M. Kuehlewind: AUTHOR [+2]
Congestion Exposure (ConEx) is a mechanism by which senders inform the network about expected congestion based on congestion feedback from previous packets in the same flow. ConEx concepts and use cases are further explained in [RFC6789]. The abstract ConEx mechanism is explained in [RFC7713]. This document describes the necessary modifications to use ConEx with the Transmission Control Protocol (TCP).
