Master Thesis - Global peering and anycast

Background

Netnod is a small high-tech firm based in Sweden which provides services at the core of the Internet, such as Internet-exchange services, transmission, DNS-services, and time and frequency services. Netnod is at the forefront of secure and robust services.

Thesis description

At Netnod we mainly design security through diversity, that is by composing systems through many different nodes in many different levels so that there is no single point of failure. In terms of security our systems focus on providing availability and integrity, even in extreme scenarios.

Several of our services are dependent on anycast routing and peering on nodes across the globe for availability. Announcing and de-announcing nodes is part of our toolkit for management traffic and global availability.

What should be the best-practices for ensuring availability of any global service; given events such as DDoS, faulty routing, anycast and peering?

This thesis concerns digging into this issue, and if possible, suggest solutions. This thesis concerns both implementation and evaluation of implementations.

Qualifications

This thesis project is aimed at students in computer science and engineering with an interest in networks, routing and peering.

Extent

Preferably two students, 30hp each

Practicalities

The students are expected to be partly present at the Netnod main office in Solna, Stockholm. The planned semester is spring of 2026.

Netnod will provide an on-site supervisor with relevant academic merits.

Netnod provides necessary equipment, reimbursement for travels, and a one time compensation upon completion of the thesis project.
