Why is Ericsson a good place to work?

Ericsson enables communications service providers to capture the full value of connectivity. The company's portfolio spans Networks, Digital Services, Managed Services, and Emerging Business and is designed to help our customers go digital, increase efficiency, find new revenue streams, and create new user experiences. Ericsson's investments in innovation have delivered the benefits of telephony and mobile broadband to billions of people around the world ensuring our solutions - and our customers - are at the forefront of innovation. We support networks that connect more than 2.5 billion subscribers. With over 100,000 employees and customers in 180 countries, we combine global scale with technology and service leadership. 40 percent of the world's mobile traffic is carried over an Ericsson network. And, our Technology for Good and Connect to Learn programs include creating technology that makes it easier to save lives, feed societies, bring technology to emerging markets and connectivity to remote areas, and grow businesses and prosperity.

At Ericsson, we give our employees the freedom to think big and navigate their career, on a global scale. We create technology that helps others, from helping people enjoy their favourite content to helping people recover from natural disasters by enabling better communications between rescue workers. Your ideas and innovations can turn into achievements that impact society and change the world, creating new connections, new possibilities, and new capabilities. We find that Ericsson is at its best when we bring together the diverse skills of our people. Working across business areas, across cultures, across geographical borders, across technical disciplines. More often than not, across ground-breaking solutions. Next generation technology can be staggeringly complex. But the simpler it is to use; the more people benefit from it. Join us and help build technology that makes it simple to connect with information, business, societies, and each other.

Our Exciting Opportunity

In cloud native environments, it is common to decompose applications into smaller, more manageable modules. These applications can sometimes consist of hundreds or even thousands of components with various levels of interaction. To be able to detect, predict, and handle issues and problems in an application, the ability to monitor these components is important. The goal is to have a richer, deeper, and more useful knowledge and context for understanding what is happening within a system.

The extended Berkeley Packet Filter (eBPF) feature in Linux offers the possibility to run small static programs attached to the kernel. These eBPF programs can be used to dynamically add capabilities to the operating system at runtime, and this is enables monitoring the components of an application and their interactions.

This project will investigate how to use eBPF to implement observability for cloud applications, collecting only the data relevant for a particular task.

You will

  • Deploy a microservice in a cloud environment.
  • Define the data to be collected.
  • Implement an eBPF-based program to collect the data.
  • Design and implement the algorithm for dynamically adjusting the subset of data which is relevant for each task.

The work will be supervised by researchers at Ericsson Research in Lund, Sweden, and the thesis will be concluded with an Ericsson internal presentation of the results.

To be successful in the role you must have

  • One semeter left of master level studies within electrical engineering, computer science, computer engineering or similar.
  • Experience with programming in the Linux environment.
  • Familiarity with virtualization and containers is recommended.

We wish to see a project with two students working together, with the goal of reaching as performant a solution as possible.
