Master Thesis: Externalize State between Processes

Technology, Data & Digital · Software & Web Development · Software Engineering · Embedded Systems

In short

This master's thesis project focuses on investigating and evaluating methods for externalizing state between separate processes in high-performance Radio Access Networks (RANs). The goal is to improve resilience and reduce service interruption by potentially using techniques like shared memory or the DPDK multi-process model.

Responsibilities

Investigate current research and engineering approaches for externalizing and sharing state between processes, with emphasis on high-performance packet-processing systems.
Select and compare suitable state-externalization methods.
Prototype at least one method with the DPDK multi-process model as a primary candidate.
Measure the impact on RAN function performance (e.g., traffic throughput, resource consumption, migration time).
Assess the expected resilience improvement compared with a design in which state is kept only within an individual process.
Conclude the thesis with a result presentation for the Ericsson team.

Requirements

Master´s students in electrical engineering, computer science, or similar.
Interest in high-performance packet processing, distributed systems, or resilient software.
Interest in process communication, state management, and performance evaluation.
Analytical approach with the ability to investigate, prototype, and evaluate solutions.
Clear technical communication skills, both written and verbal.

Benefits

Outstanding opportunity to use skills and imagination to push the boundaries of what's possible.
Build solutions never seen before to some of the world’s toughest problems.
Be challenged but not alone; join a team of diverse innovators.
Opportunity to go beyond the status quo to craft what comes next.
