Edge Caching

Edge caching stores content closer to users to reduce latency.

What is Edge Caching?

Edge caching is a content delivery technique where video data is stored on servers located closer to viewers, rather than being fetched from a central origin server. By serving content from nearby locations, edge caching reduces delivery time and improves playback performance.

Why edge caching matters in OTT platforms

OTT platforms serve audiences across regions and network conditions, often at massive scale. Edge caching helps reduce latency, minimize buffering, and handle traffic spikes during live events or popular content releases while lowering load on core infrastructure.

How edge caching works in practice

When a viewer requests a video, the CDN checks if the required video segments are already cached at the nearest edge server. If available, the content is delivered immediately; otherwise, it is fetched from the origin, delivered to the viewer, and cached for future requests.

Where edge caching is used in streaming workflows

Edge caching is used across live streaming, video-on-demand, and FAST channels. It plays a critical role in improving startup time, reducing rebuffering, and maintaining consistent video quality across mobile apps, web players, and Smart TVs.
