Transport-Independent Path Layer State Management

ETH Zurich
This document describes a simple state machine for stateful network devices on a path between two endpoints to associate state with traffic traversing them on a per-flow basis, as well as abstract signaling mechanisms for driving the state machine. This state machine is intended to replace the de-facto use of the TCP state machine or incomplete forms thereof by stateful network devices in a transport-independent way, while still allowing for fast state timeout of non-established or undesirable flows.
