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!

Name: draft-miao-iccrg-hpccplus Revision: 00 Title: HPCC++: Enhanced High Precision Congestion Control Document date: 2021-04-22 Group: Individual Submission Pages: 16 URL: https://www.ietf.org/archive/id/draft-miao-iccrg-hpccplus-00.txt Status: https://datatracker.ietf.org/doc/draft-miao-iccrg-hpccplus/ Htmlized: https://datatracker.ietf.org/doc/html/draft-miao-iccrg-hpccplus Htmlized: https://tools.ietf.org/html/draft-miao-iccrg-hpccplus-00 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. The IETF Secretariat
