Automate performance-fault localization in cloud systems to minimize downtime

Netflix, Dropbox and Gmail are just a few of the popular web services that rely on virtualized cloud systems. According to Statista, the number of Netflix streaming subscribers worldwide is currently around 33 million, while Google’s e-mail service has an estimated 1 billion active users, and Dropbox has 500 million. With this many end users expecting high-quality of service, cloud service providers are under pressure to minimize service disruptions and downtime.

Flexible networking hot trend at SIGCOMM 2016

ACM SIGCOMM is the flagship annual conference in the field of computer and data communication networks. Ericsson was a gold sponsor of this year’s event, we were there to talk about research in SDN, NFV, 5G, network programmability and orchestration – and we spotted some interesting trends. In this post, we’ll share insights from SIGCOMM 2016 and link to some great reading material.

5G security is unlike anything you’ve seen before

We are going to have to think differently than during previous transitions if we are to successfully meet the network demands of a Networked Society. This is because 5G is different. 5G systems are the next step in the evolution of mobile communication and they will need to provide capabilities not only for voice and data communication as we know it today, but also for new use cases and new industries. The new wave of smart, connected devices and applications will bring with them as-yet-unknown security issues.

Research will play a crucial role in making 5G secure. As Professor of the Department of Electronics (within the School of Information and Communication Technology) at the Royal Institute of Technology (KTH) Stockholm, I have been collaborating with Ericsson on a project about 5G security.

LTE latency reductions: preparing for 5G

Since the dawn of LTE, the main focus for telecoms researchers has been to improve the peak rate, while response time, or latency, has only improved very little.

Now it’s time for a major leap in LTE latency reduction. Read on to learn about the new techniques that are the result of our leading research in this field.

D2D communication pushes the boundaries of future telecom systems

It’s no secret that today’s networks are carrying exponentially more traffic as demand from new devices and their applications increase. The rising traffic being generated by smart devices and mobile broadband services is on course to becoming too much for network resources such as spectrum to handle.

A new research initiative is underway to address this. The joint project sees Ericsson Research, Wireless@KTH and the Automatic Control Lab of the Royal Institute of Technology (KTH) in Stockholm collaborating not only to investigate how to better support D2D communication but also the opportunities it presents in 5G networks.
