKT's T-MANO work with any vendor product? Which vendors are involved in the current interoperability puzzle that is solved?

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.
