What Is a Content Delivery Network
Content delivery networks use multiple servers in many geographic locations that improve deliveries of static and streaming content. Global content requests automatically get routed to the closest servers, speeding up page loads, maximizing bandwidth and providing identical content regardless of Internet- or site-traffic spikes. Depending on traffic and number of nodes, the network’s algorithms select the best routing options to deliver optimum performance and avoid bottlenecks.
Users with high-speed connections often experience choppiness, loading lags and poor quality, especially when viewing live events or if they are located far from the hosting servers. CDNs minimize latency issues that cause image jitters, optimize delivery speeds and maximize available bandwidth for each viewer.
