Master Thesis: Performance and Scalability of MXL for Software-Based Live Media Production

Net Insight (Nasdaq Stockholm: NETI B) is a Swedish media technology company based in Solna, Stockholm. Its Nimbra products are

used by broadcasters, production companies and service providers around the world to transport live video for sports, news and

entertainment.

Nimbra Edge is Net Insight's cloud-native platform for live media transport. It runs in public, private and hybrid cloud

environments and controls both software and physical media-processing appliances. Live streams can be transported using

technologies such as RIST, SRT and Zixi, and processed, monitored or transcoded along the way.

The Nimbra Edge team works across this entire chain, from the control plane and user interface to low-latency video and audio

processing and transport. We are looking for master's thesis students interested in real-world problems in live media systems. The

topics below are intended as starting points, and the exact scope can be adapted together with the student and university.

Which system, workload and deployment factors have the greatest impact on the performance and scalability of MXL-based live media

pipelines?

MXL (Media eXchange Layer) is an open-source SDK for exchanging uncompressed video, audio and data between software media

functions. Investigate its performance in realistic live-production workloads and build a reproducible benchmark that can be used

to understand where its practical limits and bottlenecks are.

Useful measurements could include end-to-end and tail latency, jitter, CPU usage, memory bandwidth, memory footprint, missed

real-time deadlines, throughput and the maximum number of streams a system can sustain.

Where useful, MXL can also be compared with a simpler reference implementation, such as a minimal shared-memory producer–consumer

pipeline, to estimate the overhead introduced by the media exchange layer itself.

The exact experiments do not need to cover all of these areas. A thesis could instead select a small number of system variables

and investigate them in depth, with the benchmark and methodology forming an important part of the contribution.

Net Insight (Nasdaq: NETI B) provides the highest performing, most open video transport and media cloud technology for content

providers as the industry standard for flexibility and service across live contribution, distribution and remote production media

workflows.

For over 25 years, the world’s leading content owners, broadcasters, production companies, service providers and enterprises have

trusted Net Insight’s Emmy® Award winning Nimbra technology to guarantee media delivery. Today, Net Insight partners with hundreds

of customers in over 70 countries to ensure media flows across managed and unmanaged IP networks, and the cloud – from anywhere,
