Nokia debuts AirScale All-in-Cloud base station

Nokia rolled out a series of enhancements to its AirScale portfolio including a Dynamic Spectrum Sharing (DSS) software upgrade for existing Nokia AirScale base stations and introduction of a Nokia AirScale All-in-Cloud base station.

Nokia’s DSS solution, delivered as a software upgrade to existing Nokia AirScale base stations, enables dynamic sharing between 2G, 3G, 4G and 5G technologies. The 4G–5G DSS feature, which has been the subject of interest from operators in leading 5G markets, automatically co-ordinates the spectrum usage between 4G and 5G, helping them reuse existing 4G radio networks and speed up 5G rollouts. Typically, 5G is launched in higher mmWave or cmWave spectrum, while existing 4G is deployed in the lower spectrum range. By reusing the lower-frequency 4G spectrum, 5G coverage can be achieved faster and at a lower cost. Initial deliveries of Nokia’s DSS solution are planned to start in April 2020, with volume shipments expected by July, in line with the availability of DSS-capable mobile devices.

The new Nokia AirScale All-in-Cloud base station virtualizes real-time baseband and puts the baseband processing power at the edge of the network to meet extremely low-latency requirements, boosting the efficiency of the network. Nokia Bell Labs is developing an AirScale Cloud-native RAN.

The rollout also includes compact dual and triple-band remote radio heads to support cell site deployment requirements, as well as several new high-performance massive MIMO adaptive antennas to deliver 5G coverage and high capacity.

Tommi Uitto, President of Mobile Networks at Nokia, commented: “All of these upgrades are designed to support mobile operators in their efforts to deliver compelling 5G experiences to their customers faster and at a lower cost. They will also support with increased demand for capacity, which is critical in the current environment. Our latest portfolio innovations will help operators to take advantage of the 5G world by delivering new use cases and business models and add new revenue streams.”

Google gains partial clearance for Pacific Light subsea cable

Google was granted clearance by the FCC to operate the segment of the Pacific Light Cable Network System connecting the United States to Taiwan for the next six months, pending a final disposition of the license application. The temporary authorization does not authorize any commercial traffic on the subsea cable segments to/from the Philippines or Hong Kong.

The U.S. Department of Justice, along with the Departments of Homeland Security and Defense, advised the FCC that those agencies do not oppose Google's request carry traffic over the cable between the U.S. and Taiwan.

In its application for Special Temporary Authority, Google emphasized “an immediate need to meet internal demand for capacity between the U.S. and Taiwan” and that without the sought temporary authority Google would likely have to seek alternative capacity at “significantly higher prices.”

Under the terms of the Provisional National Security Agreement, Google has agreed to a range of operational requirements, notice obligations, access and security guarantees, as well as auditing and reporting duties, among others. The Provisional National Security Agreement also includes a commitment by Google to “pursue diversification of interconnection points in Asia,” as well as to establish network facilities that deliver traffic “as close as practicable” to its ultimate destination.  This term reflects the views of the Executive Branch that a direct cable connection between the United States and Hong Kong would pose an unacceptable risk to the national security and law enforcement interests of the United States.

Google and Facebook Team Up for Pacific Light Cable Network

Facebook and Google are teaming up to build the highest capacity, trans-Pacific cable system to date.

The Pacific Light Cable Network (PLCN), which will stretch 12,800 km between Los Angeles and Hong Kong, will have an estimated cable capacity of 120 Tbps.  The cable is expected to enter service in the summer of 2018. The project is organized by Pacific Light Data Communication Co. Ltd., a new company based in Hong Kong.

TE SubCom has been appointed lead contractor. The cable will use TE SubCom’s C+L technology, a major step forward in available cable transmission capacity that effectively doubles the available bandwidth and capacity per fiber pair over a traditional C-band-only designed system.

Google noted that it has now taken an ownership stake in six submarine cables: PLCN, Unity, SJC, FASTER, MONET and Tannat.

US Department of Justice recommends banning China Telecom

The U.S. Department of Justice issued a recommendation to the FCC to revoke and terminate China Telecom (Americas) Corp.’s authorizations to provide international telecommunications services to and from the United States. 

The Department of Justice said its recommendation was based on:

  • the evolving national security environment since 2007 and increased knowledge of the PRC’s role in malicious cyber activity targeting the United States;
  • concerns that China Telecom is vulnerable to exploitation, influence, and control by the PRC government;
  • inaccurate statements by China Telecom to U.S. government authorities about where China Telecom stored its U.S. records, raising questions about who has access to those records;
  • inaccurate public representations by China Telecom concerning its cybersecurity practices, which raise questions about China Telecom’s compliance with federal and state cybersecurity and privacy laws; and
  • the nature of China Telecom’s U.S. operations, which provide opportunities for PRC state-actors to engage in malicious cyber activity enabling economic espionage and disruption and misrouting of U.S. communications. 

“Today, more than ever, the life of the nation and its people runs on our telecommunications networks,” said John C. Demers, Assistant Attorney General for National Security.  “The security of our government and professional communications, as well as of our most private data, depends on our use of trusted partners from nations that share our values and our aspirations for humanity.  Today’s action is but our next step in ensuring the integrity of America’s telecommunications systems.”

Fastly measures traffic spikes vs download performance

Fastly published traffic analysis that delves into regional trends for key U.S. states, as well as the countries of France, Italy, Japan, Spain, and the UK, that are some of the most impacted by the COVID-19 pandemic (as of the end of March 2020). The overall conclusion is that the Internet is holding up to the surging traffic volumes resulting from home quarantines.

“Overall, the internet is in good health,” said Fastly’s Chief Architect and Founder, Artur Bergman. “This is partly due to the regionality of these trends, but modern websites and applications are also better able to adapt to changing internet conditions. We are seeing the internet bring people together, whether for work, entertainment, or to get in touch with family and friends. And while there’s more traffic than in previous months, the internet is resilient.”

For analysis of regional traffic, Fastly used the following metrics, which were gathered from sampled TCP connection stats (tcp_info) at connection close time as part of Fastly’s fleet-wide performance monitoring infrastructure:

Traffic represents the average number of data bytes per day that were delivered to various geographies from all of our servers (acked_bytes field in tcp_info).
Download speed represents the delivery rate reported by TCP over all connections from a region, averaged over a day (delivery_rate field in tcp_info). While the reported values are averages, various percentiles for download speeds all show similar trends and ratios to the average.
For global analysis of verticals, Fastly measured average requests per second (RPS) recorded at all our servers. RPS is a count of requests received at our serves from end users every second.

Some highlights


  • One-month traffic trends: Over one month, from respective traffic baselines, all regions analyzed reported increases in traffic with decreases in download speed, with the exceptions of Japan and California.
  • Most notably, Italy saw a 109.3% increase in traffic, with a 35.4% decrease in download speed.
  • Japan observed a 31.5% increase in traffic, but, markedly differentiated from other analyzed countries experiencing the impacts of COVID-19’s pandemic in their communities, it saw a 9.7% increase in download speed. Japan’s internet infrastructure seems to have absorbed this increased traffic.
  • In the U.S., New York and New Jersey saw a 44.6% increase in traffic, but were able to weather it with a relatively modest 5.5% decrease in download speed.
  • California saw a 46.5% increase in traffic, with a 1.2% increase in download speed. Similar to Japan, California’s internet infrastructure appears to have absorbed this increased traffic.
  • School closures and regional stay-at-home orders: In France, Fastly observed a 45.4% increase in traffic shortly after its government announced school closures on March 12. This increase in traffic did not show a noticeable reduction in download speed, but on March 17, when schools closed and the national lockdown went into effect, download speed decreased by 20.6%. In Italy, traffic increased by 47% around February 19, after public information about lockdowns of various parts of Northern Italy began. After school closures go into effect on February 24, download speeds fall by about 9.2% between February 18 and February 24. In Japan, traffic jumps by 38% and speed decreases by 9.2% between February 25 and February 29, when school closure announcements began. School closures in Spain on March 12 mark the beginning of traffic increases of 26.2%, while there is no speed reduction.
  • User experience: Across European nations, major streaming and VOD providers announced they would reduce the default bitrates of their video streams around March 19 in order to prevent the internet from acute strain. When analyzing traffic and download speed in France, Italy, and Spain, the reductions do not seem to have led to significant improvements in internet quality, but they may have helped keep it from deteriorating further. Additionally, beyond Europe, people who have had lower speed internet connections before coronavirus-related developments may currently be suffering from greater degradation than those who had higher speed broadband connections. Someone with a high-quality, 100Mbps internet connection might not even notice a download speed reduction of 35% — a typical 1080P video stream requires just 6Mbps and fits well within the resulting 65Mbps download speed. However someone with a lower-quality connection to the internet, such as 10Mbps, is likely to notice this quality degradation: their typical 1080P movie might now automatically adjust down to 720P to fit within the resulting 6.5Mbps.
  • From these findings, we learn that speed decreases may be more aligned with population shifts toward more internet use from homes, rather than with a traffic increase alone. In general, most regions saw their download speeds stabilize once school closures and lockdowns were fully enacted, when most of the population became homebound. For most regions, this happened mid-to-late March.


Fastly also analyzed industry-specific internet activity by comparing average requests per second (RPS), week-over-week, between two sets of dates: January 6, 2020, and February 16, 2020; and February 16, 2020, to March 29, 2020. The first set of dates represent what Fastly considers to be activity attributed to organic growth, as mainstream attention on the pandemic had not yet picked up to its current pace. The second set of dates occur during a much more dynamic era of coronavirus-related developments, and was instructive in helping understand how human behavior may be shifting in response to COVID-19.

During those time frames for each of the below verticals, Fastly observed the following traffic patterns:

Streaming: From February 16 to March 29, streaming observed an increase in average RPS week-over-week by 29.6%. Similarly to gaming, this notable increase could reflect increased interest in streaming media content during lockdowns and social distancing.
News and digital publishing: Of all verticals analyzed, these brands saw the biggest increase in average RPS week-over-week from February 16 to March 29 at 70.16%. The elevated activity may correlate to increasing newsroom attention on COVID-19-related content as the first quarter of the year progressed.
Social Media: Social media platforms saw a 40.88% increase in average RPS week-over-week from February 16 to March 29. The greater increases in activity might represent a window into one way people are remaining connected with each other on various social media platforms.
GIFs/memes: Brands that help end users create and share things like memes and GIFs observed a 30.28% increase in average RPS week-over-week from February 16 to March 29. The unusually high increase in activity may indicate that, in reaction to disruptions to daily life, some consumers have turned to humor to get through difficult times and connect with others.
Gaming: From February 16 to March 29, gaming observed an increase in average RPS week-over-week by 28.54%. This could indicate that people are playing more virtual and online games as many communities look for ways to stay engaged while sheltering in place.
EdTech: From February 16 to March 29, edtech observed a noticeably sharp increase in average RPS week-over-week by 34.55%. This could indicate that edtech platforms are indeed growing their usage as more school-age children are educated from home.

VMware vRealize Network Insight 5.2 introduces flow-based application discovery across multiple VMware platforms using machine learning to better understand categorized applications by tier.
Making Security Intrinsic: VMware is taking internal security to the next level following the introductions of the industry-first Service-defined firewall and NSX Intelligence with the general availability of Intrusion Detection and Prevention (IDS/IPS) capabilities for the Service-defined Firewall. NSX Distributed IDS/IPS takes advantage of VMware’s unique intrinsic understanding of the services that make up applications to match IDS/IPS signatures to specific parts of the application. NSX Distributed IDS/IPS signatures are application specific and only applied to the appropriate servers, resulting in fewer false positives and significantly higher throughput. These capabilities enable efficiency and flexibility that cannot be matched by legacy and proprietary hardware-defined systems and are a major differentiator of the software-based scale-out approach of VMware NSX.
Full Stack Networking and Security for Modern Applications: Applications and microservices run on a wide variety of heterogenous endpoints such as VMs, containers, and bare metal servers, creating a challenge to consistently connect and secure them. NSX-T treats containers and VMs as first-class citizens, having supported Kubernetes platforms for more than two years. With the NSX-T 3.0 release, enterprises can extend its full stack container networking services including switching, routing, distributed firewall, micro-segmentation, and load balancing to the newly released VMware vSphere with Kubernetes and VMware Cloud Foundation 4 platforms, the VMware Tanzu portfolio, and non-VMware Kubernetes platforms.
End-to-End Visibility and Analytics: VMware vRealize Network Insight, available as on-premises software or SaaS, provides end-to-end network visibility and analytics to optimize network performance and troubleshoot the entire Virtual Cloud Network, including the virtual overlay and physical underlay, and spanning data centers, multi-cloud environments, and branch locations. New flow-based application discovery leverages unsupervised learning, statistical techniques, enriched network flows, and advanced application labelling algorithms to discover application and tier boundaries, providing insights into network communication density, applications patterns, and enhanced security recommendations. Other enhancements include, AWS Direct Connect support, VMware SD-WAN application and business policy statistics, enhanced Kubernetes visibility and support for VMware NSX-T 3.0.
Networking for Next-Generation Telco Clouds and 5G: With the Virtual Cloud Network, operators can build scalable networks to support 5G and edge strategies. VMware NSX plays a key role in accelerating network performance and efficient end-to-end network operations in the network core, serving as an SDN layer for virtual network functions. NSX-T 3.0 introduces capabilities such as L3 EVPN for VM mobility, multicast routing for scalable networking, and accelerated data plane performance. Additionally, VMware SD-WAN acts as an intelligent overlay in conjunction with 5G’s network sliced underlays to deliver more cost-effective, high-performance, application-aware services at the network edge.
Virtual Cloud Networking for Azure Edge Zones: VMware is working with Microsoft to offer SD-WAN solutions for Azure Edge Zones, which deliver Azure services and enable customers to seamlessly deploy and run Virtual Network Functions (VNFs) including VMware SD-WAN by VeloCloud. The VMware SD-WAN solution is fully integrated with the Azure portal and will enable Zero Touch Provisioning across Azure Edge Zones while shielding customers from operations and VNF life cycle management complexities.

Vantage Data Centers to acquire data center campus in Wales

Vantage Data Centers  signed a definitive agreement with InfraVia Capital Partners, along with the two founders of the business, to acquire Next Generation Data (NGD), which operates a data center campus located on 50-acres in the Cardiff Capital Region in South Wales, UK.

The existing NGD data center campus is a Tier III 180MW facility, including an existing 72MW capacity and 108MW of expansion capacity. It uses 100% renewable energy and is rich in fiber delivered by many Tier 1 service providers. Latency between Wales and London is less than 1.5 milliseconds. In addition, NGD Cloud Gateway provides multiple access services, including Express Route and Connect, and NGD recently became a new hosting facility for LINX Wales. The highly secure site meets the U.K. government’s highest standards, and is one of many reasons that multiple blue-chip, high growth companies currently house their IT infrastructure within NGD’s 750,000 square foot facility.

Upon closing, Wales will mark Vantage’s sixth strategic market in Europe following its entrance into five markets (Berlin, Frankfurt, Milan, Warsaw and Zurich) announced in February 2020, including the acquisition of Etix Everywhere.

“As the needs of our hyperscale, cloud and large enterprise customers continue to grow, Wales represents a highly attractive U.K. market offering both lower cost and greater scalability versus London,” said Sureel Choksi, president and CEO, Vantage Data Centers. “NGD customers benefit from very low network latency to London, low power costs and excellent fiber connectivity, coupled with the company’s massively scalable campus outside London’s highly constrained M25 area. We are thrilled to welcome Justin Jenkins and the entire NGD team to Vantage Europe.”

“The NGD team is excited to join Vantage Europe given our shared commitment to operational excellence, high quality facilities and sustainable building practices,” said Jenkins. “Vantage’s global footprint and broad customer relationships, combined with NGD’s growing hyperscale and enterprise U.K. customer base, position us ideally to accelerate the investment and growth of our U.K. business.”

The transaction will be funded with equity commitments from Digital Colony Partners and other investors in Vantage, as well as acquisition debt financing.

NXP Semiconductors trims Q1 outlook due to coronavirus

NXP Semiconductors trimmed its financial outlook for first quarter 2020, due to a worse than anticipated impact from the COVID-19 pandemic versus what the company had anticipated on March 2, 2020.

“Consistently during this challenging period, we have taken stringent actions to ensure the health and safety of all of our NXP team members and are extremely proud of their continued dedication,” said Richard Clemmer, NXP Chief Executive Officer. “Additionally, the impact to our first quarter results due to COVID-19 were more significant than we anticipated on March 2. While the supply chain disruption experienced post Lunar New Year in China appears to be subsiding, the end market demand trends in the rest of the world have started to significantly deteriorate. Throughout March, the demand headwinds accelerated in the automotive market where many global auto OEMs outside of China have shut production lines, and within the industrial and mobile markets where customer demand trends have resulted in the push-out of orders. We continue to be vigilant in the management of our distribution channel, aligning channel inventory to the sales out of the channel, and expect channel inventory to be consistent with prior periods, in the 2.4 months of supply range. Furthermore, we chose not to ship roughly $150 million of orders to our distribution partners in order to maintain our normal channel inventory. The current customer demand environment remains quite fluid and we will provide our best perspective for the second quarter during our earnings call on April 28.”

“While the demand environment is challenging, NXP continues to have a strong balance sheet and excellent liquidity. We expect our cash balance to be $1.1 billion as of the end of March, and in addition we have an untapped revolving credit facility of $1.5 billion, should we need it,” said Peter Kelly, NXP Chief Financial Officer.

Ethernet Technology Consortium focuses on 800G

The 25 Gigabit Ethernet Consortium, originally established to develop 25, 50 and 100 Gbps Ethernet specifications, has changed its name to the Ethernet Technology Consortium in order to reflect a new focus on higher-speed Ethernet technologies, the 800GBASE-R specification for 800 Gigabit Ethernet (GbE).

The 800 GbE specification introduces a new media access control (MAC) and Physical Coding Sublayer (PCS). It essentially re-purposes two sets of the existing 400GbE logic from the IEEE 802.3bs standard with a few modifications in order to distribute the data across eight 106 Gb/s physical lanes. As the PCS is reused, the standard RS(544, 514) forward error correction is retained, for simple compatibility with existing physical layer specifications.

The Ethernet Technology Consortium said its goal is to enhance the Ethernet specification to operate at new speeds by utilizing specifications that are developed or in development. This allows the organization to work alongside other industry groups and standards bodies to adapt Ethernet at a pace that aligns with the rapidly evolving needs of the industry. The ETC has more than 45 members with top-level promoter members that include Arista, Broadcom, Cisco, Dell, Google, Mellanox and Microsoft.

“Ethernet is evolving very quickly and as a group, we felt that having 25G in the name was too constraining for the scope of the consortium,” said Brad Booth, chair of the Ethernet Technology Consortium. “We wanted to open that up so that the industry could have an organization that could enhance Ethernet specifications for new and developing markets.”

“The intent with this work was to repurpose the standard 400GbE logic as much as possible to create an 800 GbE MAC and PCS specification with minimal overhead cost to users implementing multi-rate Ethernet ports,” said Rob Stone, technical working group chair of the Ethernet Technology Consortium. “The 800 GbE specification is an exciting first announcement under the consortium’s new name, reflecting the true capability of the organization. We are proud of the hard work of our member companies in completing this specification.”

Low latency spec for 50GbE tweaks forward error correction

The 25 Gigabit Ethernet Consortium has completed a low-latency forward error correction (FEC) specification for 50 Gbps, 100 Gbps and 200 Gbps Ethernet networks.

The new spec cuts FEC latency approximately in half by using a shortened codeword FEC variant – RS (272, 257+1, 7, 10) that replaces the IEEE 802.3cd and 802.3bs standard FEC.  The shortened codeword contains 272 x 10-bit symbols rather than the 544 x 10-bit symbols originally specified. Nothing else changes in the symbol distribution process from the output of the encoder to the FEC lanes in the new FEC, but that process is implemented more quickly due to the shortened codeword.

This will have a significant impact on overall physical layer latency, in particular for hyperscale datacenter networks comprised of a large number of nodes, with multiple hops between servers.

“Five years ago, only HPC developers cared about low latency, but today has latency sensitivity has come to many more mainstream applications,” said Rob Stone, technical working group chair of the 25G Ethernet Consortium. “With this new specification, the consortium is improving the single largest source of packet processing latency, which improves the performance that high-speed Ethernet brings to these applications.”

The specification is available at https://25gethernet.org/ll-fec-specification
