Overview
What this challenge is about.
Compare HTTP/2 vs HTTP/3 video delivery over cellular networks in a controlled A/B experiment and earn your verifiable certificate.
The scenario
Streamwell competes in a saturated European streaming market where mobile viewing dominates and viewers abandon a stream after only a few seconds of buffering. Transport-protocol choices that were invisible on fixed broadband become decisive on congested and lossy cellular links.
The Brief
What you'll do, and what you'll demonstrate.
Quantify how much HTTP/3-over-QUIC improves over HTTP/2-over-TCP for over-the-internet video delivery across realistic cellular conditions, and recommend a transport direction for the 2026 content-delivery-network contract.
Earning criteria — what you'll demonstrate
- Design a controlled A/B experiment with well-defined cells and statistically justified sample sizes
- Operate a synthetic-client harness to produce reproducible network measurements under emulated cellular conditions
- Separate a treatment effect (transport protocol) from confounders such as TLS handshake and congestion control
- Compute and correctly interpret means, 95th-percentile values, and confidence intervals for skewed performance data
- Translate a technical measurement result into a defensible procurement recommendation

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Site Reliability Engineer
Reliability engineers constantly decide between infrastructure options under uncertainty. This challenge builds the muscle of running controlled network measurements, separating real effects from confounders, and shipping a reproducible result others can trust.
