Hi Linda,

I don’t think there is any great reason why we didn’t continue to refresh this draft and take it to RFC. At the time of the last update there was a lot of churn in the flowspec area with respect to work on the bis draft, flowpsec-v2 and the best way to specify interaction between multiple actions. So I guess you could say that we wanted the dust to settle a bit.

This draft can and should be revived. It would be good to understand from my co-authors the current status of implementations. I can say that Nokia has implemented this draft for both IPv4 and IPv6, but only the redirect functionality, not the copy functionality.

-Adam

Subject: [ALU] will draft-ietf-idr-flowspec-redirect-ip-02 be revived?
Jim, Jeff, et al,

Our https://datatracker.ietf.org/doc/draft-mcd-rtgwg-extension-tn-aware-mobility/ needs to use Flowspec to influence the node (either on 5G UPF or directly connected to the 5GUPF) to steer a flow from 5G’s UPF to a specific underlay path based on the  5G services characteristics.

The approach described in  draft-ietf-idr-flowspec-redirect-ip-02 are useful for our purpose.   But the draft has been expired.

Just curious if the  draft-ietf-idr-flowspec-redirect-ip-02 be revived? Were there any reasons the draft didn’t move forward?

Thank you very much
Linda Dunbar
