Abstract
When developing a new application layer protocol the question about its foundation arises. The decision will be impacted by various factors but the ability for the solution to be deployable in today's Internet will certainly play a big role since various intermediaries may lead to a brittle communication architecture. The waist of the hourglass has changed over time: new applications have to run on top of UDP or TCP. Protocol designs that use other transport protocols have turned out to be undeployable on the public Internet. Running protocols on bare IP is also doomed to fail. This change is not theoretic in nature but has real-world implications for protocol designers. There is also a trend to run applications on top of HTTP/HTTPS. The author seeks more input from the wider IETF community about the deployment situation of protocol filtering by intermediaries and on the impact for protocol designers.
