pnos 320Telcos are shy about telling the public but some are moving from "trials" to deployment. British Telecom told analysts they are about to finish their 25,000 "trial" and move forward with deploying 10M lines of Calix has a half-dozen customers in "deployment." Geoff Burke wanted to tell me more, but his customers aren't ready. Windstream is their first announced customer and has ordered gigabit class bonded equipment. Calix sells to all the U.S. companies. They recently had a proud moment when Verizon chose their 40 gigabit NG-PON2 over Nokia Alcatel. They lead the market in the 4,000 or so small U.S. telcos. Working with Ericsson, they also sell around the world. They were considered by Australia's National Broadband Network a while back. Geoff wouldn't even give me a hint off the record which companies he was discussing. 

Calix believes their SDN platform AXOS  is helping them win accounts.

This from their financial call is now superseded: "I am pleased to report that our growth in AXOS is accelerating and our AXOS platform is now deployed in over 50 service providers." As I was about to post this article, a release from Calix said they were over 100 users. (Below.) While AXOS is proprietary, Calix is contributing to ONOS, the open source SDN controller.  ONOS is now a project of the Linux Foundation, spearheaded by a large team of AT&T engineers. But even a $200B telco is strained to come up with the resources to develop a complete SDN system.  

Adtran's Tom Stanton, also bringing a proprietary SDN to market, believes most telcos are following AT&T and moving their SDN/NFV efforts to ONOS and CORD or something very similar. It's easy for me to project that most SDN software will migrate to the Open Source standard and YANG/Netconf. ONOS and CORD are designed to work with others, with well-defined "Northbound" and "Southbound" interfaces. The interconnected software, ranging from device drivers to massive systems, can remain proprietary so companies can protect their "secret sauce." 

Bill Bittancourt is also enthusiastic about Calix's work on over coax. The thicker cables provide longer and more reliable reach. Lab testing points to 750/750 speeds. My first thought was most coax already has cable TV and broadband running, but Bill is finding numerous prospects. DirecTV, now part of AT&T, reportedly installed millions of coax connections to distribute satellite TV and apparently there's coax available elsewhere.

ONOS Project and ONF open-source a DataCenter Leaf-Spine Fabric built with Bare Metal switches and Classic SDN control

July 21, 2016

The combination of the following three key attributes makes the DC Fabric unique offering big value to developers and network operators:

  • use of state-of-the-art bare-metal (white-box) switching hardware (e.g., switches from Edge-core Networks with Broadcom ASICs)
  • use of classic SDN architecture with special emphasis on
    •       control-plane that provides HA/scale/performance using an ONOS cluster, and
    •       data-plane scale using OpenFlow 1.3 that exploits multi-table and port-group support of the switching silicon
  • use of completely open-source software everywhere
    •       for the control plane: ONOS + fabric-control application, and
    •       for the data plane switch software: ONL + OF-DPA + Indigo

The advantages of Classic SDN, Bare-metal switches and open source are big compared to existing solutions with traditional networking: (1) simpler and more flexible control; (2) ability to rapidly introduce new features and customized functionality; (3) no vendor lock-in leading to significantly lower Total Cost of Ownership (TCO). Furthermore, an integrated, complete, open-source solution eliminates commercial licenses while leveraging contributions from a growing open-source community.

Introducing Trellis: DC Fabric Underlay + Virtual Network Overlay + Unified SDN Control

The first open-source DC network infrastructure of its kind that

  • combines an underlay leaf-spine fabric with a virtual network overlay, and
  • leverages unified SDN control over both underlay and overlay networks

Common SDN control over underlay and overlay networks enable simple, efficient implementations of

  • Distributed Virtual Routing for tenant networks
  • Optimized delivery of Multicast traffic streams
  • and many more resource optimizations as well as new capabilities (to be demonstrated in near future)

Trellis has been demonstrated as the enabling network infrastructure for CORD

Trellis has been an important component of the CORD platform and has been demonstrated as part of various CORD POCs and will rapidly evolve with the CORD platform and its various domains of use.

Award-Winning Calix AXOS Platform Storms Past 100 Service Provider Mark

Company That Created Software Defined Access Uses AXOS to Enable Market Disruptors

PETALUMA, CA--(Marketwired - September 01, 2016) - Calix, Inc. (NYSE: CALX), the world leader in enabling next generation service delivery with an unmatched subscriber experience, today announced its award-winning AXOS platform is gaining unprecedented rapid adoption and network deployment at over 100 service providers around the world.

Fueling this momentum, Calix has demonstrated the power of AXOS to speed innovation and service delivery with a rapid expansion of its solutions portfolio. Shortly after introducing the portfolio, Calix became the first company to deliver a commercially available bonded solution -- capable of over one gigabit per second downstream over copper -- thereby bringing a gigabit experience to previously underserved subscribers in multiple dwelling units (MDUs). Traditionally, with lab tests, certifications and OSS/IT integration, it would take a typical service provider 12 to 15 months to introduce a new technology like into its network, but AXOS has allowed Calix customers to quickly move to full commercial deployments in a fraction of the time. Today, Calix customers are delivering enabled services to thousands of subscribers over existing in-building copper and coaxial infrastructure, and tapping into the MDU opportunity with an unmatched subscriber experience.

In late 2015, Calix made headlines in the communications industry with its launch of a Software Defined Access networking framework and AXOS operating system. A few months later, Calix received the 2016 Light Reading Leading Lights award for "Most Innovative SDN Product Strategy (Vendor)" and was recognized as the first company to launch a Software Defined Access networking framework and operating system.

"The core principles of AXOS -- fast innovation delivery, always on operation, and simple integration -- provide tangible benefits to service providers and their device-enabled subscribers through the rapid turn-up of services and an unmatched broadband experience," said Carl Russo, Calix president and CEO. "Calix was the first company willing and able to disrupt the traditional approach to access networks. Now, we're delivering on the vision we've pursued for over a decade: to lead a revolution that will forever change the economics, the boundaries and possibilities of access. With more than 100 customers embracing the AXOS platform, the movement is unleashed, and we expect it to accelerate as the industry begins to appreciate the success of these first movers."

AXOS is a vital strategic element of the Calix Software Defined Access vision or SDA, providing a transparent, ubiquitous subscriber experience for business and residential deployments across telcos, cable operators, and a variety of new communications service providers by eradicating the traditional constraints and limitations of the access network while changing the economics to deploy and operate high-demand services.

By abstracting the services layers from the underlying hardware, AXOS is able to run all software functions in the access network on any fiber, copper or wireless physical technology. Service providers can take advantage of maximum flexibility in network design and deployment models while maintaining consistent services, operations integration, and methods of procedure.

Learn more about the award-winning AXOS platform and its role in transforming the service provider business model in this video interviewconducted by Light Reading with Calix president and CEO Carl Russo.

I’m still working through remarkable presentations from the Broadband Forum events. Michael Weissman, Bernd Hesse and team did a remarkable job choosing the speakers.

Deutsche Telecom: 35b Supervectoring Delayed to 2019
Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. 35b should deliver 200+ meg downloads 500-600 meters, a crucial tool for DT, which is losing share to cable. Cable now covers about 70% of Germany and is expanding. DT now only offers 50-100 megabit DSL while cable is often 400 megabits, going to a gigabit. 

The problem is software; the hardware is shipping and supposedly will work. DT says 35b is not ready to turn on. Broadcom in 2015 said 35b was in "production" in the press release below. Alcatel in early 2016 said to expect complete systems very soon. "35g is very similar to 17a so there should be little delay."

Broadcom's problems are leading major telcos and vendors to have a plan B, using Sckipio DT itself is planning extensive deployments in 2019, mostly in apartment buildings.

Gigabit 100 Meters - Unless the Wires are Lousy
Speeds are fine, "Unless there's a line problem." I've been reporting for three years that ~10% of lines have problems. In the chart by Rami Verbin of Sckipio, he finds goes ~130 meters on good lines. Poor lines have about half the reach. 

His chart roughly matches the reports from Swisscom, Belgacom, and England for both & vectored DSL. The 10% with problems can cause the majority of the line-related complaints to support. The angry customers drive up cost.

Rami's solution to reach the gigabit is bonding, supported on the Sckipio chips. Verbin made some additional points:

  • 4 gigabits is possible by bonding two decent 2 gigabit lines.
  • Even in a service from remote cabinets, ~25% are close enough to get a full gigabit."
  • cDTA and iDTA are practical ways to deliver much higher upstream by switching some bandwidth from downstream to upstream only when needed.
  • 35B will probably be similar but Deutsche Telecom doesn't expect to deploy until 2019.

AT&T Wants Coax 2-5 Gigabit Very Soon.
AT&T faces intense competition from cable, talking about 10 gigabits in both directions. (Cable will only be 1 gig down, ~100 meg up, until ~2021.) AT&T wants something to brag about as well.

AT&T gained millions of lines of coax as part of the DirecTV deal. Alcatel and Huawei are leading the development of G.mgfast. That uses 424 MHz, full duplex, to achieve ~2.5 gigabits in both directions. The reach on telco twisted pair is only about 30 meters. On coax, those speeds can probably extend far enough to service most apartment buildings. Using 848 MHz, speeds can reach 5 gigabits. The ITU standards group has been aiming for 2019-2020 for G.mgfast, too slow for AT&T's marketers. David Titus wants a high-speed standard for coax "early in 2018." He believes that is "doable."
