Live Streaming

LiveStreaming: everybody in the swarm is viewing the same content at the same time. Comparable to television channels or a webcam feed.

planning before end of 2008

• Operational Give-To-Get: core P2P video engine
• BarterCast: link with sharing ratio enforcement
• SelectiveSeeding: seeding policy
• visualize your current score
  • Status and howto improve it
  • Allies + ratio and history
  • Recent helped peers
  • Pretty view of swarm, give-to-get connections

Give-To-Get

• assume some peers are malicious, but the majority follows protocol
• unchoke best neighbours
• based on recent behaviour (forwarded bytes in last 10 seconds)
• optimistic unchoke (every 20 seconds):
  • kick worst 4th unchoked neighbour (whom is not locked for ratio repay)
  • fill neighbourhood with:
    • 33% best supertrust peer (has best sharing ratio)
    • 33% if any: with you have debt (worst ratio to you)
    • 33% random

Some outdated information on previous live streaming trials is still online.
