Hi Carsten, Thanks for this pointer since the I-D frenzy indeed makes things easily 'disappear'. This is an interesting approach, effectively addressing at invocation level. What is striking is that you see this being done in a DNS-based resolution (requiring short TTLs, possibly VERY short, and no client caching). Do you see your approach being reconcilable with the dyncast architecture, as proposed in the draft? Best, Dirk -----Original Message----- From: Dyncast [mailto:dyncast-bounces@ietf.org] On Behalf Of Carsten Bormann Sent: 22 February 2021 23:28 To: dyncast@ietf.org Subject: [Dyncast] Instance Affinity (draft-bormann-dyncast-affinity-00.txt) You may not see this because of the I-D frenzy, but I thought I might alert you anyway. I have written a little draft that proposes a way to obtain service instance affinity without building network state that needs to scale with the number of clients/service invocations. Feedback would be welcome if you like exploring ideas like this.
