HTTP as the narrow waist of the future internet

Over the past decade a variety of network architectures have been proposed to address IP's limitations in terms of flexible forwarding, security, and data distribution. Meanwhile, fueled by the explosive growth of video traffic and HTTP infrastructure (e.g., CDNs, web caches), HTTP has became the de-facto protocol for deploying new services and applications. Given these developments, we argue that these architectures should be evaluated not only with respect to IP, but also with respect to HTTP, and that HTTP could be a fertile ground (more so than IP) for deploying the newly proposed functionalities. In this paper, we take a step in this direction, and find that HTTP already provides many of the desired properties for new Internet architectures. HTTP is a content centric protocol, provides middlebox support in the form of reverse and forward proxies, and leverages DNS to decouple names from addresses. We then investigate HTTP's limitations, and propose an extension, called ...
