OPNFV's releases reflect the evolving needs of the telcos

The Open Platform for NFV (OPNFV) is increasingly focused on supporting cloud-native technologies and the network edge.

Heather KirkseyThe open source group, part of the Linux Foundation, specialises in the system integration of network functions virtualisation (NFV) technology.

The OPNFV issued Fraser, its latest platform release, earlier this year while its next release, Gambia, is expected soon.  

Moreover, the telcos continual need for new features and capabilities means the OPNFV’s work is not slowing down.

“I don’t see us entering maintenance-mode anytime soon,” says Heather Kirksey, vice president, community and ecosystem development, The Linux Foundation and executive director, OPNFV.

ONF advances its vision for the network edge

The Open Networking Foundation’s (ONF) goal to create software-driven architectures for the network edge has advanced with the announcement of its first reference designs.

In March, eight leading service providers within the ONF - AT&T, Comcast, China Unicom, Deutsche Telekom, Google, NTT Group, Telefonica and Turk Telekom - published their strategic plan whereby they would take a hands-on approach to the design of their networks after becoming frustrated with what they perceived as foot-dragging by the systems vendors.  

Timon SloaneThree months on, the service providers have initial drafts of the the first four reference designs: a broadband access architecture, a spine-leaf switch for network functions virtualisation (NFV), a more general networking fabric that uses the P4 packet forwarding programming language, and the open disaggregated transport network (ODTN).  

The ONF also announced four system vendors - Adtran, Dell EMC, Edgecore Networks, and Juniper Networks - have joined to work with the operators on the reference design programmes.

What the cable operators are planning for NFV and SDN

Cable operators may be quieter than the telecom operators about network functions virtualisation (NFV) and software-defined networking (SDN) but what they are planning is no less ambitious.

Cable operators are working on adding wireless to their fixed access networks using NFV and SDN technologies.

Don Clarke“Cable operators are now every bit as informed about NFV and SDN as the telcos are, but they are not out there talking too much about it,” says Don Clarke, principal architect for network technologies at CableLabs, the R&D organisation serving the cable operators.

Clarke is well placed to comment. While at BT, he initiated the industry collaboration on NFV and edited the original white paper which introduced the NFV concept and outlined the operators’ vision for NFV.

Verizon's move to become a digital service provider

Verizon’s next-generation network based on network functions virtualisation (NFV) and software-defined networking (SDN) is rapidly taking shape.

Working with Dell, Big Switch Networks and Red Hat, the US telco announced in April it had already brought online five data centres. Since then it has deployed more sites but is not saying how many.

“We are laying the foundation of the programmable infrastructure that will allow us to do all the automation, virtualisation and the software-defining we want to do on top of that,” says Chris Emmons, director, network infrastructure planning at Verizon.

Ciena offers enterprises vNF pick and choose

Ciena, working with partners, has developed a platform for service providers to offer enterprises network functions they can select and configure with the click of a button.

Dubbed Agility Matrix, the product enables enterprises to choose their IT and connectivity services using software running on servers. It also promises to benefit service providers' revenues, enabling more adventurous service offerings due to the flexibility and new business models the virtual network functions (vNFs) enable. Currently, managed services require specialist equipment and on-site engineering visits for their set-up and management, while the contracts tend to be lengthy and inflexible.
