Dear all,
We just submitted a new version (-03) of fantel problem statement draft to
incorporate the comments received both on the list and offline. Thanks again
for all the review, discussion and suggestions.
The major changes in this version include:
- A new coauthor joined: Reshad Rahman.
- In the introduction section, some descriptions about the hardware capability
in detecting network condition change at fine-grained time scales were added,
which shows the gaps in fast network notifications.
- The expected operating time range of fast network notifications was
clarified.
- The content in section 3 and section 4 was reorganized to improve readability
and avoid duplication.
- The descriptions about ECN mechanism were corrected.
- Figure 1 was updated to better reflect the problem space in section 4.1.
- Some explanation about the content of Table 2 was added.
- Some description about multiple recipients of the same notification was
added.
- The security considerations section was enhanced.
As always, further review and discussion are appreciated.
One thing for open discussion is, whether we should keep using the term
"FANTEL" which was introduced at the BoF, or change it to something like “FANN
(FAst Network Notification)" to better reflect the scope of this work? Any
feedback is welcome.
The authors believe this version is in a good shape for the RTGWG to consider
adoption or a consensus call. And we would like to see these problems being
worked on in the IETF. Guidance from the AD and the RTG chairs are much
appreciated.
Best regards,
Jie (on behalf of coauthors)

Abstract:
Modern networks require adaptive traffic manipulation including
Traffic Engineering (TE), load balancing, flow control, and
protection, to support high-throughput, low-latency, and lossless
applications such as Artificial Intelligence (AI) /Machine Learning
(ML) training and real-time services. A good and timely
understanding of network operational status, such as congestion and
failures, can help to improve network utilization, enable the
selection of paths with reduced latency, and enable faster response
to critical events. This document describes the existing problems
and why a new set of fast network notification solutions are needed.
