The ONF adapts after sale of spin-off Ananki to Intel

Intel’s acquisition of Ananki, a private 5G networking company set up within the ONF last year, has meant the open-model organisation has lost the bulk of its engineering staff.

Timon Sloane

The ONF, a decade-old non-profit consortium led by the telecom operators, has developed some notable networking projects over the years such as CORD, OpenFlow, one of the first software-defined networking (SDN) standards, and Aether, the 5G edge platform.

Its joint work with the operators has led to virtualised and SDN building blocks that, when combined, can address comprehensive networking tasks such as 5G, wireline broadband and private wireless networks.

The ONF’s approach has differed from other open-source organisations. Its members pay for an in-house engineering team to co-develop networking blocks based on disaggregation, SDN and cloud.

The ONF and its members have built a comprehensive portfolio of networking functions which last year led to the organisation spinning out a start-up, Ananki, to commercialise a complete private end-to-end wireless network.

Now Intel has acquired Ananki, taking with it 44 of the ONF’s 55 staff.

“Intel acquired Ananki, Intel did not acquire the ONF,” says Timon Sloane, the ONF’s newly appointed general manager. “The ONF is still whole.”

The ONF will now continue with a model akin to other open-source organisations.

Access 4.0: A valuable lesson in network transformation

The Access 4.0 broadband deployment by Deutsche Telekom has deepened its understanding of the intricacies of network transformation. The Access 4.0 team discusses what it has learnt and reflects on the issues a mass deployment raises.

Deutsche Telekom’s Access 4.0 platform has been delivering broadband services for nearly half a year.

But the operator has deliberately limited the deployment of the next-generation fibre-to-the-x platform to one central office in Stuttgart.

Robert SoukupThe system is fully functional, says Robert Soukup, senior program manager at Deutsche Telekom, but the operator wants to understand the processes involved so they can be automated before it starts the widescale deployment.

“Now we can see where the gaps are and what we need to adapt internally,” says Hans-Jörg Kolbe, chief engineer and head of SuperSquad Access 4.0 at Deutsche Telekom.

This will take the rest of the year. Only if this final check is successful will the Access 4.0 platform be rolled out across the operator’s 1,000 central offices in Germany.

Deutsche Telekom's Access 4.0 transforms the network edge

Deutsche Telekom has a working software platform for its Access 4.0 architecture that will start delivering passive optical network (PON) services to German customers later this year. The architecture will also serve as a blueprint for future edge services. 

Hans-Jörg Kolbe

Access 4.0 is a disaggregated design comprising open-source software and platforms that use merchant chips - ‘white-boxes’ - to deliver fibre-to-the-home (FTTH) and fibre-to-the-building (FTTB) services. 

“One year ago we had it all as prototypes plugged together to see if it works,” says Hans-Jörg Kolbe, chief engineer and head of SuperSquad Access 4.0. “Since the end of 2019, our target software platform – a first end-to-end system - is up and running.”

ONF’s published reference designs start to be deployed

Operators are already deploying the first reference designs published by the Open Networking Foundation (ONF). Three of the ONF’s five reference designs have now been made public. 

Just over a year ago, eight operators - AT&T, Comcast, China Unicom, Deutsche Telekom, Google, NTT Group, Telefonica and Turk Telekom - took the step to design key components of their edge and access networks after becoming frustrated with what they perceived as foot-dragging by the systems vendors.  

AT&T is deploying one of the reference designs - the SDN-enabled broadband access scheme (SEBA). Deutsche Telekom and Telefónica have also said they will deploy SEBA during 2019 and 2020.

Edgecore exploits telecom’s open-networking opportunity

Part 2: Open networking

Edgecore Networks is expanding its open networking portfolio with cell-site gateways and passive optical networking (PON) platforms. 

The company is backing two cell-site gateway designs that aggregate traffic from baseband units for 4G and 5G mobile networks. One design is from the Open Compute Project (OCP) that is available now and the second is from the Telecom Infra Project (TIP) that is planned for 2019 (see table).

Edgecore has also announced PON optical line terminal (OLT) platforms addressing 10-gigabit XGS-PON and GPON.
