Abstract:

   [I-D.ietf-tiptop-usecase] and [I-D.ietf-tiptop-ip-architecture]
   describe key characteristics, use cases, requirements, and an IP
   architecture for deep-space (lunar, Mars, and beyond) surface and
   orbital-relay networking, characterized by long, variable,
   asymmetric propagation delay (single-digit to tens of minutes
   one-way), scheduled/intermittent connectivity windows, and severely
   constrained link capacity.  Section 8.2 of
   [I-D.ietf-tiptop-ip-architecture] addresses the configuration-
   management plane for this environment (NETCONF, RESTCONF, and SNMP
   transport selection and RTT-adjusted client timeouts), but neither
   document addresses the fault and performance dimensions of
   Operations, Administration, and Maintenance (OAM): fault detection,
   performance measurement, and reachability verification.

   This document identifies why conventional terrestrial OAM
   techniques (active round-trip probing such as ICMP Echo, BFD, or
   TWAMP; assumption of continuous connectivity) do not transfer
   directly to this environment, and proposes candidate adapted
   approaches -- passive, store-and-forward telemetry batched to
   contact windows; on-board local health self-diagnosis with delayed
   reporting; and confidence-interval-based reachability assessment in
   place of binary up/down status -- as a starting point for OAM
   discussion within the TIPTOP working group.  This document
   explicitly does not propose use of the Bundle Protocol or DTN
   architecture, both of which are out of scope for TIPTOP per its
   charter; where CCSDS space-data-system telemetry conventions are
   mentioned, it is as informative background only.
