Description: Link performance monitoring in the context of cloud CDNs (Content Delivery Networks) refers to the practice of tracking and analyzing metrics that determine the effectiveness and efficiency of network links connecting CDN servers to end users. This process involves collecting data on latency, bandwidth, packet loss, and other key indicators that affect user experience. Through monitoring tools, companies can identify bottlenecks, optimize content delivery, and ensure that users receive content quickly and reliably. The importance of this monitoring lies in its ability to improve service quality, reduce page load times, and ultimately increase customer satisfaction. Additionally, it allows organizations to anticipate issues before they impact users, facilitating a proactive response to any network inconveniences. In a world where speed and content availability are crucial, link performance monitoring becomes an essential tool for businesses that rely on online content delivery.
