EU allows exceptions to Open Internet law for COVID-19 emergency

In anticipation of network capacity issues, the European Commission and the Body of European Regulators for Electronic Communications (BEREC) announced several initiatives to provide some flexibility to network operators in how they manage congestion.

Specifically, the directive provides certain temporary exceptions to the EU's Open Internet Access provisions of Regulation (2015/2120), which prohibits operators from blocking, slowing down or prioritising traffic.

"Pursuant to the Regulation, operators are authorised to apply exceptional traffic management measures, inter alia, to prevent impending network congestion and to mitigate the effects
of exceptional or temporary network congestion, always under the condition that equivalent categories of traffic are treated equally. This could become relevant, following the confinement
measures taken to address the Covid-19 crisis. Operators can avail themselves of this exception, if such traffic management measures are necessary to solve or to prevent the congestion and they can only be maintained for as long as necessary."

European operators cite spike in network traffic

Leading European operators, including Movistar, Orange, Vodafone, Grupo Masmovil and Grupo Euskaltel, are asking the public to adopt a rational and responsible approach to the use of telecommunication networks due to the massive spike in traffic during the COVID-19 crisis.

Telefónica said traffic through IP networks has experienced increases of nearly 40% while mobile use has increased by about 50% in voice and 25% in data. Likewise, traffic from instant messaging tools such as Whatsapp has increased fivefold in recent days.

The operators issued the following public requests:

  • Only download the documents or files that you really need, and if they can wait, do it at night or in the "off-peak hours" with less traffic (between two and four in the afternoon and between eight in the evening and eight in the morning).
  • Whenever possible, do not send heavy files -videos, presentations...-. Send links or routes to where they are stored. And, if it is essential to send them, compress them first or give them a format that weighs less (from ppt to pdf, for example). 
  • Use collaboration tools like Teams or Slack, and if you can, don't always do it with video.
  • Avoid massive e-mails.
  • Use your landline phone instead of your mobile phone to make calls when possible.
  • And, above all, optimise the traffic for what you really need: email, remote work, conferences, school and education applications, access to information... reserve leisure tools, video games, streaming, live video playback for the off-peak hours.

Dell'Oro: Anemic growth in data center switch market during 4Q19

The worldwide Data Center Switch market revenue grew only one percent year-over-year (Y/Y) in 4Q 2019, according to a recent report by Dell'Oro Group. This is the slowest growth recorded in six years. Revenue from North America and Europe was down but, surprisingly, China grew at a strong double-digit Y/Y rate during the quarter.

“In line with our expectations, the Top 4 U.S. Cloud Service Providers (SPs) posted mixed performance. Google and Amazon’s strong growth was partially offset by weakness from Facebook and Microsoft,” said Sameh Boujelbene, Senior Director at Dell’Oro Group. “Additionally, ongoing macroeconomic uncertainties in North America and Europe continued to weigh on network spending from Tier 2/3 Cloud SPs and large enterprises. However, what’s intriguing this quarter is the growth witnessed in China despite macroeconomic headwinds in the region. We believe part of this growth could reflect inventory buildup as well as some government projects to stimulate the economy,” added Boujelbene.

Additional highlights from the Ethernet Switch – Data Center Quarterly Report:

  • Market softness is expected to persist through 1H 2020.
  • Macroeconomic headwinds are expected to deteriorate due to the potential impact from Coronavirus (COVID-19) on demand as well as supply.
  • Arista, Cisco, Juniper, and Dell initiated early 400 Gbps shipments.

IDC: The impact of COVID-19 on the semiconductor sector

International Data Corporation (IDC) has published a report that analyzes the impact of the COVID-19 pandemic on the global semiconductor market and presents several possible outcomes.

"The emergence of COVID-19 has brought with it travel bans and quarantines; massive slowing of the supply chain; uncertainty in the stock market; falling business confidence, and growing panic among the population," said Mario Morales, program vice president, Semiconductors and Enabling Technologies at IDC. "Despite the growing uncertainty and panic, technology suppliers must continue to focus on their long-term investments, maintain engagement with partners and prospects, and look to specific markets for stability. Emerging technologies like 5G, the Internet of Things, high-performance computing, and intelligent edge will be fundamental to an overall recovery by the technology sector."

The report provides a framework to evaluate the market impact through four scenarios that assess the range of possible outcomes. Each scenario is based on varying assumptions and severity of the impact to business for technology suppliers. For each scenario, a range of critical factors are assessed with a resulting updated forecast, presented with leading indicators to help clients navigate this emergency.

Some highlights:

  • There is nearly an 80% chance for significant contraction in worldwide semiconductor revenues in 2020, instead of a previously expected minor overall growth of 2%.
  • There is still a one-in-five chance that a fast, strong bounce back from COVID-19 in 2020 is possible.
  • On a global level, the COVID-19 crisis is just beginning, with too many variables to immediately craft a single forecast in response.
  • The impact to technology supply chains in China are significant, but the timing of the recovery is uncertain.

Verizon cites week-over-week rise in traffic

Verizon reported the following week-over-week comparisons of peak hour usage traffic over its residential fiber and wireless consumer networks:

  • Gaming, up 75%
  • VPN, up 34%
  • Web traffic up close to 20%
  • Video, up more than 12%
  • Social media usage: 0%, flat

Verizon said usage is expected to fluctuate over time, especially as more people telecommute and more students are at home.

“As we see more and more individuals work from home and students engage in online learning, it is a natural byproduct that we would see an increase in web traffic and access to VPN.  And as more entertainment options are cancelled in communities across the US, an increase in video traffic and online gaming is not surprising,” said Kyle Malady, Chief Technology Officer for Verizon.  “We expect these peak hour percentages to fluctuate, so our engineers are continuing to closely monitor network usage patterns 24x7 and stand ready to adjust resources as changing demands arise.”

“We’re in an unprecedented situation,” said Malady. “We continually evaluate peak data usage times and build our networks to stay ahead of that demand.  “While it is not clear yet how having millions of additional people working from home will impact usage patterns, we remain ready to address changes in demand, if needed.”

Infinera carries 800G wavelength at 96 Gbaud over 950km

Infinera completed a live network trial of 800G single-wavelength transmission at 96 Gbaud over 950 kilometers (km) across a long-haul link in a major North American network operator’s production network.

The production network trial, which was conducted over a third-party optical line system carrying live multi-vendor traffic, leveraged Infinera’s Groove (GX) Series, equipped with its sixth-generation dual-800G Infinite Capacity Engine (ICE6) technology.  The trial demonstrated Infinera’s vertically integrated ICE6 optical engine, which features second-generation Nyquist subcarriers, 64QAM with per-subcarrier long-codeword probabilistic constellation shaping, and per-subcarrier dynamic bandwidth allocation. The operator's network used G.652 fiber.

ICE6 combines Infinera’s sixth-generation photonic integrated circuit with its in-house-developed 7-nanometer dual-channel 800G per-wave FlexCoherent digital signal processor.

Corning’s state-of-the-art TXF fiber is an ITU-T G.654.E compliant, ultra-low-loss, silica-core fiber with large effective area.

The companies said the success of the 800G trial highlighted the advanced features of Infinera’s vertically integrated ICE6 technology, including Nyquist subcarriers, per-subcarrier long-codeword PCS, and per-subcarrier dynamic bandwidth allocation, along with superior fiber designed to help meet growing bandwidth demands for network operators from metro to subsea network applications.

NeoPhotonics intros 64 GBaud L-band coherent optical components

NeoPhotonics introduced an L-Band suite of coherent optical components, including its 64 GBaud L-Band High Bandwidth Coherent Driver Modulator (HB-CDM), 64 GBaud L-Band Intradyne Coherent Receiver (ICR) and ultra-narrow linewidth L-Band tunable laser Micro-ITLA. NeoPhotonics already supplies standard C-Band coherent components.

NeoPhotonics notes that the L-Band uses wavelengths centered around 1590 nm and is primarily used to complement the C-Band (1550 nm) to increase data capacity, especially in long-haul networks. By adding channels in the L-Band, operators can double the capacity of an optical fiber. NeoPhotonics 64 Gbaud coherent components and tunable lasers enable single channel 600G data transmission over short haul data center interconnect (DCI) links using 64 QAM. These components also support 400G over metro distances of 400-600 km using 64 GBaud and 16 QAM or 200G over long-haul distances of greater than 1000 km using 64 GBaud and QPSK.

The NeoPhotonics L-Band External Cavity (ECL) micro-ITLA incorporates the same laser architecture as its C-Band laser for a pure optical signal with an ultra-narrow linewidth and very low phase noise. In coherent systems, any error in the phase of the signal and reference lasers, due to the laser’s linewidth, can cause data errors, thereby making narrow linewidth critical in systems using higher order modulation.

The NeoPhotonics 64 Gbaud L-Band HB-CDM co-packages an Indium Phosphide based Mach-Zehnder (MZ) quadrature modulator chip with a linear, quad-channel, differential 64 GBaud driver. Both the C-Band and L-Band versions of the HB-CDM are designed to be compliant to the Optical Internetworking Forum (OIF) Implementation Agreement OIF-HB-CDM-01.0 “High Bandwidth Coherent Driver Modulator”.

NeoPhotonics 64 Gbaud L-Band Micro-ICR incorporates an integrated comixer chip and four balanced photodiodes with four differential linear amplifiers to provide four output channels at 64 GBaud. The form factor of the High Bandwidth Coherent Receiver is designed to be compliant with the OIF Implementation Agreement for Micro Integrated Intradyne Coherent Receivers; IA # OIF-DPC-MRX-02.0.

For applications that require more capacity than provided by the standard C-Band, but do not require the full L-Band, each of these components is available in a “C++” version, which supports tuning across the full “Super C-band” covering 6.0 THz of spectrum or up to 50 percent more than standard systems. These C++ components can support 80 channels at 75 GHz channel spacing, which effectively increases the capacity of an optical fiber by as much as 50 percent over standard C-Band only systems at comparable distances.

"We are pleased to add L-Band versions to our existing suite of coherent components, thus providing customers with a complete solution to their fiber capacity requirements, whether C-Band, C++ Band or L-Band," said Tim Jenks, Chairman and CEO of NeoPhotonics. "Our ultra-pure tunable laser design and our high performance coherent modulator and receiver designs are very flexible and excel in different spectral regimes to provide the highest speed over distance performance," concluded Mr. Jenks.
