ABI forecasts NFV market to reach $38bn by 2022

According to ABI Research's latest Network Functions Virtualization Tracker and Forecasts report, after a slower start than initially anticipated, the network function virtualisation (NFV) market is set to experience moderate growth based on continuing NFV investments by major telcos.

ABI Research forecasts that North America will be the largest market, accumulating $13 billion in NFV-related investments during 2022, while Europe will see the highest growth rate with an estimated 53% CAGR between 2017 and 2022. The research firm notes that early adopters claim benefits offered by NFV-enabled systems including reductions in network capex and opex, service agility and faster deployment of new network elements.

ABI forecasts that overall NFV market revenue will reach $38 billion in 2022, although hardware expenditure, including servers, storage devices and switches, is expected to decline over time, while software and services segment spending is forecast to experience growth rates of 55% and 50%, respectively.

ABI notes that although the NFV market is evolving and technical expertise is starting to mature, the standardisation and multi-vendor involvement challenges will remain over the next two years. It adds that software and services vendors will have the opportunity to identify NFV use-cases for enterprise verticals and leverage these to deliver end-to-end integrated systems.

In terms of suppliers, ABI believes that the established vendors, including Ericsson, Huawei and Nokia, plus specialists such as Amdocs and Netcracker, will see early success, with systems integration becoming ever more important. It also notes that vendors are investing in open source software, which may increase business opportunities initially but could create difficulties in the future, particularly if telco interest in specific open source projects wanes.

ABI notes that currently, NFV is primarily seen as a means of reducing costs, but that new revenue opportunities will require a wider transformation which is likely to be driven by 5G after 2020.

Commenting on the report, Neha Pachade, senior analyst at ABI Research, said:

-           "In 2015 and 2016 the market experienced some early successes, but mostly reconsiderations and failures with NFV… early adopters conducted proof of concept testing and NFV-integrated system demonstrations to understand the impact of NFV in the technical, operational and cultural domains".


-           "Forecasts indicate that NFV will become a sizeable opportunity for vendors, although it is not yet clear whether it will cannibalise existing hardware-based product lines or create new market use cases".


Centec and DASAN Form Partnership

Video: Data Center Boom in Ireland


Will the data center boom accelerate in Ireland?

Ireland is already home to the largest concentration of major cloud providers in Europe. In recent months, we have seen Irish data center expansions from AWS, Google, Facebook, Equinix and Microsoft.  New next-gen transatlantic cables have landed on the Emerald isle.

With Brexit uncertaintly in the air, will even more data center operators move to Ireland?  In this video, Paraic Hayes, Vice President of IDA Ireland, says the government is extremely active to support the expansion of this activity with the goal of making Ireland the data capital of Europe.



Facebook dreams of better network connectivity platforms – Part 2

Preamble

Facebook has a stated goal of reducing the cost of network connectivity by an order of magnitude. To achieve this its labs are playing with millimetre wave wireless, free-space optics and drones in the stratosphere.

Project Aquila takes flight

At this year's F8 conference, Facebook gave an update on the Aquila drone aircraft, which is being assembled in California's Mojave Desert. The Aquila project is cool - pretty much everything about this initiative, from its name to its sleek design, has an aura about it that says 'this is cool', who wouldn't want to be developing a solar-powered drone with the wingspan of a Boeing 737. Using millimetre wave technology onboard Aquila, Facebook has achieved data transmission speeds of up to 36 Gbit/s over a 13 km distance; and using free-space optical links from the aircraft has achieved speeds of 80 Gbit/s over 13 km.

Several media sources reported a technical set-back last year (rumours of a cracked frame) but those are in the past or perhaps not relevant any more. At F8, Facebook said Aquila has progressed and is now ready for field testing. However, here again, one element that seems to be missing is the business case. Just where is this aircraft going to fly and who will pay for it?

As described by Facebook, Aquila will serve regions of the planet with poor or no Internet access. Apparently, this would not include the oceans and seas, nor the polar regions, where such an aircraft might have to hover for months or years before serving even one customer. Satellites already cover much of our planet’s surface and for extremely remote locations this is likely to remain the only option for Internet access. New generations of satellites, include medium earth orbit (MEO) constellations, are coming with improved latency and throughput. So Facebook's Aquila must aim to be better than the satellites.

The aircraft is designed to soar and circle at altitudes up 90,000 feet during the day, slowly descending to 60,000 by the end of the night. The backhaul presumably will be a free-space laser to a ground station below. At such a height, Aquila would be above the weather and above the jet stream. During the day, with an unobscured view of the sun, it would recharge the batteries needed to keep flying at night.

Apart from satellites, the alternative architecture for serving such regions would be conventional base stations mounted on tall masts and connected via fibre, microwave or satellite links. Many vendors are already offering solar-powered versions of these base stations, and there are plenty of case studies of how they have been used successfully in part of Africa, and the advantages over a high-flying drone are obvious: mature technology, fixed towers and known costs, no possibility of dangerous or embarrassing crashes.

One could imagine that the Facebook approach might bring new Internet access possibilities to areas such as the Sahara, the Atacama, over islands in the Indonesian archipelago. But is not clear if Aquila’s onboard radios would be powerful enough to penetrate dense forests, such as in the Amazon or Congo. So, if the best deployment scenario is a desert or island with some humans but insufficient Internet access, why is satellite service not a viable option? The likely answer again is economics. Perhaps the populations living in these regions simply have not had the money to purchase enough smartphones or laptops to make it worthwhile for a carrier to bring service.

A further consideration worth noting is that it may be difficult for an American company to secure permission to have a fleet of drone aircraft circling permanently over a sovereign nation. Intuitively, many people would not feel comfortable with a U.S. drone circling overhead, even if it were delivering faster social media.

Designing a communications platform for emergency deployments

Facebook's connectivity lab is also interested in disaster preparedness. At the F8 keynote, it unveiled Tether-tenna, a helicopter-drone that carries a base station and is connected via fibre and a cable with high-voltage power to a mooring station. The system is designed for rapid deployment after a natural disaster and could provide mobile communications over a wide area. But is it a complex technology that provides minimal benefits (certainly not an order of magnitude) over existing solutions?

The closest equivalent in the real world is the cellular-on-wheels (COWs) segment, which is now commonly used by most mobile operators for extending or amplifying their coverage during special events such as outdoor concerts and football matches. A typical COW is really just a base station mounted on a truck or trailer. After being hauled to the desired location, the units can be put into operation in a matter of minutes, using on-board batteries, diesel generators or attachment to the electrical grid. The units often have telescoping masts that extend 4-5 metres in height.

In comparison to a COW, Facebook's Tether-tenna heli-drone will have a height advantage, perhaps 100 metres over the competitors, enabling it to extend coverage over a greater range. However, the downsides are quite apparent too. Base station weight restrictions on the heli-drone, which also must carry the weight of the tether, will be more limiting than on a mast, and this means that the Tether-tenna will not provide the density of coverage possible via a COW, thereby limiting its potential use cases.

In addition, a crashing heli-drone could do a lot of damage to people or property on the ground, and wind would be a major factor, as would lightning strikes. There is also the possibility of collisions with other drones, airplanes or birds. Therefore ensuring safety might require a human operator to be present when the drone is flying, and insurance costs inevitably would be higher than any of the many varieties of COWs that are already in service.

AT&T has a more elegant name for this gear, preferring to call them Cells on Light Trucks (COLTs). During the recent Coachella 2017 music festival in California, AT&T deployed four COLTs equipped with high-capacity drum set antennae, which offer 30x the capacity of a traditional, single-beam antenna. AT&T reported that the COLTs were instrumental in handling the 40 Tbit/s of data that traversed its network during the multi-day event - the equivalent of 113 million selfies. Data traffic from Coachella was up 37% over last year, according to AT&T. Would a heli-drone make sense for a week-long event such as this?  Probably not, but it's still a cool concept.

All of this raises the question: is a potential business case even considered before a development project gets funded at Facebook?

In conclusion, Facebook is a young company with a big ambition to connect the unconnected. Company execs talk about a ten-year plan to advance its technologies, so they have the time and money to play with multiple approaches that could make a difference. A business case for these three projects may not be apparent now but they could evolve into something serendipitously.

Calix and Radisys Partner on Residential CORD

Radisys and Calix announced the delivery of an end-to-end cloud edge solution based on commercially available systems and software that is compliant with the Residential Central Office Re-architected as a Datacenter (R-CORD) architecture, designed to enable SDN, NFV and the cloud model in the access network.

This video, hosted by Joseph Sulistyo, Senior Director of Open Networking Solutions at Radisys, provides a broad overview...


Coriant trials disaggregated 100/150/200G with Telefónica Germany

Coriant completed a network trial with Telefónica Germany that featured disaggregated 100, 150 and 200 Gbit/s transmission over live fibre links in the existing 10 Gbit/s DWDM dispersion compensated network.

The recently completed trial with Telefonica Germany involved the Coriant Groove G30 network disaggregation platform and demonstrated the ability to cost-efficiently increase the performance of deployed optical infrastructure using advanced disaggregated optical transmission and open networking capabilities.

The alien wavelength trial was implemented over three separate live links in Telefónica's existing 10 Gbit/s DWDM transmission network spanning distances of 1,070 km, 630 km and 290 km, with connectivity to key network sites including Düsseldorf and Frankfurt.

Supporting interoperability with Telefónica's existing 10 Gbit/s optical line system, the Coriant Groove solution achieved disaggregated 100 Gbit/s transport across all three links, 150 Gbit/s over the 630 km and 290 km links, and 200 Gbit/s capacity over the 290 km connection.

Coriant stated that following the successful trial, in mid-2017 it plans to work with Telefónica Germany to conduct further alien wavelength testing on the operator's 100 Gbit/s national backbone network in Germany utilising the disaggregated Coriant Groove G30 muxponder solution.




  • In 2015, Telefónica Germany deployed the Coriant 8600 Smart Router Series and 8000 Intelligent Network Manager (INM) to upgrade its mobile backhaul network and support the integration of the O2 and E-Plus network infrastructures.

ADTRAN demos ITU G.fast 212 MHz and coordinated DTA

ADTRAN has announced that it is conducting what is believed to be the first public demonstration of the ITU-T's two most recent G.fast advances, specifically 212 MHz and coordinated dynamic time allocation (cDTA), at the G.fast Summit 2017 in Paris.

ADTRAN noted that the latest G.fast advances are intended to enable the delivery of symmetric gigabit services over a single copper pair, mitigating the need to bond multiple pairs of copper wire and allowing service providers to extend business-class gigabit services over the existing wiring.

At the G.fast Summit ADTRAN is demonstrating its new 212 MHz G.fast standard, which doubles the usable spectrum and enables the delivery of gigabit rates over a single copper pair and offering an alternative to the use of fibre. ADTRAN has also extended its reverse power feature set to the new solution, simplifying sourcing of local power.

Together, the new capabilities are claimed to enable service providers to accelerate gigabit and ultra-fast broadband service deployments by an estimated 12 to 18 months and reduce costs by up to one third per subscriber. The technology is also intended to offer a competitive alternative to DOCSIS 3.1.

ADTRAN noted that it first demonstrated DTA over coax technology at G.fast Summit 2016, with cDTA the second generation technology. The cDTA function can improve G.fast upstream performance by a factor of four- to five-fold by dynamically balancing upstream and downstream performance to match residential traffic patterns in real-time. Unlike DTA, cDTA extends the applications of the feature to existing phone wiring in residential and commercial premises.

Designed to form a key part of the ADTRAN MOSAIC Open Software Defined Access platform, operators adopting the new solutions can ensure that the G.fast access elements in their network are prepared for the transition to SDN in the future.

Facebook dreams of better network connectivity platforms – Part 1


Facebook's decision to launch the Open Compute Project (OCP) six years ago was a good one. At the time, Facebook was in the process of opening its first data centre, having previously leased space in various third party colocation facilities. As it constructed this first facility in Prineville, Oregon the company realised that it was going to have to build faster, cheaper and smarter if this strategy were to succeed, and that to keep up with its phenomenal growth it would have to open massive data centres in multiple locations.

In 2016, Facebook kicked off the Telecom Infra Project (TIP) with a mission to take the principles of the Open Compute Project (OCP) model and apply them to software systems and components involved in access, backhaul and core networks. The first TIP design ideas look solid and have quickly gained industry support. Among these is Voyager, a 'white box' transponder and routing platform based on Open Packet DWDM. This open line system will include Yang software data models of each component in the system and an open northbound software interface (such as NETCONF or Thrift) to the control plane software, essentially allowing multiple applications to run on top of the open software layer. The DWDM transponder hardware includes DSP ASICs and complex optoelectronic components, and thus accounts for much of the cost of the system.

The hardware design leverages technologies implemented in Wedge 100, Facebook's top-of-rack switch, including the same Broadcom Tomahawk switching ASIC. It also uses the DSP ASIC and optics module (AC400) from Acacia Communications for the DWDM line side with their open development environment. Several carriers and data centre operators have already begun testing Voyager platforms from multiple vendors.

In November 2016, Facebook outline its next TIP plans including Open Packet DWDM for metro and long-haul optical transport networks. This idea is intended to enable a clean separation of software and hardware based on open specifications. Again, there is early support for a platform with real world possibilities, either within Facebook's global infrastructure or as an open source specification that is ultimately adopted by others.

What's cooking at Facebook's network connectivity labs

At its recent F8 Developer’s conference in San Jose, Facebook highlighted several other telecom-related R&D projects out of its network connectivity lab that seem to be more whimsical fancy than down-to-earth practicality. In the big picture, these applied research projects could be game-changers in the race to the billions of people worldwide currently without Internet access, or potential Facebook users of the future. Facebook said its goal here is to bring down the cost of connectivity by an 'order of magnitude', a pretty high bar considering the pace of improvement already seen in mobile networking technologies.

This article will focus on three projects mentioned at this year's F8 keynote, namely: Terragraph, a 60 GHz multi-node wireless system for dense urban areas that uses radios based on the WiGig standard; Aquila, a solar-powered drone for Internet delivery from the stratosphere; and Tether-tenna, a sort of helicopter drone with a base station. It is not clear if these three projects will eventually become part of the TIP of even if they will progress beyond lab trials.

Terragraph

Terragraph is Facebook's multi-node wireless system for delivering high-speed Internet connectivity to dense urban areas and capable of delivering gigabit speed to mobile handsets. The scheme, first announced at last year's F8 conference, calls for IPv6-only Terragraph nodes to be placed at 200-metre intervals. Terragraph will incorporate commercial off-the-shelf components and aim for high-volume, low-cost production. Facebook noted that up to 7 GHz of bandwidth is available in the unlicensed 60 GHz band in many countries, while U.S. regulators are considering expanding this to a total of 14 GHz. Terragraph will also leverage an SDN-like cloud compute controller and a new modular routing protocol that Facebook has optimised for fast route convergence and failure detection. The architecture also tweaks the MAC layer to solve shortcomings of TCP/IP over a wireless link. The company says the TDMA-TDD MAC layers delivers up to 6x improvement in network efficiency while being more predictable than the existing WiFi/WiGig standard.

At the 2017 F8 conference, Facebook talked about how Terragraph is being tested in downtown San Jose, California, a convenient location given that is right next door for Facebook. Weather will not be a significant factor since San Jose does not experience the rolling summer fog of nearby San Francisco, nor does it suffer torrential tropical downpours, whiteout blizzard conditions, scorching summer heat, or Beijing-style air pollution that could obscure line-of-sight.

While the trial location might be ideal, one should also consider in which cities would Terragraph be practical. First, there are plenty of WiFi hotspots throughout San Jose and smartphone penetration is pretty much universal and nearly everyone has 4G service. Heavy data users have the option on unlimited plans from the major carriers. So maybe San Jose only serves as the technical trial and the business case is more applicable to Mexico City or Manaus, Lagos, Nairobi, or other such dense urban areas.

At the F8 conference, Facebook showed an AI system being used to optimise small cell placement from a 3D map of the city centre. The 3D map included data for the heights of buildings, trees and other obstacles. The company said this AI system alone could be a game changer simply by eliminating the many hours of human engineering that would be needed to scope out good locations for small cells. However, the real world is more complicated. Just because the software identifies a particular light pole as an ideal femtocell placement does not mean that the city will approve it. There are also factors such as neighbour objections, pole ownership, electrical connections, etc., that will stop the process from being fully automated. If this Terragraph system is aimed at second or third tier cities in developing countries, there is also the issue of chaotic development all around. In the shanty towns surrounding these big conurbations, legal niceties such as property boundaries and rights-of-way can be quite murky. Terragraph could be quite useful in bringing low-cost Internet into these areas, but it probably does not need fancy AI to optimise each small cell placement.

Generally speaking, 3G and now 4G services have arrived in most cities worldwide. The presumption is that Facebook is not seeking to become its own mobile carrier in developing countries but that it would partner with existing operators to augment their networks. Meanwhile one suspects that the reason carriers have been slow to upgrade capacity is certain neighbourhoods or cities is more economic than technical. It is probably not a lack of spectrum that is holding them back, nor a lack of viable femtocell products or microwave backlinks, but simply a lack of financial capital or a weak return on investment, or red tape. One reason for this that is often cited is that over-the-top services, such as Facebook, suck all the value out of the network, leaving the mobile operator with very thin margins and little customer stickiness.


Part 2 of this article we will look at Facebook's Aquila and Tether-tenna concepts.

Verizon expands universal CPE portfolio with whitebox, OpenStack

Verizon announced it has expanded its Virtual Network Services offering with the addition of x86-based whitebox options leveraging OpenStack to its universal customer premises equipment (uCPE) portfolio.

Verizon's uCPE offering means that enterprises do not need to invest in separate, dedicated hardware appliances to deliver key virtual network functions (VNFs) such as software-defined WAN (SD-WAN), security, routing, WAN optimisation, or any network function that can be virtualised.

Verizon is seeking to simplify the transition to software-defined, application-centric network deployments for organisations of any size by expanding its Virtual Network Services uCPE options from vendor-specific platforms to an open hardware, open source whitebox architecture.

Verizon's uCPE portfolio targets applications ranging from solutions suitable for small retail sites up to large data centre deployments and leverages commercial-off-the-shelf (COTS) hardware and a globally distributed open source architecture. This allows enterprises to rapidly deploy services globally using Verizon's application library.

The uCPE solution features service chaining and enterprise orchestration functionality that enables automated onboarding and provisioning, with future orchestration releases to offer service assurance capabilities for fault and performance monitoring, closed-loop healing and a VNF factory. The enhanced life-cycle orchestration capabilities are designed to enable enterprises to implement near real-time SDN technologies.


Verizon noted that the combination of COTS hardware and a distributed deployment of OpenStack allows customers to decouple hardware from software and removes the need for proprietary hardware. This capability can help customers to reduce costs and simplify the physical network architecture, as well as allowing them to choose the most suitable hardware and applications for their individual requirements.
