A significant fraction of the Internet traffic today is delivered via content delivery networks (CDNs). Typically, the CDN hauls data from content providers to its back-end servers, moves this data (via an overlay) to its front-end servers, and serves the data from there to the end users. This server-to-server (i.e., back-end to front-end) landscape provides a few unique perspectives as well as opportunities for solving some long-standing networking problems. In this talk, I will briefly discuss these perspectives and opportunities, and present one key measurement effort that leverages this landscape—quantifying the effect of path choices in the Internet’s core on end-user’s experiences.
