Edge Computing Empowered: Optimizing Video Streaming Experience
Tech Team
Video streaming accounts for over 80% of global internet traffic. For streaming platforms, buffering ratio and start-up time are critical metrics directly impacting user retention.
Advantages of Unified Large File Slicing
Traditional caching strategies often treat the entire video file as a single object. CDN Engine utilizes a unified large file slicing technology, dividing all large files into standardized chunks for caching, regardless of the specific video format (without transcoding). This generic slicing mechanism offers two huge advantages:
- **Instant Seek**: When users drag the progress bar, the player only requests slices for that precise location, without downloading invalid previous data.
- **Parallel Fetch**: On cache miss, edge nodes can concurrently request multiple slices from the origin, vastly improving download speeds.
Intelligent P2P Coordination Between Nodes
For cold resources or traffic bursts, relying solely on origin fetching can cause massive bandwidth pressure. Our solution implements P2P intelligent coordination between CDN nodes. When a local node experiences a cache miss, the system automatically detects nearby nodes holding the resource and initiates high-speed transmission. This inter-node data transfer happens entirely server-side (without client involvement), reducing load on the origin server and ensuring high distribution efficiency.
