Hello,

We have proposed an updated version of the document on using in-band telemetry for high precision congestion control. 
The new version offers a discussion covering many comments and feedback from the group. Specifically, 
    1. The new version elaborates the privacy and security considerations for delivering this idea for Internet at large. 
    2. Also, it highlights the key insights and feasibility of our proposal with other switch-assisted congestion control approaches with  like XCP and RCP. 
    3. The document proposes several recommendations for adopting the HPCC++ algorithm with different transport protocols and QoS schemes.
If you have any comments, please let us know!

Best regards,
Rui - on behalf of the co-authors

Abstract:
   Congestion control (CC) is the key to achieving ultra-low latency,
   high bandwidth and network stability in high-speed networks.
   However, the existing high-speed CC schemes have inherent limitations
   for reaching these goals.

   In this document, we describe HPCC++ (High Precision Congestion
   Control), a new high-speed CC mechanism which achieves the three
   goals simultaneously.  HPCC++ leverages inband telemetry to obtain
   precise link load information and controls traffic precisely.  By
   addressing challenges such as delayed signaling during congestion and
   overreaction to the congestion signaling using inband and granular
   telemetry, HPCC++ can quickly converge to utilize all the available
   bandwidth while avoiding congestion, and can maintain near-zero in-
   network queues for ultra-low latency.  HPCC++ is also fair and easy
   to deploy in hardware, implementable with commodity NICs and
   switches.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
