DTN Network Management
Discussion between DTN and SM&C
2
DTN DTN provides applications with end-to-end communications even where (contemporaneous) end-to-end connectivity is not available (so long as there is eventual piecewise connectivity). It does this via hop-by-hop, store-and-forward message passing Application Application BP BP BP BP LTP LTP UDP UDP TCP TCP Encap Encap IP IP IP IP

DTNMP Operations I, the DTNMP manager, wish to define a new ‘type’ (or ‘page’) of telemetry: Combination of raw and computed values I, the DNTMP manager, want the following data: Report this value, once Report these raw values at this frequency for so long Report these computed values at that frequency for another so long If this predicate is true, report these values (page) I, the DTNMP manager, wish to invoke this command: Single command Group of low-layer commands If this predicate is true, do this command set

DTNMP as a An SM&C Service
SIS needs to Write the Yellow stuff: Combination of DTNM service and MAL-to-BP Binding defines interoperability? DTNMP as a An SM&C Service ‘DTNMP PDUs’ defined as a result of: The DTNM Service definition MO M&C Svcs MAL ‘base’ data types MAL-to-BP binding ?????????????????????????????

Whether defined independently or as a M&C Service, can still draw essentially the following boundaries around the service (which includes PDUs and interoperability).
