[conex] Fwd: New Version Notification for draft-wagner-conex-credit-00.txt

[David Wagner <[e-mail]>]

Hi all, 

we submitted a new draft describing potential definitions of credit and credit handling in the audit. 
This is meant as basis for discussion and we would appreciate feedback, hopefully leading to final definition of credit in the abstract-mech document soon.

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.
