Sifangds 2 Mp4 Exclusive

  • Transport: runs over UDP with optional QUIC fallback — rationale: lower header overhead, retransmission control.
  • Reliability: selective retransmit using sequence numbers; FEC optional for lossy links.
  • MP4 Packaging:
  • Security: DTLS/QUIC for confidentiality and integrity; token-based edge auth.
  • Workflow:

    • This paper proposes SifangDS 2 MP4 Exclusive, a lightweight protocol and system architecture for reliable, low-latency delivery of MP4 video segments in edge-assisted networks. We present the protocol design, caching strategies, segment packaging, adaptation logic, and an experimental evaluation comparing throughput, startup delay, and stalling against DASH over HTTP/2. Results show SifangDS 2 reduces startup delay by ~25% and rebuffering by ~30% under constrained bandwidth scenarios.

  • Baselines: DASH over HTTP/2 with same ABR logic; DASH+QUIC variant.
  • Metrics: startup delay, average bitrate, rebuffering ratio (rebuffer time / playback time), QoE score (weighted).
