Performance Considerations

  • Latency targets (sub-150 ms) require tight retransmit windows and low-buffer playback; FEC overhead must be tuned per scenario.
  • Bandwidth savings scale with audience locality and relay density; sparse audiences see diminishing returns.
  • CPU/energy impact on relaying endpoints must be balanced against bandwidth savings, especially on mobile devices.

Challenges and Trade-offs

  • Complexity: Orchestration, multipath logic, and relay trust require sophisticated control systems.
  • Peer Trust & Privacy: Relay behavior must be attested; organizations may restrict which endpoints can relay.
  • NAT/Firewall Traversal: Reliance on STUN/TURN and possible operator cooperation for optimal paths.
  • Device Heterogeneity: Supporting a broad device set requires codec and compute fallbacks.
  • Inter-provider Coordination: Network-assisted features depend on ISP cooperation or SDN-enabled paths, which are not universally available.
