Abstract
Origin offload is a key performance indicator of a content delivery network (CDN). This patent document presents unique methods and systems for measuring origin offload and applying those measurements to improve the offload. The techniques presented herein enable resource-efficient measurement of origin offload by individual servers and aggregation and analysis of such measurements to produce significant insights. The teachings hereof can be used to better identify root causes of suboptimal offload performance, to tune CDN settings and configurations, and to modify network operations, deployment and/or capacity planning. In addition, discussed herein are improved metrics showing offload in relation to the maximum achievable offload for the particular traffic being served.
