AT&T releases its Virtual Optical Line Termination Hardware Abstraction to ONF

AT&T is contributing its Virtual Optical Line Termination Hardware Abstraction (VOLTHA) code into the Open Networking Foundation (ONF).

VOLTA provides the framework behind AT&T's XGS-PON access network in the cloud. AT&T is currently performing proof-of-concept testing of VOLTHA in its labs and are planning to deploy XGS-PON field trials before the end of 2017.

AT&T described its decision to contribute its VOLTHA code as one more step in its commitment to move toward open source software and SDN/NFV frameworks.





AT&T to launch software-based 10G XGS-PON trial

AT&T announced it will conduct a 10 Gbit/s XGS-PON field trial in late 2017 as it progresses with plans to virtualise access functions within the last mile network.

The next-generation PON trial is designed to deliver multi-gigabit Internet speeds to consumer and business customers, and to enable all services, including 5G wireless infrastructure, to be converged onto a single network.

AT&T noted that XGS-PON is a fixed wavelength symmetrical 10 Gbit/s passive optic network technology that can coexist with the current GPON technology. The technology can provide 4x the downstream bandwidth of the existing system, and is as cost-effective to deploy as GPON. As part of its network virtualisation initiative, AT&T plans to place some XGS-PON in the cloud with software leveraging open hardware and software designs to speed development.
AT&T has worked with ON.Lab to develop and test ONOS (Open Network Operating System) and VOLTHA (Virtual Optical Line Terminator Hardware Abstraction) software. This technology allows the lower level details of the silicon to be hidden. AT&T stated that it has also submitted a number of open white box XGS OLT designs to the Open Compute Project (OCP) and is currently working with the project to gain approval for the solutions.

The company noted that interoperability is a key element of its Open Access strategy, and prompted the creation of an OpenOMCI specification, which provides an interoperable interface between the OLT and the home devices. This specification, which forms a key part of software-defined network (SDN) and network function virtualisation (NFV), has been distributed to standards and open source communities.



  • AT&T joined OCP in January 2016 to support its network transformation program. Earlier this year at the OCP Summit Edgecore Networks, a provider of open networking solutions and a subsidiary of Accton Technology, announced design contributions to OCP including a 25 Gigabit Ethernet top-of-rack switch and high-density 100 Gigabit Ethernet spine switch. The company also showcased new open hardware platforms.
  • At the summit, Edgecore displayed a disaggregated virtual OLT for PON deployment at up to 10 Gbit/ based on the AT&T Open XGS-PON 1 RU OLT specification that was contributed to the OCP Telco working group.
  • Edgecore's ASFvOLT16 disaggregated virtual OLT is based on the AT&T Open XGS-PON 1 RU OLT specification and features Broadcom StrataDNX switch and PON MAC SOC silicon, offering 16 ports of XGS-PON or NG-PON2, with 4 x QSFP28 ports and designed for next generation PON deployments and R-CORD telecom infrastructure.

IDC: Worldwide cloud IT infrastructure revenues up 25.8% in Q2

Vendor revenue from sales of infrastructure products (server, storage, and Ethernet switch) for cloud IT, including public and private cloud, grew 25.8% year over year in the second quarter of 2017 (2Q17), reaching $12.3 billion, according to IDC's updated Worldwide Quarterly Cloud IT Infrastructure Tracker service.

"The strength in public cloud growth continued at an accelerated pace through the first half of 2017," said Kuba Stolarski, research director for Computing Platforms at IDC. "We have already reported that most of this growth is being driven by Amazon. However, it is important to remember that many of the other hyperscalers – Google, Facebook, Microsoft, Apple, Alibaba, Tencent, and Baidu – are preparing for their own expansions and Skylake/Purley refreshes of their infrastructure.

Here are some highlights from IDC

  • Public cloud infrastructure revenue grew 34.1% year over year and now represents 33.5% of total worldwide IT infrastructure spending at $8.7 billion, up from a 27.0% share one year ago. 
  • Private Cloud revenue reached $3.7 billion for an annual increase of 9.9%. 
  • Total worldwide cloud IT infrastructure revenue has almost tripled in the last four years, while the traditional (non-cloud) IT infrastructure revenue continues to decline and is down 3.8% from a year ago, although it still represents 52.4% of the worldwide share of overall IT revenue at $13.6 billion for the quarter. 
  • Public Cloud now represents 70.2% of the total cloud IT infrastructure revenue. 
  • The market with the highest growth in the public cloud infrastructure space was Enterprise Storage Systems with revenue up 30.4% compared to the same quarter of the previous year, and making up over a third of the revenue in public cloud. 
  • Server and Ethernet Switch public cloud IT infrastructure revenues were up 24.6% and 26.8% respectively. 
  • Private cloud infrastructure spending continues to be driven by the server market, which has remained nearly 60% of the revenue in that space for the past 18 quarters.
