Abstract:

   Heterogeneous memory networks (CXL pools, HBM/DDR/SRAM hierarchies,
   processing-in-memory arrays) form a big memory system, which exposes
   fragmented addressing to ML inference runtimes.  This document
   describes Memory DNS (MemDNS), a semantic-addressing framework that
   applies DNS principles -- domain names, hierarchical delegation,
   caching, TTL, and authoritative records -- to tensor data placement
   in Big Memory Systems (BMS), deployed as limited domains (RFC 8799).
   The focus is "automated pivoting": the resolution and control
   machinery that automatically switches data access paths (replica
   selection), migrates data across media (placement pivoting), and
   recovers from faults (failover pivoting), driven by closed-form
   decision models (Appendix A; key logic pseudo-code in Appendix C)
   instead of ad-hoc thresholds.  The document specifies record
   semantics, resolution flow, cache/TTL behavior, delegation, pivot
   decision models, and protocol considerations, together with a
   reference implementation summary.
