Hi WG,
fantel mainly focuses on addressing traffic engineering and congestion
control within DC. We propose a new draft to further explore fantel in
distributed RoCEv2 network.
Comments and discussions are welcome!
Thanks!

Title: Fast congestion notification for distributed RoCEv2 network based on
SRv6
Date: 2025-03-02
Group: Individual Submission

Abstract:
AI services (e.g. distributed model training, separated storage and
model training) drive the need to transmit RMDA packets through SRv6
tunnels in WAN. RoCEv2 is the most popular open standard for
achieving RDMA and network offloads over ethernet, with its
congestion control based on the combination of PFC and ECN. The
document defines the fast congestion notification for distributed
RoCEv2 network based on SRv6 tunnels, and further extends PFC and ECN
to achieve precise flow control and end-to-end congestion control.
