Hello ICCRG members,

Alibaba, Intel, and Mellanox have worked on an INT-based High Precision Congestion Control algorithm: HPCC++. We have posted an initial draft that can be found at
https://www.ietf.org/id/draft-pan-tsvwg-hpccplus-02.txt

The key design choice of HPCC++ is to use inband telemetry to provide fine-grained load information, such as queue size and accumulated tx traffic to compute precise flow rates. This has two major benefits:
1. HPCC++ can quickly converge to proper flow rates to highly utilize bandwidth while avoiding congestion;
2. HPCC++ can consistently maintain a close-to-zero queue for low latency.

We would love to hear your comments and feedback.

Best regards,

Rui Miao
