Re: [re-ECN] FW: New Version Notification for draft-moncaster-congestion-exposure-problem-02

[Michael Menth <[e-mail]>]

Hi Toby,

I did a review of Sections 1-4. You find my comments in the attached 
doc. I also formulated a use case on meaninful policing, differentiating 
in per-flow and per-customer congestion policing and showing that the 
latter sets incentives for congestion-minimizing transport protocols and 
allows fairer tariffs (rewording required).

Kind regards,

    Michael
