The provided code snippets and explanations detail the implementation of a hybrid download system that leverages both BitTorrent (P2P) and traditional HTTP for downloading assets. This approach aims to optimize download speeds by prioritizing P2P when available, while ensuring fallback to HTTP if P2P fails or is not an option.
Key Components
-
Metadata Consumer
- The
buildHybridMetadatafunction constructs the hybrid distribution metadata from asset objects inindex.json. - It ensures that web seeds include direct URLs for fallback purposes.
- Flags like
torrentFirst,eligible, and others control download strategies based on availability of torrent metadata.
- The
-
Hybrid Download Coordinator
- The coordinator executes actual download logic, prioritizing P2P downloads when possible.
- If a P2P download fails, it falls back to HTTP or web seeds for downloading the asset.
