The image is a technical illustration titled "Proactive CDN." It visually represents the workflow of content delivery in a network using a proactive Content Delivery Network (CDN) system. The illustration is divided into vertical sections labeled as "Application," "Edge," "Origin," "Webi," "Content priming," and "Store." These sections indicate different stages and components involved in the content delivery process.
Arrows are used to denote the flow of data and requests between these components. For example, a "Manifest request" is sent from the "Application" to the "Edge," which then requests a "Manifest file" from "Origin." The "Edge" retrieves a "Video segment" from "Origin" and sends it back to the "Application." Additionally, "Content priming" receives a "Priming hint" from "Webi" and sends a "GET (URL1)" request to "Store," which then returns a "Video segment."
The chart also includes a "Total time" indicator on the left, showing the overall duration of the process. The colors used are primarily blue and orange, which distinguish different stages and actions. The illustration serves as an informative guide on how a proactive CDN system operates, emphasizing efficiency in data retrieval and delivery.
