Dear WG,
We have just posted a new version of draft-liu-rtgwg-srv6-cc. In this version 01, the congestion notification message has been redesigned. We removed the "SRv6 Source Address", "Segment Routing Header (SRH)", and the complex "Behavior TLV". Instead, the format now directly includes essential fields: Priority, Argument, Target Bandwidth, and Slice ID, to make the solution more lightweight and practical for implementation. We39ve refined the description of the congestion control process, clarifying how notifications are propagated upstream and how nodes determine whether to handle congestion locally or forward the notification further. We would greatly appreciate your review and any feedback or suggestions you may have.
