Introduction Motivation: Video over best-effort Internet
Broadband => more access bandwidth End-to-end (E2E) => constraints due to path
congestion Virtual extension of broadband access pipe E2E using
multi-paths
Path Diversity: dimensions Aggregate Capacity Delay diversity Loss diversity Correlations in path performance characteristics
Key: Match inherent content diversity to path diversity

Motivation: Internet Path Congestion limits E2E bandwidth
Internet
Server Access Link
Client Access Link

Access Link Speed
Performance Saturation (even w/ many flows/path)

Multi-paths?
Overlays or peers can provide path diversity even if multi-paths not available natively in the Internet.
Issue: diversity of performance (b/w, delay, loss), possible correlations…
