Real user monitoring (RUM) global traffic management improves the availability, latency and throughput of websites, downloads, IP Videos and mobile apps using real-time data driven optimization of clouds, data centers and CDNs. Test objects are probed to collect actionable, comparative data about the providers and platforms measured. When someone visits a site, the browser instantiates the Radar client, which waits until two seconds after the browser’s onLoad event and then downloads instructions. Instructions specify which platform to measure next during the session, picked from among the community platforms and any private platforms specific to that community member. The client initiates up to three measurements for the platform it is instructed to measure. Test objects are deployed to every major CDN and cloud provider and any private platforms indicated.
