Description

In this session, we explore a paradox at the heart of network performance: despite decades of progress in infrastructure, the application layer fails to notice.

We’ll look at this problem from the application layer perspective, and trace how design embedded in TCP, congestion control, and buffering mechanisms ignore the benefits of modern networks. The result is a global pattern of “invisible inefficiency” where improved infra delivers only theoretical gains, not visible to the software sitting atop it.

Ultimately, we have to align application layer with the physical realities of the networks that carry it. Because until we do, our infra investments will remain invisible to those who seek new use-cases and better user-experience.
