TIP launches a disaggregated cell-site gateway design

Part 1: TIP white-box designs

Four leading telecom operators, members of the Telecom Infra Project (TIP), have developed a disaggregated white-box design for cell sites. The four operators are Orange, Telefonica, TIM Brazil and Vodafone. BT is also believed to be backing the open-design cell-site venture.

The first TIP cell-site gateway product, known as Odyssey-DCSG, is being brought to market by ADVA and Edgecore Networks.

TIP isn’t the only open design framework that is developing cell-site gateways. Edgecore Networks contributed in October a design to the Open Compute Project (OCP) that is based on an AT&T cell-site gateway specification. There are thus two overlapping open networking initiatives developing disaggregated cell-site gateways. 

ADVA and Edgecore will provide the standardised cell-site gateways as operators deploy 5G. The platforms will support either commercial cell-site gateway software or open-source code.

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.

NeoPhotonics samples its first CFP-DCO products

NeoPhotonics has entered the fray as a supplier of long-distance CFP pluggable modules that integrate the coherent DSP-ASIC chip with the optics. 

The company has announced two such CFP Digital Coherent Optics (CFP-DCO) modules: a 100 gigabit-per-second (Gbps) module and a dual-rate 100Gbps and 200Gbps one.

“Our rationale [for entering the CFP-DCO market] is we have all the optical components and the [merchant coherent] DSPs are now becoming available,” says Ferris Lipscomb (pictured), vice president of marketing at NeoPhotonics. “It is possible to make this product without developing your own custom DSP, with all the expense that entails.”

The white box concept gets embraced at the optical layer

Lumentum has unveiled several optical white-box designs. To date the adoption of white boxes - pizza-box sized platforms used in large-scale data centres - has been at the electronic layer, for switching and routing applications.

Brandon Collings

White boxes have arisen to satisfy the data centre operators’ need for simple building-block functions in large number that they can direct themselves.  

“They [data centre operators] started using very simple white boxes - rather simple functionality, much simpler than the large router companies were providing - which they controlled themselves using software-defined networking orchestrators,” says Brandon Collings, CTO of Lumentum.

Cyan's stackable optical rack for data centre interconnent

Demand for high-capacity links between data centres is creating a new class of stackable optical platform from equipment makers. Cyan has unveiled the N-Series, what it calls an open hyperscale transport platform. "It is a hardware and software system specifically for data centre interconnect," says Joe Cumello, Cyan's chief marketing officer. Cyan's announcement follows on from Infinera, which detailed its Cloud Xpress platform last year.

"The drivers for these [data centre] guys every day of the week is lowest cost-per-gigabit"

WDM and 100G: A Q&A with Infonetics' Andrew Schmitt

The WDM optical networking market grew 8 percent year-on-year, with spending on 100 Gigabit now accounting for a fifth of the WDM market. So claims the first quarter 2014 optical networking report from market research firm, Infonetics Research. Overall, the optical networking market declined 2 percent, due to the continuing decline of legacy SONET/SDH.

In a Q&A with Gazettabyte, Andrew Schmitt, principal analyst for optical at Infonetics Research, talks about the report's findings.

Q: Overall WDM optical spending was up 8% year-on-year: Is that in line with expectations?

AS: It is roughly in line with the figures I use for trend growth but what is surprising is how there is no longer a fourth quarter capital expenditure flush in North America followed by a down year in the first quarter. This still happens in EMEA but spending in North America, particularly by the Tier-1 operators, is now less tied to calendar spending and more towards specific project timelines.

This has always been the case at the more competitive carriers. A good example of this was the big order Infinera got in Q1, 2014.
