CTO's comments about the latest article

‘The rapid growth of video streaming services continues unabated, and a steadily increasing percentage of video consumption is now happening on mobile networks. The trouble is, network congestion during popular viewing times can easily lead to degradation in video streaming quality (stalling, pixelization and so on) that negatively impacts the users’ QoE. To meet user expectations and remain competitive now and in the future, it is crucial for both mobile network operators and media service providers to be able to accurately assess their users’ perception of video quality.

The latest Ericsson Technology Review article explores how the ITU-T’s new P.1203 standard can help to ensure the delivery of consistently high video QoE – particularly in wireless cases, with significant fluctuations in available bandwidth.

Note: As of July 1st, Ericsson will have a new CTO, and Ericsson Technology Review will have a new publisher. I want to take this opportunity to welcome Erik Ekudden and wish him the best of luck in his new roles. I also want to thank our readers for your interest and engagement over the years – it has been both a pleasure and an honor to serve as ETR publisher.

Video has become the dominant driver of internet traffic globally, taking up the majority of bandwidth on most networks around the world. Network congestion during popular viewing times frequently manifests itself as a degradation in video streaming quality (stalling, shifts in resolution, pixelization, changes in frame rate and so on) which frustrates and annoys viewers. To overcome this challenge, mobile network operators and media service providers urgently require solutions that can provide an accurate estimation of video QoE. Full implementation of the P.1203 standard would be a significant step in the right direction.

DevOps – an interactive approach to product management, development, deployment and operation – has an important role to play in helping equipment vendors and telecom operators meet 5G requirements. In light of this, Ericsson has worked closely with open source communities such as OPNFV and academic partners to define DevOps as it applies to next-generation telecom networks, identifying the specific steps of the DevOps cycle that are most relevant for 5G infrastructure. This work has resulted in the creation of a DevOps reference pipeline for a 5G business slice, as well as processes and advanced features supporting dynamically software-defined network functions and infrastructure.

IoT-based systems will require a high level of decision making automation both in terms of infrastructure management and within the logic of the IoT applications themselves. Decision support systems (DSSs) are an essential tool in this context on account of their ability to enhance human decision-making processes with machine intelligence. The cognitive automation framework that we have created at Ericsson speeds up the development and deployment of intelligent DSSs by reusing as much knowledge as possible, including domain models, behaviors and reasoning mechanisms. The framework substantially reduces operational costs for IoT-based system management by enabling DSSs to make decisions about how to adapt to changes in their context and environment with minimal or no human interaction.

CTO's editorial for latest magazine

The latest issue of Ericsson Technology Review presents a wide range of ideas and solutions that boost capacity, efficiency and security, as well as the latest technology to help you better understand the needs of your users. It also features an article by guest writer Stefan Larsson, associate professor in technology and social change at Lund University Internet Institute.

Dr. Larsson is an expert on digital socio-legal change, including issues of trust, consumption, traceability and privacy. He argues persuasively that the long-term success of the digital economy will be dependent on consistently high levels of both technological and sociological trust among users, and explains his view of what service providers must do to preserve them.

As always, I hope you find the contents of the magazine relevant and inspiring. All of the articles included in this issue are available individually on our website, through the Ericsson Technology Insights app and on SlideShare. Please feel free to share them via e-mail or social media.
