Abstract:
Congestion Exposure (ConEx) is a mechanism by which senders inform
the network about the congestion encountered by previous packets on
the same flow. In order to make ConEx information useful, reliable
auditing is necessary to provide a strong incentive to declare ConEx
information honestly. However, there is always a delay between
congestion events and the respective ConEx signal at the audit. To
avoid state and complex Round-Trip Time estimations at the audit, in
[draft-ietf-conex-abstract-mech] it is proposed to use credit signals
sent in advance to cover potential congestion in the next feedback
delay duration. Unfortunately, introducing credit does not provide
incentives to honestly report congestion. This document lists
potential issues regarding the proposed crediting and discusses
potential solutions approaches to interpret and handle credits at the
audit.
