This fundamental paper defined Application-Layer Framing (ALF) and Integrated Layer Processing.
This document is interesting historically. It is a light read, and it shows that the authors got quite a lot wrong! This study emphasized OSI, which they then believed to be inevitable; they did not realize that the IAB would accidentally kill OSI by embracing it in 1993.
A fundamental discussion of naming and addressing.
Abstract: This document describes the current state of the Internet from the architectural viewpoint, concentrating on issues of end-to-end connectivity and transparency. It concludes with a summary of some major architectural alternatives facing the Internet network layer.From Introduction: ... For the purposes of this document, "transparency" refers to the original Internet concept of a single universal logical addressing scheme, and the mechanisms by which packets may flow from source to destination essentially unaltered.
Fling is an application-layer security overlay whose focus is entirely on anonymity:"Fling is a new suite of internet protocols that perform the function of DNS, TCP, and UDP in a manner that's both untraceable and untappable. Fling protects clients from servers, servers from clients, and both from an eavesdropper in-between. The result is that anyone can serve or retrieve any data, without fear of censure."
...
"Fling works by preparing a "route ball" - onion skin layers of crypto, describing a route, in which each step only knows where the immediate preceding and following steps. This is used to route an encrypted message payload. Route balls are found by a distributed host name lookup mechanism that shares the search burden and leaves no central server that can be coerced to drop names. Instead, each subtree can allocate - and revoke - "dependent names", but anyone can start a new root subtree. Thus, subtrees can build a reputation for trust, and police it, while no-one can ultimately be censored completely."
