A Framework for Signaling Flow Characteristics between Applications and the Network
Amine Choukir, Reinaldo Penno, Charles Eckel, Toerless Eckert · 2013
This document provides a framework for communicating information elements (a.k.a. metadata) in a consistent manner between applications and the network to provide better visibility of application flows, thereby enabling differentiated treatment of those flows. These information elements can be conveyed using various signaling protocols, including PCP, RSVP, and STUN.
