Episode: Edge-of-Your-Seat Streaming: inside waipu’s terrabit-scale live-video CDN (denog17)
Description: Live video stresses every layer of a CDN: traffic spikes hit terabit scale in seconds, latency budgets shrink to single-digit seconds, and a single congested peering link can stall millions of viewers. This talk walks through how we built a custom Golang edge stack that now serves 5.5 Tbps across five German PoPs. We’ll unpack the caching hierarchy, peer-aware user steering that exploits BGP and ECMP, and the trade-offs between channel affinity, cache size, and uplink utilization. We'll also touch on observability with Prometheus and client-app telemetry enriched by CMCD.
