The Blue Planet platform's ongoing automation journey

Vodafone UK is one operator that has recently chosen Ciena's Blue Planet for the management of its optical and IP networks. An interview with Ciena to understand what the Blue Planet network automation tool does.

Having some knowledge of a telco's operations helps in understanding the role of a network automation platform. So says Kevin Wade, senior director and product marketing team leader at Ciena Blue Planet.

Service providers, like any business, have an operational infrastructure that begins with business processes. For a service provider, the process starts with a connectivity service request. The business processes capture the customer's order and deliver the requested service.

Once up and running, the service must be monitored and managed to ensure the service level agreement is upheld.

"Today, these processes are highly manual," says Wade. "Automation is being looked at and deployed more extensively to simplify these processes."

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.

How ONAP is blurring network boundaries

Telecom operators will soon be able to expand their networks by running virtualised network functions in the public cloud. This follows work by Amdocs to port the open-source Open Network Automation Platform (ONAP) onto Microsoft’s Azure cloud service.

According to Craig Sinasac, network product business unit manager at Amdocs, several telecom operators are planning to run telecom applications on the Azure platform, and the software and services company is already working with one service provider to prepare the first trial of the technology.    

Deploying ONAP in the public cloud blurs the normal understanding of what comprises an operator’s network. The development also offers the prospect of web-scale players delivering telecom services using ONAP.

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.

ETSI embraces AI to address rising network complexity

The growing complexity of networks is forcing telecom operators and systems vendors to turn to machine intelligence for help. It has led the European Telecommunications Standards Institute, ETSI, to set up an industry specification group to define how artificial intelligence (AI) can be applied to networking.

 “With the advent of network functions virtualisation and software-defined networking, we can see the eventuality that network management is going to get very much more complicated,” says Ray Forbes, convenor of the ETSI Industry Specification Group, Experimental Network Intelligence (ISG-ENI).

The AI will not just help with network management, he says, but also with the introduction of services and the more efficient use of network resources.

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.
