I see several references to ECN and CE marks yet no normative referecne to RFC3168 that defines these terms, nor any reference to RFC8257 which modifies the symatics of ECN signalling defined in RFC3168.  Could you add clarifying language please?

> Abstract:
>    A good congestion control for data centers (DC) should provide low
>    latency, fast convergence and high link utilization.  Since multiple
>    applications with different requirements may run on the DC network it
>    is important to provide fairness between different applications that
>    may use different congestion algorithms.  An important issue from the
>    user perspective is to achieve short Flow Completion Time (FCT).
>    This document proposes data center congestion control direction
>    aiming to achieve high performance while proving fairness.
