ALC track advantages

• Completely separated functionality

  • No interdependencies between reliability protocol (FEC) and congestion control protocol (WEBRC)

• Massively scalable reliable content delivery

  • A single sender is adequate

    • No feedback from receivers to the sender
    • A single sender for millions of concurrent multicast receivers
    • Seamless support for both multicast and unicast
  • Minimizes delivery time for each receiver

    • Receivers can start asynchronously
    • Aggressively uses bandwidth between each receiver and sender
    • Minimal amount of data needs to arrive at each receiver to recover content
  • Friendly to competing flows
