Perspective: Get your core (network) in shape during COVID-19

by Zoltan Varnai
Cloud Core Marketing Manager, Nokia

Some of you reading this blog may be doing so under lockdown, while working from home. Whether or not you are working is another matter, but regardless, you will be using data. In this current time, when so many people are staying indoors to prevent the spread of COVID-19 – replacing face-to-face meetings with virtual ones, going online to keep up-to-date with education, and to use streaming services for entertainment – is a common occurrence.

To stay sane and to normalize life as best as we can, it is more important than ever to remain connected with friends, family and colleagues. It is also important that we have access to strong and reliable connective networks, especially for essential workers who are bravely on the ‘front line’ of this health emergency. For instance, the heroic doctors, nurses and social workers that are actively fighting the virus need information promptly; they need to be ready for any situation. Information needs to be at their fingertips while they help a record influx of patients – I know because my sister is a doctor, and is often too busy to even take my phone calls. I proudly salute them all for the work they are doing every day.

This need for networks to meet growing demand is a challenge that operators are stepping up to. Around the world, they are ensuring that society can stay connected, companies can continue to work, and families can keep in touch. To address capacity and meet customer needs, many operators have suspended data caps, upgraded broadband speeds, changed call center opening hours, provided additional services for free and created new virtual services.

With so many changes in place designed to support the needs of our world today, there has been a drastic shift in network traffic profiles. As demonstrated by AT&T, demand is growing. The telecommunications giant reported up to 31% higher daily loading on its core network than the previous month, as well as a shift from urban to suburban and rural areas.

Focus on Maintaining Quality Services

As workload demands and needs grow and shift, maintaining uninterrupted, high-quality voice and data services is crucial. These specific factors have become the underpinning for most of the effort faced by network operators during this time.

Although there are several important components for an operator to address, it is crucial to focus on the mobile core network, which stands out in this instance as it quietly runs in the background to secure, authenticate and drive services delivered over networks. Meeting network demand means that the core network must be flexible and adaptable enough to accommodate where the demand is.
In a situation where the core is distributed across multiple regions, the connection between mobile core network elements must be adjusted to account for geographically-related demand. In modern day installations, artificial intelligence (AI) has become a great tool for operators looking to enable their optimization and monitoring needs, seamlessly. With AI-powered operations, it doesn’t matter whether operators have implemented traditional core networks or have already invested in flexible and scalable cloud-native core network architecture to adapt to the influx of network traffic.

Ensure a Strong Core

These unprecedented times have made operators adapt their core networks to accommodate an increase in network traffic much faster than most were expecting. Yet, as always, efficiency remains top-of-mind when determining new ways to use available core resources and support expansion. Once the core network is optimized and scaled, its health can be maintained through key initiatives set in place by network operators to measure network KPIs and provide insights into the network’s behavior to predict potential incidents.

Operators shouldn’t spend time worrying about the scalability, performance and reliability of their mobile core networks. Instead, they should focus on keeping their services functioning to the best of their ability to help their users and customers cope during this global crisis. It is more important than ever that connections – both personal and network-related – remain strong.

MIT advances quantum information sharing between processors

Researchers at MIT are developing an on-off system that leverages "giant atoms" to enable high-fidelity operations and interconnection between processors.

A key challenge in quantum computing has been to communicate quantum information between distant parts of a processor.

In a paper published in the journal Nature, the MIT researchers constructed “giant artificial atoms” from superconducting quantum bits, or qubits, connected in a tunable configuration to a microwave transmission line, or waveguide.

“Coupling a qubit to a waveguide is usually quite bad for qubit operations, since doing so can significantly reduce the lifetime of the qubit,” says Bharath Kannan, MIT graduate fellow and first author of the paper. “However, the waveguide is necessary in order to release and route quantum information throughout the processor. Here, we’ve shown that it’s possible to preserve the coherence of the qubit even though it’s strongly coupled to a waveguide. We then have the ability to determine when we want to release the information stored in the qubit. We have shown how giant atoms can be used to turn the interaction with the waveguide on and off.”

DISH picks VMware for 5G cloud-native O-RAN

DISH selected VMware's Telco Cloud solution for its 5G, cloud-native Open Radio Access Network (O-RAN).

VMware said its Telco Cloud will enable DISH to utilize software from leading vendors to optimize and accelerate its 5G network deployment. Additionally, it will provide DISH with enhanced automation, resiliency, security and flexibility. The VMware Telco Cloud provides an abstraction layer across multiple network domains and enables DISH to leverage hyper-scale public cloud capacity where needed, while maintaining core control points. The software-defined nature of the VMware Telco Cloud is part of the platform to support the DISH ecosystem of partners to accelerate 5G leadership in the U.S.

“VMware software will serve as a powerful foundation for our cloud-native, software-defined 5G network,” said Marc Rouanne, executive vice president and chief network officer, DISH. “By bringing together innovations such as the distributed cloud, edge computing and network slicing, this software will help us provide our customers with customizable, secure solutions that will be more cost-effective than legacy, vertically-integrated, hardware-reliant alternatives.”

“We’re excited to work with DISH to architect and build a state-of-the-art, nationwide cloud-first 5G mobile network platform,” said Shekar Ayyar, executive vice president and general manager, Telco and Edge Cloud Business Unit, VMware. “This software-led approach will enable DISH to innovate and deliver new services to all types of customers – enterprise, small business, and consumer – across the U.S.”

VMware certifies Network Functions Orchestration and Automation

VMware is expanding its Telco Cloud certification program to enable telco network functions partners to test the interoperability and readiness of their Virtual Network Functions (VNF) and Cloud-Native Network Functions (CNF) with the VMware Telco Cloud platform.

To date, more than 35 partners have received more than 170 certifications. The expanded program will offer two new certifications:

  • VMware Ready for Telco Cloud certifies network functions for deployment and lifecycle operations through VMware Telco Cloud Automation, a multi-cloud orchestration and automation platform. As part of this certification program, VMware collaborates with partners to create an ETSI-Compliant descriptor, as well as workflow, resource, and artifacts for a validated and tested Cloud Service Archive (CSAR). This level requires the partner to complete the VMware Ready for Telco Cloud Infrastructure certification as a pre-requisite.
  • VMware Ready for Telco Cloud Infrastructure, formerly known as VMware Ready for NFV, identifies telco network functions that interoperate with the core infrastructure layers of the VMware Telco Cloud, as referenced by the VMware ETSI-compliant vCloud NFV Reference Architecture. The focus of this certification level is on the virtualized infrastructure manager (VIM) based on VMware Cloud Director and VMware Integrated OpenStack and, shortly, CaaS (Container as a Service): VMware Tanzu Kubernetes Grid compatibility, as well as the compatibility with the platform’s core components: VMware vSphere for virtualized compute, VMware NSX for virtualized networking and VMware vSAN for virtualized storage. The program is available at no cost to VMware partners. Testing can be completed either in the VMware on-premise certification lab or in the cloud as a self-service model.
VMware said its expanded program enables partners to accelerate the onboarding and deployment of their 5G-ready services on the VMware Telco Cloud platform, thereby reducing communications service providers (CSPs) time to revenue. CSPs benefit from having access to advanced network functions and services, such as 5G Core components, that are ready to be deployed on the VMware Telco Cloud platform.

DISH takes over Boost Mobile and its 9.3 million subscribers

T-Mobile US completed its previously announced divestiture of Sprint’s prepaid wireless business to DISH Network Corporation, fulfilling a commitment that T-Mobile and Sprint made to the Department of Justice and to the Federal Communications Commission as part of their merger process.'

DISH paid $1.4 billion for the acquisition of Boost Mobile and its 9.3 million customers.

DISH said it will continue to invest in the Boost Mobile brand. John Swieringa, who serves as group president, retail wireless and COO, DISH, will lead Boost Mobile.

Additionally, the divested prepaid customers and new DISH wireless customers will have full access to the new T-Mobile network in a phased approach through a mobile virtual network operator (MVNO) arrangement, as well as through an infrastructure mobile network operator (MNO) arrangement enabling roaming in certain areas until DISH’s 5G network is built out. In connection with the closing of the DISH transaction, T-Mobile, Sprint and DISH entered into certain other ancillary agreements, including a spectrum purchase agreement.

Nokia now has 83 5G deals and a 27% RAN marketshare

Citing the effects of COVID-19 as well as a sharp decline in China, Nokia reported Q2 net sales of EUR 5.092 billion, down 11% from the EUR 5.694 billion a year earlier. However, Nokia reduced the volume of low margin services business, resulting in better-than-expected profitability and significant improvement in cash generation. There was a net profit of EUR 85 million, compoared with a loss of EUR 191 million a year ago.

  • Nokia's Optical business experienced COVID-19 supply constraints in Q2 but these are expected to ease in Q3
  • Nokia currently has 83 5G commercial deals and 32 live 5G networks
  • Nokia estimates its  4G+5G mobile radio market share at 27% excluding China
  • Nokia Enterprise confirmed 180 private 4G and 5G deals to date, an 18% yearly growth

Rajeev Suri, Nokia's outgoing CEO, states:


"At the start of the year, we said we would have a sharp focus on our Mobile Access business and improving cash generation. In both areas we continue to make good progress. Free cash flow in the quarter was positive €265 million, versus negative €1.0 billion one year ago, and Nokia ended Q2 with €1.6 billion of net cash, and €7.5 billion in total cash. Given our strong first-half improvement, we now expect free cash flow for full-year 2020 to be “clearly positive” compared to our earlier guidance of “positive”.

"In Mobile Access, we saw healthy improvements in our radio portfolio, where roadmaps are strengthening, costs are coming down, and product performance is rising. We have a particularly powerful portfolio in mid-band mobile radio, with proven products deployed with 55 customers, and the first live C-Band network demonstrated in the U.S. during the quarter. Pleasingly, our “5G Powered by ReefShark” shipments continue to increase and we believe we remain on track to reach 35% or better by year end. And, we now have 83 5G deals."

"Our continued momentum was demonstrated by the progress we announced after the quarter ended. These included the availability of a software upgrade that allows millions of Nokia 4G/LTE radios deployed to more than 350 customers to be migrated seamlessly to 5G; and plans to accelerate leadership in Open RAN. Nokia is the only global supplier fully committed to O-RAN with commercial 5G Cloud-RAN networks. We also announced an expansion of our IP routing business into the data center market and highlighted that Apple was deploying our technology at its data centers."

"This is my last quarterly announcement as CEO of Nokia and I want to close with a note of thanks: thanks to our shareholders, thanks to our customers, thanks to our many other stakeholders, and a particular thanks to the great employees of Nokia. You have constantly made me proud and I expect that you will continue to do so in the many years to come. Thank you all. It has been a pleasure and an honor."

Dell'Oro: Broadband access equipment spending to drop 7% in 2020

Global spending on broadband access equipment and CPE is expected to drop 7% in 2020, dipping to $11.4 B, before increasing 5% in 2021, according to a newly updated forecast from Dell'Oro Group. In January 2020 Dell'Oro forecasted a 5% decline in total revenue in 2020.

Some highlights:

  • Dell'Oro increased its five-year CAGR (2019-2024) from -2% from our January forecast to -0.9%. In response to the worldwide COVID-19 pandemic, new initiatives to improve broadband access are either underway or will be shortly. 
  • The five-year CAGR for PON equipment has been increased from 0% to just under 1%. China, which has historically accounted for anywhere from 65-80% of total PON spending, has peaked in terms of total ONT units consumed on an annual basis. The Chinese FTTH market has matured, with broadband penetration in the country reportedly nearing 80%. Though subscriber growth is slowing, there is still a tremendous installed base of subscribers that will continue to require new ONTs. This is especially the case beginning this year, when all three major operators begin purchasing 10 G units, based on either 10G EPON or the asymmetric XG-PON technologies. The 10 G upgrade cycle in China for ONTs will be extended over a longer period of time than the initial 1G EPON and 2.5 G GPON rollouts, as individual systems announce gigabit city initiatives.
  • The glut of DOCSIS channel capacity that helped push down cable equipment revenue in 2019 has actually been beneficial to operators this year as they have been able to address significant increases in both upstream and downstream traffic during the pandemic with minimal increases in spending.
