DESCRIPTION:Live video stresses every layer of a CDN: traffic spikes hit te
 rabit scale in seconds\, latency budgets shrink to single-digit seconds\, 
 and a single congested peering link can stall millions of viewers. This ta
 lk 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\, pe
 er-aware user steering that exploits BGP and ECMP\, and the trade-offs bet
 ween channel affinity\, cache size\, and uplink utilization. We'll also to
 uch on observability with Prometheus and client-app telemetry enriched by 
 CMCD.
