A Recursive Network Architecture

The Recursive Network Architecture (RNA) explores the relationship of layering to protocol and network architecture. RNA examines the implications of using a single, tunable protocol for different layers of the protocol stack, reusing basic protocol operations across different protocol layers to avoid reimplementation. Its primary goal is to encourage cleaner cross-layer interaction and to support dynamic service composition, and to gain an understanding of how layering affects architecture. This document provides a preliminary description of RNA, its rationale, and discusses its features and challenges.
