Near Term Prototyping  MIB Development  Rapid development exposes data and metrics from reference DTN implementations  ION/DTN2/others  Based on Existing IP Network Management Protocols  SNMPv3, Netconf  Testing on IP-based networks with SNMP Gateways

Current Successes Performance data from DTN Implementations identified MIBs identified for DTN Initially extracted from DTN2 implementations, provided by BBN and maintained by GRC. Ohio University inspects ION shared memory to construct a MIB ION NM status queried via SNMP (via open standards visualizations such as openNMS) Modifying terrestrial implementations to work over high latency Netconf Work ongoing within MANET research group to modify netconf to support verify- commit commands to roll-back bad configuration changes to remote nodes. Proposed CNMP protocol for extending Netconf to support rudimentary sanity checks on configuration changes. SNMP gateways Provide visualization into status via report-to EIDs to an SNMP gateway.

Roadmap  Abstract SNMP Data Model  MIBs collectively implement a data store of local data collection  The SNMP agent is a local data manager for its data store  The SNMP agent is also a data aggregator to the network  Incremental Improvement of Existing Technology  Extend Netconf to work absent sessions  Provide subnet gateways for interfacing with SNMP systems  Introduce Data Aggregation  Collect high rate data locally, publish fused/trended/conditioned data remotely.  Requires some configuration at each node to define transformations  Eases bandwidth requirements on links  Different NM data over time, or in response to conditions  Report MIB : configurable aggregation of fused local data
