Hi Qin, > If my understanding is correct, Frank’s intention is not proposed to fall back to single datastore, split tree. His concern is how Does the non-NMDA client talk with NMDA compliant devices, suppose large amount of devices support NMDA. Using the original non-NMDA protocols, assuming the servers support both NMDA and non-NMDA. > Does the device need to support both NMDA model and non-NMDA model? Yes, assuming a heterogeneous mix of NMDA and non-NMDA servers. > Is this common case or corner case in real deployment senario. While the industry is transitioning to NMDA, it is an expected case. At some point, the IETF will obsolete non-NMDA support. > suggestions or guidelines defined in NMDA architecture and NMDA guideline(/rfc8407#section-4.23.3) seem to only assume NMDA client only talks with NMDA server, non-NMDA client only talks with non-NMDA server. True, but there’s no statement that a client or server cannot be both. Note also that the NC/RC-NMDA RFCs explain how clients can discover if a server supports NMDA. The intention is that the client would first try to use NMDA and, if not supported, fallback to non-NMDA. Kent // contributor
