In July of 2005, the IESG allowed the then-existing session mobility (Seamoby) working group's Candidate Access Router Discovery (CARD; RFC 4066) and Context Router Protocol (CXTP; RFC 4067) to be published as experimental RFCs with an associated warning, RFC 4065, informing everyone that both protocols were experimental only and therefore may never see widespread deployment. The purpose of this email is to query whether or not these Seamoby protocols have been deployed within production environments? If they have, I would like to learn how widespread their deployment has been and whether the infrastructures that have deployed them believe that this approach remains promising or not? If not, then what were the problems that were encountered? If so, then do they expect the use of this protocol to grow in popularity over time or not? Thank you for your attention to this query. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
