Technology

Layered redundancy, 2026-grade performance, end-to-end observability, and disruption-resistant design.

Layered architecture

  • • Geo-distributed main + backup ingest
  • • Active-active origin (packaging + ABR + recording)
  • • Multi-region PoP edge with automatic failover
  • • Security policies (token/geo/domain) and rate control

Observability (QoE)

  • • Stream health: bitrate, fps, dropped frames
  • • QoE: TTFF, buffering ratio, error rate
  • • Viewer analytics: concurrent users, geo, device
  • • Alerts: email/webhook + escalation

Typical 2026 server stack

Streaming-focused hardware tuned for throughput, latency, and reliability. Different profiles are used for PoPs and origin.

CPU & acceleration
AMD EPYC / Intel Xeon • AVX • optional GPU transcode
Storage & cache
NVMe caching • origin replication • library/recording tiering
Network
25/40/100G uplink • multi-carrier • redundant switching

Redundancy & failover

Ingest
Main + backup with automatic switching and health checks.
Origin
Active-active packaging/recording with data replication.
Edge
Automatic PoP fallback and congestion-aware routing.
