Infinera buying Coriant will bring welcome consolidation  

Infinera is to purchase privately-held Coriant for $430 million. The deal will effectively double Infinera’s revenues, add 100 new customers and expand the systems vendor’s product portfolio.

Infinera's CEO, Tom FallonBut industry analysts, while welcoming the consolidation among optical systems suppliers, highlight the challenges Infinera faces making the Coriant acquisition a success.   

“The low price reflects that this isn't the best asset on the market,” says Sterling Perrin, principal analyst, optical networking and transport at Heavy Reading. “They are buying $1 of revenue for 50 cents; the price reflects the challenges.”

ONF’s operators seize control of their networking needs

  • The eight ONF service providers will develop reference designs addressing the network edge.
  • The service providers want to spur the deployment of open-source designs after becoming frustrated with the systems vendors failing to deliver what they need. 
  • The reference designs will be up and running before year-end.
  • New partners have committed to join since the consortium announced its strategic plan

The service providers leading the Open Networking Foundation (ONF) will publish open designs to address next-generation networking needs.

Timon SloaneThe ONF service providers - NTT Group, AT&T, Telefonica, Deutsche Telekom, Comcast, China Unicom, Turk Telekom and Google - are taking a hands-on approach to the design of their networks after becoming frustrated with what they perceive as foot-dragging by the systems vendors.

“All eight [operators] have come together to say in unison that they are going to work inside the ONF to craft explicit plans - blueprints - for the industry for how to deploy open-source-based solutions,” says Timon Sloane, vice president of marketing and ecosystem at the ONF.

Ciena picks ONAP’s policy code to enhance Blue Planet  

Ciena is adding policy software from the Linux Foundation’s open-source Open Network Automation Platform (ONAP) to its Blue Planet network management platform.

Operators want to use automation to help tackle the growing complexity and cost of operating their networks.

Kevin Wade“Policy plays a key role in this goal by enabling the creation and administration of rules that automatically modify the network’s behaviour,” says Kevin Wade, senior director of solutions, Ciena’s Blue Planet. 

Incorporating ONAP code to enhance Blue Planet’s policy engine also advances Ciena’s own vision of the adaptive network.

China Mobile plots 400 Gigabit trials in 2017

China Mobile is preparing to trial 400-gigabit transmission in the backbone of its optical network in 2017. The planned trials were detailed during a keynote talk given by Jiajin Gao, deputy general manager at China Mobile Technology, at the OIDA Executive Forum, an OSA event hosted at OFC, held in Los Angeles last week.

The world's largest operator will trial two 400-gigabit variants: polarisation-multiplexed, quadrature phase-shift keying (PM-QPSK) and 16-ary quadrature amplitude modulation (PM-16QAM).

What role FPGA server co-processors for virtual routing?

Part 2:  Accelerating virtual routing functions using FPGAs

IP routing specialists have announced first virtual edge router products that run on servers. These include Alcatel-Lucent with its Virtualized Service Router and Juniper with its vMX. Gazettabyte asked Alcatel-Lucent's Steve Vogelsang about the impact FPGA accelerator cards could have on IP routing.


Steve Vogelsang, IP routing and transport CTO, Alcatel-Lucent

The co-processor cards in servers could become interesting for software-defined networking (SDN) and network function virtualisation (NFV).

The main challenge is that we require that our virtualised network functions (vNFs) and SDN data plane can run on any cloud infrastructure; we can’t assume that any specific accelerator card is installed. That makes it a challenge.

SDN starts to fulfill its network optimisation promise 

Infinera, Brocade and ESnet demonstrate the use of software-defined networking to provision and optimise traffic across several networking layers.

Infinera, Brocade and network operator ESnet are claiming a first in demonstrating software-defined networking (SDN) performing network provisioning and optimisation using platforms from more than one vendor.

Mike Capuano, Infinera

The latest collaboration is one of several involving optical vendors that are working to extend SDN to the WAN. ADVA Optical Networking and IBM are working to use SDN to connect data centres, while Ciena and partners have created a test bed to develop SDN technology for the WAN.
