Many of the most common uses of the Internet today weren’t envisioned when it was created. In many ways, the success of the Internet and the TCP/IP protocol once envisioned by DARPA is pushing it to the limits. As a result, ensuring high-performance for end-users is complicated. Join Cloudflare experts for a talk that will describe the depth of these problems -- ranging from how routing breaks, to how shortage of IP space (under IPv4) hurts performance, to route leaks -- and how these issues lead to congestion and poor performance. They'll also discuss an approach to solving these challenges given the constraints.
