There are several principles for reference:
1. Exercise quality: Exercises must cover core concepts, have a reasonable difficulty level, and preferably come with answers or explanations.
2. Practice orientation: Deepen theoretical understanding and cultivate application capabilities by solving problems.
3. Classics and reputation: Give priority to books that have been recognized by the academic community or learners for a long time.
1. Hybrid architecture (CDN+P2P):
- Use CDN to process backbone traffic, and edge nodes distribute through P2P to reduce the pressure on the central server (such as LivePeer trying to combine blockchain and P2P).
- Platforms such as Youku have experimented with such solutions, but they need to weigh the cost and effect.
2. Protocol optimization:
- Sliced transmission: Divide the streaming media into small pieces and improve efficiency through multi-path transmission.
- Dynamic priority: Dynamically adjust the data allocation strategy according to node bandwidth and latency.
- Buffering and preloading: Allow users to tolerate higher latency in exchange for more stable transmission (such as HLS/DASH protocol ideas).
3. Decentralized network exploration:
- Projects such as IPFS and BitTorrent Live have tried real-time streaming, but are limited by technical maturity and ecological support.
- Web3 projects (such as Theta Network) combine token incentives to encourage nodes to contribute bandwidth, which may promote development.
